How to use
Prepare the pipe ends by ensuring they are cut square, deburred and clean. Insert the appropriate 28 mm and 15 mm pipes into each end of the coupler until they reach the designed stop, following the manufacturer’s guidance for insertion depth. Secure the joint by applying the recommended method for the specific system—this may include compression, push-fit, or soldering depending on the exact variant and installer practice. After assembly, pressurize the system and inspect the connection for leaks, making adjustments or re-seating as necessary to obtain a watertight joint.
Usage recommendations
Use with compatible pipe materials as specified for series 5000 fittings; verify system pressure and temperature limits before installation. For potable water applications, follow local plumbing codes and installation standards. When in doubt, consult technical documentation or a qualified installer to confirm correct installation method and suitability for the intended system.
