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

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.

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)

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.
