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 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 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 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.

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): 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 situation Our Irish compression fittings are made of brass bodies and olives. These are for use with Irish copper pipes. 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 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 leaksWhether 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

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. Continue pumping the handles until the jaws close and cut all the way through the pipe and you’re done! 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 Due to the size of pipe you are cutting (32 or 40mm), you will need to get some of the shear-type cutters.

Assembling a Plastic Waste Compression Unit

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

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.

What is a compression fitting?

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. Plastic 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

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 jointDespite the above minor disadvantages, push fit plastic compression wastes do have many advantages that can be seen below: Assembly of the unit is pretty straight forward. If you have several sections of pipe to put together it’s best to get it together on a bench or open space if you can, then insert it into it’s final resting place in one piece and slot together the final sections. Assembly is as follows: 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.
