Poly Pipe Fittings

Hansen Poly Pipe Fittings are easy to install. Follow our three step guide below. Tighten the fitting onto the pipe by winding the nut by hand as tight as you can. Then, whilst holding the pipe, you can use a spanner or a pipe grip to tighten further until the nut is firmly bonded to the pipe.

Step by Step Guide

Prepare Poly Pipe Step 1

Step 1: Cut the pipe and ensure that is is square. Clean burs off pipe. When repairing a burst pipe, ensure that the length of the cut-away matches the replacement fitting between the screwed on nuts.

Prepare Poly Pipe Step 2

Step 2: Ensure the nut is fully wound back onto the body of the fitting. Push the pipe onto the fitting and as far as possible into the nut.

Prepare Poly Pipe Step 3

Step 3: Wind the nut onto the pipe a few turns. Tighten with spanner or pipe grips.

Remember to allow some slack when laying the pipe to provide for expansion and contraction with temperature changes. The fittings are intended for domestic water and can be used in marine applications.

Don’t use them for pool water as the chlorine in swimming pool water (a halogen) will attack the material. Please read through the chemical compatibility list below.
