Composite press-fitting couplings join two compatible MLCP pipe sections in a straight line. They are useful for extending pipe runs, carrying out alterations or making planned connections where a continuous coil or straight length is not practical.
The coupling must match the pipe outside diameter, wall thickness and approved press profile. Do not assume that fittings from different multilayer systems are interchangeable simply because the nominal size is similar.
Both pipe ends should be cut square, calibrated, prepared and inserted fully before pressing. Use the correct jaw and support the finished connection so that movement or misalignment does not load the joint.
Browse the composite press couplings below and combine them with matching elbows, tees and MLCP pipe for reliable multilayer plumbing and heating installations. You may also find the related composite press elbows and MLCP pipe coils useful when completing the system.
