How to use

Prepare pipe ends by ensuring they are clean, free of burrs and correctly cut to length. Fit the reducer over the pipe ends, ensuring correct alignment of the larger and smaller ends. Follow the chosen end-feed soldering procedure or the compatible connection method recommended for the piping system, applying appropriate flux and heat to form a reliable mechanical and leak-tight joint. Allow the joint to cool naturally before pressurising the system and inspect visually for correct penetration and secure seating.

Usage recommendations

Use the reducer with pipe materials and end-feed procedures specified by the piping system manufacturer. Confirm compatibility with local plumbing codes and pressure/temperature requirements. When working with soldering, ensure adequate ventilation and appropriate personal protective equipment. For installations in hard-to-reach locations, check accessibility and alignment before final joining.
