The Flexitallic Group is the internationalmarket leader in the manufacture and supply of high quality, high valueindustrial static sealing products, deliveringindustrial gaskets on a global scale.

Our extensive and varied productoffering includes spiral wound gaskets,RTJ gaskets, FlexproTM Kammprofiles,sheet materials, dynamic and staticpackings, pipe support and customrubber products. Drawing upon thegroup’s rich history and present dayvalues of leadership, quality, service and technology, we are at the forefrontof developing sealing solutions forindustries around the world.

In addition to a wide range of products,we also deliver world-class technicalsupport and Joint Integrity training.

About usAs the developer of the spiral woundgasket in 1912, we have built on thislegacy of innovation with revolutionaryproducts including Thermiculite® andSigma®, The Flange Rescue Gasket winnerof the NACE and Dupont Plunkett Awards,and most recently the ChangeTM Gasket, set to transform the global sealing industry.

We have a global network of AlliedDistributors across 30 countries. Thisensures local demand is met quickly,providing a combination of the highestproduct quality and outstanding customerservice.

FLEXITALLIC

Based on sales and geographic reach, the Flexitallic Grouphas become the global supplier of industrial gaskets.

Allied distributors

Inside IndustryWe pride ourselves on not simply supplyingproducts, but by supporting customers with a detailed knowledge of their industry andapplications, so that products and services are tailored to their specific needs.

This unique approach means that we focus onproviding more than just a product, but also acomplete solution that adds genuine value toour clients.

Global Distribution... Local SupportOur products are distributed through a globalnetwork of Allied Distributors.

These carefully selected distribution partnersare strategically located within their territoryto deliver the best possible service andproducts to our customers. This approachmeans our products and know-how areavailable to the global industries we service.

Innovative Product RangeWe have a rich history of innovation, which has seen us lead the industry with many newproducts.

Over the years, our products have gained areputation for quality, reliability and technologythat is second to none.

Customised Engineering SolutionsOur Application Engineering, ProductionEngineering and R&D teams work closelytogether to design, develop and manufacturebespoke sealing solutions.

We have been responsible for a number of trulyrevolutionary products, including Thermiculite®,Sigma® and the Flange Rescue Gasket, whichensure we are able to continually meet the evermore stringent requirements of our customers.

Flexitallic® SafeThe Flexitallic approach to safety is more than a program it’s a way of doing business thatstarted in 1912. We believe our commitment toinnovate, customize and educate adds anotherlevel of protection to our customers’ operations.

From the first Spiral Wound Gasket in 1912 tothe ever evolving applications for Thermiculite®,our goal is to develop materials that push theparameters of heat, pressure and chemicalresistance.

Our Commitment to QualityWe place great emphasis onmaintaining international qualitystandards, and are approved to ISO9001:2008, ISO 14001:2004 and OHSAS18001:2007, API 6A and API 17D, toensure we meet the highest possiblestandards for all our products andservices.

We also invest heavily in test and quality assurance equipment tomaintain our reputation for the highestquality products.

Our materials are subjected to a widerange of tests as specified by statutoryregulations and customer requirements.These approvals enable our customersto make informed choices as to thesuitability of a product for each andevery application.

For applications wherechemical resistance isparamount, SIGMA®

is the only option.

SIGMA®

Innovative Materials, Engineered SolutionsUtilising a unique manufacturing processexclusive to Flexitallic, SIGMA® representsthe latest generation of biaxially orientatedPTFE materials.

Specified by more than 500 majorcompanies, SIGMA® stands side by sidewith Flexitallic metal gaskets andThermiculite® gasket materials to provideyou with the complete and innovativesealing solutions you demand to handle all your sealing applications.

By designing seals that last longer in themost difficult applications, SIGMA® helpsproduction processes increase their outputcapabilities.

Total IntegrityWhen it comes to applications involvingaggressive chemicals, SIGMA® providesenhanced levels of sealing performancewhen compared to conventional materials.

While conventional PTFE-based sealingmaterials have long been the choice forsuperb chemical resistance, they are notideally suited to achieve the maximumreduction of creep in situations where seal integrity is paramount - a vitalconsideration for stringent long-termemission control.

Utilising a unique manufacturing processexclusive to Flexitallic, we createdSIGMA®, an innovatively-engineeredline of biaxially-orientated PTFE gasketmaterials.

Developed for processes ranging from cryogenic temperatures to 500oF(260oC), and suitable for sealing virtuallyevery chemical medium across the entirepH range (0-14), SIGMA® pairs theoutstanding chemical resistance of PTFEwith enhanced dimensional stability toimprove overall material stress retention.

The non-stick properties of the SIGMA®

range of materials offer excellent removalafter usage to dramatically reduce thedowntime on shutdown.

In addition, all components in theSIGMA® range are FDA compliant. This inherently clean nature makes themideal for use in industries where productcontamination is of concern such as food,pharmaceuticals and electronics.

Material Compliance and ApprovalsTUV, BAM, WRAS, FDA, DVGW.

For total sealing reliability, inventoryconsolidation and strict long-term emissioncontrol, nothing out-performs SIGMA®

– The innovation of integrity.
