We keep MDPE Pipe Fittings for every need here at EasyMerchant. They’re all WRAS approved and high in quality. They simply screw down and compress onto the pipework to create a water tight seal. Don’t forget to use pipe liners inside the pipe to stop leakage.

We pride ourselves on the quality of our fittings but also on our high quality of delivery service and after sales support.

MDPE Compression / mechanical fittings provide solutions for connecting PE pipes, used for conveying water and other fluids in inter-urban and urban infrastructure, industrial, mining, landscape, farming in addition to optical fibre duct systems. The fittings are designed to withstand working pressures of up to 16bar, and these fittings are manufactured in all common diameters.

How to Install MDPE Compression Fittings:

For Diameter Sizes 20-110mm

  • Insert liner into pipe (metric 20mm-63mm only) and slacken nut till half the thread is visible

  • Push MDPE pipe into the body of the fitting, through the nut, split ring, and ‘O’ ring

  • Tighten the nut firmly: Hand tighten onto the pipe

  • 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).

We also keep in stock The Universal transitional coupling. It is a great choice when it comes to joining MDPE pipe. These couplings are so versatile they can join virtually any run of pipe together.

How to Join MDPE Pipes:

The MDPE pipe needs to be cut squarely and cleanly, this can be done using a hacksaw but for a neater cut a dedicated plastic pipe cutter should be used. After cutting, the pipe ought to be de-burred before inserting the cut end into any fitting.

Most fittings require the use of a pipe insert for MDPE pipe. It's Vital that a pipe insert is used for all other types of joint as the joint could easily fail if the insert is omitted. The inserts stiffen the pipe to stop the compression fittings squeezing the pipe and causing leakage.

  1. Push the inserts into each end of the cut pipe

  2. Unscrew the caps from the coupler or bend of the compression fitting

  3. Remove the grab rings (if any)

  4. Put the unscrewed caps over each end of the pipe

  5. Push the pipe inside the compression fitting until it stops

  6. Pull the caps back toward the fitting over the pipe and tighten them.
