How to use
Prepare the PP‑R pipe ends by cutting square and removing burrs. Clean the pipe and fitting surfaces, then use the appropriate PP‑R welding tool to heat both the pipe and the reducer ends to the recommended temperature. Insert the pipe into the fitting and hold until the joint cools and solidifies to form a homogeneous fusion connection. Follow tool manufacturer instructions and common plumbing practices for proper weld times and pressures.
Usage recommendations
Use certified PP‑R welding equipment, verify pipe and fitting compatibility, and avoid mechanical stress on the joint during cooling. Observe operating temperature limits (up to 90ºC) and applicable local plumbing codes when installing.
