PE Pipe Compression Coupling

PE Pipe Compression Coupling

A straight connector keeps the water line on its existing route. It is a practical choice when extending a supply pipe, joining two prepared lengths or replacing a damaged section. Both ends accept the same selected pipe size, so check each pipe before ordering.

Choose the connection that fits your pipe

Measure the outside diameter of the polyethylene pipe and match it to the selected option. A pipe measurement is different from a threaded connection size, and a fitting that looks close may still be the wrong fit. The available options are 20 × 20 mm, 25 × 25 mm, 32 × 32 mm, 40 × 40 mm, 50 × 50 mm, 63 × 63 mm, 75 × 75 mm, 90 × 90 mm, 110 × 110 mm. For combinations with more than one dimension, confirm the size at each connection before purchasing. Plan enough space around the blue compression nuts so the joint can be assembled and inspected.

Prepare a clean, supported joint

Cut pipe squarely and remove loose debris from the cut end. Inspect the pipe surface where it will enter the fitting; a deep scratch or distorted end can interfere with a sound joint. Keep the pipe aligned with the socket and follow the supplied assembly instructions for insertion and tightening. Support nearby pipework so its weight does not pull sideways on the fitting.

Check the line before regular watering

After assembly, introduce water gradually and inspect every connection for seepage. Keep the joint accessible until the check is complete. Choose the fitting for the pipe material, size and operating conditions of your own installation, and confirm the permitted working pressure before connecting a pressurised supply. This fitting provides the stated connection geometry; it does not control watering flow or replace a shut-off valve.
