What is 20mm MLCP Pipe?
MLCP stands for multilayer composite pipe. It combines the flexibility of plastic pipe with the dimensional stability of a metal layer, helping installers create neat pipe runs with fewer joints.
20mm MLCP pipe is often used where a larger pipe size than 16mm is required, while still keeping the pipework flexible and easy to route through heating and water installations.
Common Uses for 20mm MLCP Pipe
- Central heating pipework
- Domestic hot and cold water systems
- Underfloor heating installations
- Wall heating systems
- Chilled water and cooling pipework
- Manifold feeds and distribution pipework
- Retrofit plumbing routes where flexibility is useful
- Connections from 20mm MLCP to 16mm MLCP, copper pipe or threaded fittings
Why Installers Choose 20mm MLCP Pipe
- Flexible multilayer construction helps make installation easier.
- Suitable options are available for heating, cooling and potable water systems.
- Coiled pipe can reduce the number of joints across longer runs.
- Insulated pipe options help protect pipework and reduce heat loss where suitable.
- Press-fit fittings help create clean, consistent and reliable joints.
- Reducers and transition fittings make it easier to connect to smaller pipe sizes or copper pipework.
- Clips, calibration tools and bending springs help support a tidy professional installation.

Installation Tips for 20mm MLCP Pipe
- Always confirm pipe, fitting and press jaw compatibility before installation.
- Check whether the product requires U Profile or TH Profile tooling.
- Cut the pipe cleanly and square before preparing the pipe end.
- Use a calibration or deburring tool where required by the system.
- Make sure the pipe is fully inserted into the fitting before pressing.
- Use pipe clips and supports to keep 20mm pipe routes secure and tidy.
- Avoid mixing systems unless the transition fitting is designed for that connection.
- Pressure test the completed installation according to the relevant system guidance.
