Hydroland Mufa 20 PEXAL (PX-RX.M.20) — pipe coupling for 20 mm PEX-AL-PEX

Hydroland Mufa 20 PEXAL (PX-RX.M.20) is a mechanical coupling for 20 mm PEX-AL-PEX pipes, created to join two sections of multilayer pipe in plumbing and heating systems. The coupling enables straight connections for repair, extension or new installations where a 20 mm diameter link between PEX-AL-PEX runs is required. Constructed for compatibility with 20 mm multilayer pipe, it provides a reliable, flush connection without altering pipe alignment when correctly installed.

Advantages

The coupling offers a compact design suitable for confined spaces and maintains the inner flow profile of the pipeline. Its mechanical joining method eliminates the need for soldering or specialized fusion equipment, enabling faster on-site work. The product is intended for use with PEX-AL-PEX multilayer pipe systems, providing stable axial and radial retention when assembled according to manufacturer instructions. Materials and dimensions are matched to 20 mm PEX-AL-PEX to ensure leak-resistant performance in domestic and light commercial applications.

Suitable for

• Joining two 20 mm PEX-AL-PEX pipe sections
• Repairing damaged runs in plumbing and heating circuits
• Extending existing 20 mm multilayer pipe networks
• Domestic hot and cold water distribution and underfloor heating manifolds
• Light commercial installations with 20 mm PEX-AL-PEX piping

Key specifications

• Compatible pipe type: PEX-AL-PEX (multilayer pipe)
• Nominal pipe diameter: 20 mm
• Function: straight mechanical coupling for pipe connection
• Typical applications: potable water supply, heating circuits, underfloor heating
• Installation environment: indoor plumbing and light commercial use

How to use

Cut both pipe ends square and deburr the inner and outer edges to ensure a clean mating surface. Slide the coupling components onto the prepared pipe ends and push until the pipe reaches the stop inside the fitting. Secure the mechanical connection following the manufacturer's assembly procedure, using the recommended crimping or compression tool for PEX-AL-PEX systems. After assembly, inspect the joint for correct alignment and perform a pressure test according to local plumbing codes before commissioning the system.

Usage recommendations

Use only with compatible 20 mm PEX-AL-PEX pipes and the appropriate crimping or compression tooling. Verify pipe dimensions and wall thickness to match the coupling. Avoid installation where continuous exposure to UV light or aggressive chemicals is expected. Follow local regulations for potable water and heating system installations and conduct pressure testing after fitting to confirm leak-free performance.
