The aims of this slideshow are to:

Introduce the different types of fittings.Develop an understanding of different types and sizes of fittings.

The objectives of this slideshoware to ensure that students will be

able to differentiate between the following types of fittings:

End feedIntegral solder ringSpeed fitHep 2 OMale & female Iron fittings

And be able to correctly record a Tee fitting.

An Introduction to Common Plumbing Fittings

End Feed Fittings (E/F)

End feed fittings, are fittings where the solder is manually fed in from the end of

the fitting during soldering.

All pipes used must be cleaned and have flux applied to each joint before

heating with a blow torch and the application of solder

Integral Solder Ring (Yorkshire)

Yorkshire fittings (Yorkshire is a trade name) already contain a ring

solder inside them

All pipes used must be cleaned and have flux applied to each joint

before heating evenly with a blow torch until the solder is seen to melt

Speed Fit, HEP2O, Copper/Brass Push Fit

There are many different types of push fit joints are now being marketed,

they're available in plastic, brass & copper. There's not much difference

between them, they all incorporate some form of grip ring which creates a

seal between the pipe and the fitting and prevents the pipe from pulling

out. All pipes used must be clean and free from burrs before assembly.Insert the cleaned pipe into the fitting and push into place by hand.

Male Brass (MI) Fittings

Male Brass (MI) fittings have an external thread and are made as the

name suggests from brass.

These fittings are tightened using a wrench or spanner. Always use a

suitable sealing compound when assembling joints using these fittings.

Do not over tighten.

Female Brass (FI) Fittings

Female Brass (FI) fittings have an internal thread and are made as the

name suggests from brass.

These fittings are tightened using a wrench or spanner. Always use a

suitable sealing compound when assembling joints using these fittings.

Do not over tighten.

Fitting Sizes

Fittings are supplied in a variety of sizes ranging from 6mm through to

what ever size you require,although larger size fittings may have to be

specially ordered.

Generally the average plumber working in domestic properties will comeinto contact with fittings ranging from 6mm to 28mm.

As a plumber you will continue to come into contact with fittings still

measured in old imperial (inches). Some merchants catalogues will have

fittings still measured in inches especially internally or externally

threaded fittings as these are to BSP (British Standard Pipe).

Ordering Fittings 1

Ordering couplers is straight forward as they are the same size at both

ends (eg 15mm coupler)

Ordering tees is slightly more complicated. State the largest size first then

the opposite side and then the centre size (eg 22mm x 15mm x 22mm or

22mm x 22mm x15mm see examples below)

Ordering Fittings 2

What if all the sides of a Tee fitting are the same?

The Tee would simply be called an Equal Tee.

Other Fittings - Reducers

These are used when you need to reduce the pipe size e.g. 22mm cold

feed to a bath tap would then be reduced to 15mm to supply a basin tap,

not only is this more pleasing to the eye it is also more economical.

These fittings are used for capping off water supplies either temporally or

when permanently decommissioning.

The drain off is a valve located at the lowest point of any system and has

a serrated hose connection out-let.
