How OmniSeal seals Work
OmniSeal jackets are precisionmachined from PTFE, filled PTFEcomposites and other highperformance polymers. OmniSealseals with PTFE jackets are serviceableat temperatures ranging fromcryogenic to + 300°C and are inertto virtually all chemicals exceptmolten alkali metals, fluorine gas athigh temperature and chlorinetrifluoride (CIF3).
OmniSeal seals are available with avariety of spring energisers, eachhaving characteristics to meetspecific requirements. Spring loadingcan be tailored to meet critical lowfriction requirements in dynamic applications, or extremely highloading often required for cryogenic
sealing. Springs are fabricated fromcorrosion-resistant metals such as300 Series and 17-7 PH stainlesssteels, Elgiloy®, Hastelloy®and Inconel.
OmniSeal seals with elastomer O-ringsused as energisers (nitrile, silicone,Fluoroelastomer, OmniFlexTM, etc.)are also available by contacting the factory.
The geometry of the OmniSealinstalled in the gland, providespositive resistance to torsional orspiral failures often found in O-rings.OmniSeal seals (with metal springs)have unlimited shelf life and are notsubject to age controls normallyimposed on elastomeric seals.
OmniSeal Components The OmniSeal is a spring actuated,pressure assisted sealing device con-sisting of a PTFE (or other polymer)jacket, partially encapsulating a corro-sion resistant metal spring energiser.
When the OmniSeal is seated inthe gland, the spring is undercompression, forcing the jacket lipsagainst the gland walls therebycreating a leak-tight seal.
The spring provides permanentresilience to the seal jacket andcompensates for material wear andhardware misalignment or eccentrici-ty. System pressure also assists inenergizing the seal jacket. Springloading, assisted by system pressureprovides effective sealing at both lowand high pressures.

Static Seals andDynamic Seals
The two basic types of sealingapplications are STATIC SEALS andDYNAMIC SEALS. In static sealingthere is essentially no relative motionbetween the seal and the hardwaremembers. An example would be aseal clamped between boltedflanges.
In dynamic sealing there is relativemotion between the two sealingsurfaces. A typical example wouldbe the rod and piston seals in ahydraulic cylinder.
There are two directions of motionin dynamic sealing, reciprocating orlinear motion, and rotary (includingoscillating) motion.
Occasionally there may be acombination of both static anddynamic applications. An additionalfactor to be considered is theorientation of the seal in thehardware. Seals that are compressedin a radial direction are called radialseals, again using rod and pistonseals as examples.
Seals that are compressed in adirection parallel to the axis arecalled Face Seals, the flange gasketbeing a typical example.
Typical installations are shown onPage 26.
Selecting anOmniSeal Design
Saint-Gobain Performance Plasticsmanufacturers and markets a varietyof basic styles of spring energisedPTFE Fluoroloy® seals. Several of thesedesigns can be used interchangeablyin the same gland.
The recommendations that followare intended as a general guide andshould be used together with thetables and dimensional charts thatappear on the following pages.Should you require additional assis-tance, please contact the factory. For complete contact informationsee the inside back cover.

Radial Sealsin Static ServiceWhile most of the OmniSeal designscan be used as static radial seals,the OmniSeal 103A, Page 16, isgenerally recommended for thisservice. Its moderate to high springload provides positive sealing undermost static sealing conditions.
Radial Sealsin Reciprocating MotionReciprocating radial seals are themost common OmniSeal applica-tions. For rod and piston sealing andsimilar applications, the OmniSeal400A, Page 18, is recommended forgeneral purpose sealing at low tomoderate pressures. This series has alow load, high deflection spring which provides low friction sealing, long wear life, and compensates forminor hardware eccentricity ormisalignment.
OmniSeal APS (Advanced PitchSpring), Page 20, uses a uniquedesign of a round wire springenergiser which has the advantageof producing an almost constantspring load over a wide deflectionrange. This type of seal accommo-dates variation in hardware dimen-sions (tolerances) and/or provideseffective sealing loads over a largeseal wear allowance. Also, it can bewound in very small coil diameters,which makes it particularly suitablefor miniature seals and sealsrequiring low friction values.
For better sealing at low speeds, the OmniSeal 103A, Page 16, isrecommended. The higher springload provides positive sealing withsome increase in seal friction.Particularly suitable for medium tohigh pressure service, the 103A isalso an excellent rod seal forpositive sealing.
The OmniSeal RP II, Page 22, is avery rugged design for severeoperating conditions. This sealutilizes a unique wrapped andformed stainless steel ribbon springwhich is highly resilient with widedeflection capabilities. Its durablespring and rugged jacket designmakes the OmniSeal RP II an excel-lent choice for heavy-duty sealingapplications and long wear life.
The Spring Ring II, is an economical alternative to theOmniSeal 400A for high productionapplications requiring low cost, small size seals. It is manufactured byautomated methods and is offered only in a limited number of sizes3 to 25 mm I.D. Design and sealing characteristics are similar tothe OmniSeal 400A.
Radial Sealsin Rotary MotionAll of the OmniSeal designs can beused in slow to moderate speedrotary or oscillatory applications atlow pressure.
In rotary shaft applications theflanged design is preferred.The flange is clamped in thehardware to prevent the seal fromturning with the shaft. This cansometimes occur with the standarddesigns due to thermal and othereffects. The flange provides positivehardware retention.
The flanged OmniSeal 400A, page 18,and the flanged OmniSeal APS onpage 15 are recommended for mostrotary/oscillatory applications.The light spring load minimizesfriction, at pressures under 1,5 MPa,with surface speeds in the range of1-1,5 m/s. At higher pressures,reduced surface speeds are requiredto prolong seal wear life. The resilient400A and APS spring allows for minorshaft runout or misalignment.
For very slow speeds, under 0,5m/s. and intermittent rotary/oscillatory motion at higherpressures, the flanged OmniSeal103A, Page 16 and OmniSeal RP II,Page 22, are recommended.The OmniSeal RP II has a veryresilient spring that can tolerateabove normal shaft run-out andmisalignment.
For applications requiring ultra-lowfriction, high pressures or highsurface speeds we suggest thatyou contact our Technical Support.(See inside back cover for completeinformation.)

