High-Quality MDPE Pipe Liner – WRAS Approved.
Our range includes these extremely cost-effective MDPE pipe liners – designed to strengthen the pipe when using a compression type fitting.
What is an MDPE pipe liner?
A pipe liner fits into the end of a MDPE pipe – and has a lip on the end of the part to stop it over-inserting. When in place, the pipe liner prevents the MDPE pipe from being overly compressed and breaking – thus compromising the join.
Although MDPE is more supple that HDPE alternatives, it will still break if put under enough crushing pressure. The nature of compression fittings means it’s possible to do this – so it makes sense to insert a liner first, preventing over-tightening and saving the connection.
You will not find a single installation guide that doesn’t recommend the use of pipe liners in MDPE pipe – they’re an essential item for your tool box or van if you’re working with MDPE pipe.
The pipe liner sizes we stock are in line with the most common MDPE pipe sizes. The MDPE pipe liner sizes available are:

20mm (½”) – 32mm (1”), on pipe 40mm
(1 ¼”) and above use a compression fitting pipe wrench.
Note: For pipe diameters, 40mm and above, chamfering and lubrication of the pipe will be needed to help ease insertion of the pipe into the fittings. Use a silicon-based lubricant).
