Push-fit fitting
In plumbing
A fitting that joins pipe by pushing it in past an O-ring seal and a grab ring of small teeth that stop it pulling out again. It needs no heat or spanners, but the pipe end is cut square, deburred and pushed fully home, and plastic pipe takes an insert so that it keeps its round shape.
Using Push-fit fitting in a plumbing system
Updated
A distinction worth remembering
A leak-free connection can still be strained by unsupported pipework, movement or expansion. Revision should connect joint type, material, access and support to the service conditions. Installation details belong to the relevant system manufacturer's instructions and supervised training.
Questions to take further
- Does a joint that looks dry immediately prove the work is finished?
- No. Appropriate testing, inspection and checking the system under its intended conditions are part of the work. Access for maintenance and suitable support matter too.

A short sleeve pushed into the end of plastic pipe before it goes into a fitting. It supports the pipe wall from inside, so the seal or the olive presses against something firm. Leaving it out can let the joint weep or pull apart, and makers' instructions say when one is needed.

Pipe insert — Pipe stiffener
A short sleeve pushed into the end of plastic pipe before it goes into a fitting. It supports the pipe wall from inside, so the seal or the olive presses against something firm. Leaving it out can let the joint weep or pull apart, and makers' instructions say when one is needed.
Read the Pipe insert entryCompression fitting
A joint on water pipework made by tightening a nut over a ring called an olive, which squeezes onto the pipe and seals it. It needs no heat, which makes it useful where soldering would bring a fire risk, and it can be taken apart later. Too little tightening leaves it weeping, and too much can distort the olive.
Read the Compression fitting entryBefore you start: some plumbing work is regulated or notifiable
Some water fittings work needs notice to, and consent from, the water supplier before it starts. Check the rules where you live.
Gas work is for competent workers covered by a Gas Safe registered business in Great Britain. Northern Ireland has separate gas regulations. Do not work on gas pipes or appliances yourself.
In England, installing an unvented hot-water system over 15 litres is notifiable building work: use a competent installer registered with a competent-person scheme, or tell building control before work starts. Leave this work to a suitably skilled person.
Wales, Scotland and Northern Ireland have their own water and building rules; check which apply before work starts. Electrical connections belong with an electrician.
This guide does not qualify you or make you competent, approved or registered for plumbing, gas or unvented work.
A definition is a start. Using it in a real question is where it sticks.