Face Seals-Seal Function and Motion
Face Sealsin Static Service
The OmniSeal 103A, face seal is generally the first choice for most staticface seal applications. This series utilizesa moderate to high load spring, and iscapable of sealing effectively over awide temperature and pressure range.
Because of its very high springloading, the OmniSeal RACO®
1100A, is particularly recommended forextreme sealing conditions, cryogenictemperatures, ultra-high vacuum andpositive sealing of helium and otherlight gases.
The OmniSeal 400A, may also be used as a static face seal when lightspring loading is essential. However, its sealing ability may not be aseffective under extreme conditions aspossible with the 103A or the RACO1100A due to the relatively light spring load.
Face Sealsin Dynamic Service
OmniSeal 400A, is recommended forrotary face seal applications at slowto moderate rotary speeds. Lowspring loading keeps friction to aminimum. For ultra-low friction orhigh surface speed contact thefactory.
The OmniSeal APS, is an ideal choicefor use in dynamic reciprocating androtary applications. Due to the flatload curve of the Advanced PitchSpring (APS), it also providesexcellent service in friction sensitiveapplications.
In oscillatory or slow, intermittentrotary applications where highrotational torques are available,the OmniSeal RACO 1100A, isrecommended. Such applicationsinclude swivels and loading arm pivotjoints. Because of its exceptionallyhigh spring load, the OmniSeal
RACO 1100A is also an excellentchoice when maximum sealability ismandatory in liquids and gases with alow specific gravity and sealing atcryogenic temperatures.

Installation
Unlike Rubber O Rings, OmniSeal Sealsdo not stretch without damage.Therefore it is desirable to installOmniSeal spring energised seals inopen groove designs. If closed (non-split) or half open grooves areinevitable then make sure that, evenmore than with open grooves, all partsin touch with the seal when assembledare free from scratches and sharpedges. Otherwise the seal may bedamaged.
Assembling seals in closed grooves,located piston-wise will be easier thanbore-wise assembling. Piston-wiseassembling means the seal has to be
stretched. Depending on the diame-ter this stretching can be done byheating up the seal, so that naturalexpansion will reduce the elongationneeded to bring the seal in thegroove. When cooling down againthe seal will shrink back to the nomi-nal size.Bore-wise assembling means the sealhas to be deformed, and special careshould be taken when pushing theseal in the groove.
OmniSeal 103A, 400A and APS typeseals can be installed in closedgrooves. It is not recommended toinstall small diameter type 400A (U-spring) seals in closed grooves.
Bigger diameter seals are typicallyeasier to install in closed groovesthan smaller sized seals. Consult factory for seals diameterssmaller than 20 times the seal cross-section. Saint-Gobain Performance Plasticscan assist you with special assemblytools.
FrictionFriction, a measurement of theresistance to sliding between a sealand hardware surfaces, is directlyrelated to seal material coefficient offriction and the normal load. Someother factors affecting friction arelubrication, temperature andhardware surface finishes. Anapproximate friction value fornon-lubricated conditions can be
calculated using the charts andformulas on this page. Lubricationprovided by the media mayproduce lower friction results.
It is difficult to predict how therunning and break-out friction valueswill differ without testing underactual existing conditions. SGPPLmanufacturers a variety of springs
with lower or higher loads thanshown on this page. Also, specialsprings can be developed whenrequired.
For assistance with applicationswhere friction is critical.Contact our Technical Support.(see inside back cover for completeinformation.)
The approximate total load of an OmniSeal canbe calculated by adding the pressure load foundin the chart above to the average spring loadshown in the top chart.
Rotary MotionUse the chart above to qualify OmniSeal seals forcontinuous rotary applications.

