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

Compression Fittings (COMP) Compression fittings
use a nut and olive (copper,brass or rubber
compression ring) to make a water tight seal
between the fitting and the pipe. All pipes used
must be clean and free from burrs before
assembly. A suitable sealing paste should also be
applied before the joints are tightened using a
wrench or spanner. Do not over tighten as this
can lead to problems should the fitting need to
be removed

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.

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 come into 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). 1/2"12.7 mm 3/4"19.05mm 1"25.4 mm

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)
22mm x 15mm x 22mm Compression Tee
22mm x 22mm x15mm Hep2O 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.
