WAVIN MUFA 20 PEXAL TIGRIS M5 connector — model 4063972

WAVIN MUFA 20 PEXAL TIGRIS M5 connector — model 4063972 is a mechanical coupling designed for use with PEXal/Tigris multilayer pipe systems. The coupling is intended to join, repair or extend 20 mm piping runs in potable water and heating installations where PEXal/Tigris compatible fittings are required. The MUFA 20 configuration and M5 thread type provide a reliable pipe-to-pipe connection for domestic and light commercial plumbing tasks.

Advantages

The connector offers a compact, mechanically secure joint suitable for multilayer PEXal/Tigris pipes. Its construction supports quick installation without the need for specialized welding or adhesive methods, reducing downtime during repair or extension work. Designed for potable water and heating systems, the coupling maintains flow integrity and is compatible with standard 20 mm PEXal/Tigris system components.

Suitable for

• Repairing leaks or damaged sections in 20 mm PEXal/Tigris pipe runs
• Extending existing 20 mm potable water distribution lines
• Joining pipe segments in residential heating circuits using PEXal/Tigris
• Temporary or permanent mechanical connections in renovation projects

Key specifications

• Compatible pipe system: PEXal / TIGRIS multilayer pipes
• Connection diameter: 20 mm nominal
• Thread type: M5 mechanical thread
• Application media: potable water and heating circuits
• Function: mechanical coupling for joining, repairing, extending pipes

How to use

Prepare pipe ends by cutting squarely and removing any burrs or debris to ensure proper seating. Slide the connector into place and engage the M5 threaded components as required by the system instructions to create a secure mechanical joint. Verify alignment and tighten according to recommended torque or hand-tightening practice for PEXal/Tigris fittings. After installation, pressurize the system and inspect the joint for leaks before returning the installation to normal operation.

Usage recommendations

Use the connector only with compatible PEXal/Tigris multilayer pipes of the specified 20 mm diameter. Follow relevant local plumbing codes and manufacturer guidance regarding installation tools, torque settings and system pressure testing. For installations in heating systems, consider system flushing and appropriate antifreeze or inhibitor products where required by the application.