In general, seal jacket materials become some-what harder at cold temperatures and tend tosoften to some extent at high temperatures(see material list on Page 14 for temperatureranges). The spring energiser compensates forthese conditions. If your seal design selectiondoes not agree with the graph (right), contactour Technical Support. (see inside back coverfor complete information.)
Seal Design Vs. Temperature
When sealing high pressures and/or hightemperatures, the size of the extrusion gapbehind the seal becomes critical.This extrusion gap is the clearance between thehardware members. Hardware designs withoutbearing or centering devices must consider thediametral clearance as the maximum extrusiongap. The combination of high pressures and/orhigh temperatures, excessive clearance can allowthe seal jacket to extrude into the gap causingpremature failure.
The extrusion gap should be held to theminimum, and should not exceed the valuesshown in the table(right). Increasingthe heel thicknessof the sealimproves resist-ance to extrusion.Also, the extrusiongap can be bridged by the use of a separateback-up ring arrangement.
Generally, the back-up ring should be of aharder material than the seal material. A highfilled PTFE compound, or a high modulus plasticsuch as A22, is recommended. See materialsshown on page 14. Additional back-up ringdetails are shown on Page 12.
Cryogenic Sealing
Cold temperatures below -40˚C will cause PTFEand other polymer sealing materials to shrinkand harden. These additional forces maycompromise the spring load and frictionalcharacteristics of the OmniSeal.
Although face seals are less affected than radialseals, we recommend consulting our SealTechnical Support team before selecting anOmniSeal for any cryogenic application.

The finish of the surface over whichthe OmniSeal must slide greatlyinfluences the relative wear of thecover material. Mating surfaces thatare too rough can create leak pathsand be abrasive to the seal.
The transfer of a thin film of PTFEfrom the OmniSeal cover to themating dynamic surface will improve
seal life. Dynamic surfaces withrelatively rough finishes wear thejacket material too rapidly. Extremelysmooth dynamic surfaces result ininsufficient material transfer to form athin film. The graph below illustratesthe effect of surface finish on sealwear.
Static Hardware Surfaces
In most static sealing applications,better overall sealing performance canbe achieved with a smoother sealingsurface finish. With OmniSeal therecommended optimum surface finishfor most static sealing applications is0,8 Ra or better. The “lay” onsurfaces for static face seals mustbe concentric.

Dynamic HardwareSealing Surface Hardness
As a general rule, the higher thesealing surface smoothness the better the overall seal performancecan be expected. Better smoothnessreduces wear and increases seal life. A 40 Rockwell C or greater isrecommended for slow to moderatereciprocating motion.
The ideal hardness is 60 to 70Rockwell C. Hardness in this range isrecommended for moderate to highspeed linear or rotary motion. Hardanodized surface must be polishedafter anodizing.
Gland Design
Consideration of proper glandgeometry in the early stages of designcan eliminate unnecessary installationproblems.
The use of split or separable glandsin piston and rod seal applications isalways desirable to eliminate stretch-ing or compressing the OmniSeal during installation into the gland.Split glands also eliminate the needfor special installation tools.
To minimize stretching or distortionduring assembly in non-split glands,the gland side wall on the pressure
side can be reduced to provide a partial shoulder to retain the seal.
If stretching into a full groove isunavoidable, consult our technicaldepartment. (see inside back cover)Assembly of the seal over sharpcorners, threads, keyways, etc.,should be avoided, or protectivetooling should be used when theseconditions exist.

Rectangular Back-Up (fig. 1)In most applications with lower pressureand temperatures below 250° C, a rectan-gular backup will secure the seal for extru-sion. Such backup rings are machined to fitexactly in the radial groove width. Thematerial should be a compound with ahigher extrusion resistance then the seal’smaterial.
Triangular Back-Up (fig. 2)In some cases where a high temperatureprecedes a high pressure it is recommendedto use a triangular backup.
Double Triangular Back-Up closing theextrusion gap and preventing extrusionof the seal. (fig. 3)
For extreme high pressure and temperaturecombinations it is recommended to use aset of two triangular back up rings. It is veryimportant to assemble the 90° corner of thebackup ring towards the extrusion gap. Thistype of backup ring is often used when theradial groove dimension changes as a resultof the system pressure.
L-shaped Back-Up (fig. 4)The L-shaped backup ring is used for pre-venting extrusion at extreme high pressureand high temperature combinations. It iscapable of securing PTFE seals up to + 300°C and extreme pressures, such as 20 MPa, with very large extrusions gaps.
Extrusion is a function off a) the size of the extrusion gapb) the temperaturec) the system pressured) surface speed (reciprocating movements)
Under pressure the PTFE tends to flow into the extrusion gap. Dynamicreciprocating movements increases extrusion. Under static conditionshowever and when pressure, temperature and extrusion are belowcertain limits, extrusion will stop as soon as the friction in the extrusiongap equals the pressure. Cycling conditions however can cause theextrusion to continue, resulting in premature failure of the seal.

