What is 16mm MLCP Pipe?
MLCP stands for multilayer composite pipe. It is designed to combine the flexibility of plastic pipe with the strength and dimensional stability of a metal layer.
16mm MLCP pipe is commonly used in heating and water systems because it is easy to handle, suitable for neat routing and compatible with a wide range of press fittings when the correct system and profile are used.
Common Uses for 16mm MLCP Pipe
- Central heating pipework
- Underfloor heating installations
- Wall heating systems
- Hot and cold water pipework
- Chilled water and cooling applications
- Retrofit plumbing routes where flexibility is helpful
- Connections to manifolds, valves, copper pipe and threaded fittings using the correct adaptors
Why Installers Choose 16mm MLCP Pipe
- Flexible pipe structure makes it easier to route around obstacles.
- Multilayer construction helps provide strength and stability.
- Smooth internal surface can support efficient flow.
- Oxygen barrier options help protect suitable closed heating systems.
- Insulated and non insulated coil options are available.
- Press-fit fittings can help create fast, clean and consistent joints.
- Compatible tools and calibration accessories help prepare pipe ends properly before fitting.

Installation Tips for 16mm MLCP Pipe
- Always use pipe and fittings from compatible systems.
- Check whether the fitting requires U Profile or TH Profile jaws before pressing.
- Cut the pipe cleanly and square before preparing the end.
- Use a calibration tool where required by the system.
- Avoid kinking the pipe during bends. Use a bending spring where needed.
- Check pipe depth, fitting alignment and jaw placement before pressing.
- Pressure test the installation according to the relevant system guidance.
