How to use

Prepare the PE pipe by cutting it squarely and ensuring the end is free of burrs and debris. Insert the PE pipe into the fitting according to the manufacturer’s assembly method, securing it with the appropriate compression or insertion mechanism provided on the fitting.

Tighten to a suitable torque to achieve a leak-free connection without overstressing the threads or pipe.

Usage recommendations

Confirm compatibility of the fitting materials with the fluid and operating temperatures in your system. Use thread sealant or PTFE tape on metal threads where specified by local plumbing codes. Inspect connections after initial pressure testing and periodically during operation to ensure ongoing integrity.
