Compression fittings are made mostly to use with 32mm or 40mm pipe work or to provide a conversion between two different sizes e.g. joining a 32mm pipe to a 40mm pipe. In most situations, you don’t need to screw the cap up too tight for it to provide enough pressure to create a seal. They are designed to be done up using hand pressure only so no grips or pliers are needed. A compression fitting is used to join two tubes or pipes or a pipe to a fixture or valve without soldering. They are preferred when installing cold or hot water pipes or repairing gas or central heating systems.

An important point to mention is that if you do tighten it too much this can damage the rubber seal or push it past the point of creating a good seal and leaks will start. In this case you will need to take it all apart and replace the seal if you can find an exact match or replace with a new compression unit if not. How to Cut Plastic Pipes for Compression Fittings Similar to our imperial fittings range, our selection of metric fittings includes elbows, olives, straight couplers, and tees to be used on LPG. Open up the shears to their full width and place the pipe on the base of the jaws. It does help to rest the cutters on bench or stable surface to support them and the pipe. One other really invaluable use for plastic compression plumbing fittings is when you are refurbishing and trying to join old pipes to new pipes including old lead wastes (which should be replaced if you get the chance) and odd sized imperial waste plumbing pipework, they are absolutely ideal for this Waste pipes used for push fit fittings and solvent weld fittings are two entirely different sizes and one of the easiest ways to join the two is by using compression fittingsOur Irish compression fittings are made of brass bodies and olives. These are for use with Irish copper pipes. Whether you need an adaptor, a coupling, a tee or an elbow, our stainless steel compression fittings collection is suitable for connecting pipes in natural gas and LPG applications. Experience is everything for us For those that are new to plumbing, compression fittings provide the ideal introduction as they are easy to fit and adjust To do this, use a fine piece of sandpaper, at least 280 grit or greater or a small file and gently run it around the edges until smooth – Don’t press too hard as you will scratch the pipe and this may cause leaks. Once done, the pipe is ready to fit.

No matter what your plumbing installation project involves, our large selection of brass compression fittings will have you covered, from elbows and nuts to tank and tap connectors.A compression straight coupling, joining two pipes of the same size in a straight line. 32mm and 40mm Whilst cutting, keep your eye on your line and ensure the saw stays straight and true.
