Continue pumping the handles until the jaws close and cut all the way through the pipe and you’re done! Our Irish compression fittings are made of brass bodies and olives. These are for use with Irish copper pipes. Squeeze the handles again and let the cutting jaw bite into the pipe. Make sure before you do this that the cut is in the correct point. Tapered Rubber Seal: This is pretty much the core part of the system – the tapered part of the seal pushes into the gap against the main compression body which also pushes in on the pipe holding it firmly in place and creating a seal between the pipe and the compression unit body preventing any leaks 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

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. Compression waste conversion bend. This bend allows you to change direction and convert from 40mm pipework to 32mm pipework and vice-versa The T-joint comes in a range of different sizes and fittings, both 32mm and 40mm, imperial and also reduction. Most commonly used when teeing into an existing pipe run Compression waste adjustable bend taking two pipes of the same size (32 or 40mm) round from a straight line up to 90 degrees. Again, invaluable in a conversion or renovation situationPlastic Washer: Once the below screw cap is screwed up it applies pressure to the washer which in turn presses down on the rubber seal, holding it in place and ensuring it seals Flexible waste straight coupling allowing you to join two pipes from 38mm to 45mm and absolutely ideal in a conversion or renovation situation. This fitting is also available to convert from 30mm to 38mm and can be bought as a flexible bend from 40mm to 48mm 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. 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 fittings Whilst cutting, keep your eye on your line and ensure the saw stays straight and true. Keep going until you are all the way through.

Similar to our imperial fittings range, our selection of metric fittings includes elbows, olives, straight couplers, and tees to be used on LPG. Before you can actually fit a compression fitting you will most probably need to cut a section of pipe to the correct length for your needs. There are really only a couple of ways that this can be done, considering the size of the pipes (e.g. 32mm an upwards): 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.Our lead fittings collection includes brass compression coupling for joining lead pipes to copper tubes. The fittings in this range are not suitable for gas use. Screw down the cap. Take your time while doing this and keep your eye on the seal and washer making sure they do not twist and that all is flush with the main body and pipe. Screw up until it starts to go tight and then give it one final pinch to create your water tight seal Now comes the rubber seal. Again, make sure that the taper is pointing in the right direction so that it slots into the main body of the compression joint. Ensure that it is not twisted and that it sits flat on the body of the pipe 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

Compression Waste Unit: In this case, this part is a 90° bend but can come in many different shapes. Made of solid plastic, it forms the main body of the compression joint Whether you need DZR fittings for commercial or residential construction, our collection includes adaptors, couplers, elbows, connectors, tees and stop ends designed for use in applications that deliver water consumption.Due to the size of pipe you are cutting (32 or 40mm), you will need to get some of the shear-type cutters. 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. Screw Cap: The final piece of the puzzle, this holds everything in place and ensures that the rubber seal provides a complete seal between the pipe and the main body At this point, position the pipe so that the top cutting jaw is directly over the mark on the pipe, or just to the side if you have marked the cut point exactly on the line.

Pump the handles which will operate the jaws of the shears and start closing them. As this is a ratchet system, one pump on the handle will close the jaws 10mm or so. Do this until the top cutting jaw is about 1mm off of the top of the pipe.

Assembling a Plastic Waste Compression Unit

Firstly, mark the exact point on the pipe that you need to make your cut, use a thin soft pen or felt tip. Remember, when marking the cutting point, if you make your mark at the exact length you will need to cut past the marking, leaving it on the pipe as otherwise your cut will be a millimeter or so too short! Compression fittings consist of three parts: a nut, a ring and a seat. When the compression fitting gets tightened, it provides a watertight connection. Helping you find the right compression fitting A flexible fitting which will allow to you connect a 32 or 40mm pipe round a wide bend to another sized pipe If a connection breaks down and fails, they are easy to remove and refit with a new one whereas with solvent welded fittings you have to start cutting pipes which can get complicated 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.