Radial Seal
The OmniSeal 103A is a refinement ofthe original spring energised seal design.The helical wound flat spring offers amoderate to high spring load for staticand slow to moderate speed dynamicsealing. It has higher friction than the400A Series, but better sealing of lightliquids and gases. Available in all aero-space, military and industrial gland sizes.
OmniSeal type 103A is generally used forstatic applications and when positive seal-ing is most critical. Its relatively highspring load allows excellent sealing onsmooth surfaces and satisfactory sealingon rougher surfaces. The standard springload averages 5 N/mm circumference, butmay be tailored from less than 5N up to20N/mm circumference, to suit specificsealing specifications. Typically, high loadsare required where extremely low leakrates are necessary, as in the sealing ofcryogenic gases.
The 103A seal can also be successfullyused in slow dynamic applications, bothfor radial or face seal type applications.(see page 24-25 for face seal info).The largest possible cross section shouldbe selected, especially where applicationtemperatures are in the extremes.

OmniSeal type 400A has been designed for dynamic applications and therefore typi-cally features a lower load spring. In orderto obtain the best possible sealing perform-ance, mating surfaces must have asmoother finish than required for type103A seals. Static surfaces should also havea smooth finish to accommodate the lowerload spring performance. The standard spring load averages 1,5N/mm circumference, but can be tailoredto higher and lower loads. Such loads maybe required for extremely low frictionvalues or for enhanced sealing integrity atslower dynamic speeds.The 400A seal is also the preferred seal forHigh Temperature/High Pressure applica-tions. The largest possible cross sectionshould be selected, particularly whereapplication temperatures are in theextremes.Also available in face seal design.

Radial Seal
OmniSeal APS (Advanced Pitch Spring) utilizes a unique coiled wire spring designthat has a light load and characteristics of a wide range of deflection while producingan almost constant spring load. This featurepermits a large wear allowance in the sealjacket while maintaining an effective sealingload. Also, the spring can be wound inextremely small coil diameters, which makesthis type of seal ideal for small cross sectionand small diameter seal applications. Thelow stressed spring makes it possible todeform the seal, allowing for assembly ofrod seals into most closed glands withoutdamaging the spring.

Design Capabilities
For more than 30 years SGPPL hasdedicated its engineering efforts tosolving difficult and unique sealingproblems. With each challenge wegained greater insight into thescience of specialized sealing.
Today, aided by advanced 3-Dmodeling software and the latest
visualizing innovations, our teamof skilled design engineers isexploring the next generation ofsealing applications. Utilization ofFinite Element Analysis (FEA) as aviable design and production toolfacilitates higher productivity,design confidence, reduction in test-ing time and resultant cost savings.
Diaphragm SealsThis design combines a flexible diskand static face seal in a single unit.Diaphragm seals offer chemicalequipment designers a simple yetadvanced method for handlingcorrosive fluids in actuating valvesand small metering pumps.
Machined Spring Face SealThe machined spring seal is a solidring of metal covered by a thin PTFEjacket. The solid spring is imperme-able to light gases like hydrogen andhelium, and provides extremely lowleak rate sealing. It is also an excellentface seal for sealing hard vacuums.
Integral Piston SealFor small diameter applications atmoderate pressures, the integralpiston seal is an innovative approachto reducing the number of precisionmachined metal parts and compo-nents. In addition to being easy toassemble, this design serves as a sealand as a guide bearing.
Anti-Blowout SealThis unique design has been used inthe valve industry for over 40 years.In applications requiring the rod todisengage from the seal, theanti-blowout design prevents thedynamic sealing lip from deformingunder pressure.

Belleville Spring SealsFace seals energised with bellevillewashers provide high deflectionwithout risk of the spring collapsing.Another advantage of bellevilles isthat they can be manufactured insmaller diameters than most spring-energised seals.
Bi-Directional SealsThis versatile design combines twoseals and a guide bearing into aone-piece component. Thebi-directional seal is found in moderatetemperature/pressure applicationswhere simple assembly and quickreplacement are required. Whendesigned without an inside diameter italso serves as a floating piston.
