Suitable for potable water and underfloor heating circuits when used with compatible PEXAL fittings; designed for reliable jointing and long-term service in building systems.

## Long description

WAVIN MUFA 25 PEXAL TIGRIS M5 is a mechanical coupling for PEX-A (PEXAL) piping systems with a 25 mm outer diameter. The fitting is intended to join two lengths of PEX-A pipe in domestic and commercial plumbing and heating installations. Designed to work with compatible PEXAL/Tigris components, this coupling enables secure, pressure-resistant connections suitable for potable water distribution and underfloor heating circuits when installed according to manufacturer guidance.
Advantages
The coupling provides a durable mechanical joint without the need for fusion tools, enabling faster on-site assembly. Constructed to meet the material and dimensional requirements of PEX-A systems, it ensures leak-tight performance under typical operating pressures for domestic water and heating loops. Its compact 25 mm size integrates easily into existing pipe runs and minimizes the space required for repairs or system extensions.
Suitable for
Joining 25 mm PEX-A (PEXAL) pipes in potable water systems
Connecting runs in underfloor heating circuits
Repairing or extending existing PEX-A piping installations
Domestic and light commercial plumbing and heating applications
Key specifications
Compatible pipe type: PEX-A (PEXAL) with 25 mm outer diameter
Connection method: mechanical coupling designed for PEXAL fittings
Typical application: potable water and heating circuits including underfloor heating

Size: 25 mm nominal pipe diameter coupling
How to use
Prepare the PEX-A pipe ends by cutting square and deburring to ensure a smooth insertion. Slide the coupling onto one pipe end, insert the second pipe fully into the opposite side, and verify correct seating and alignment. Tighten or secure the mechanical elements according to the manufacturer's instructions and any applicable installation standards. After assembly, perform a pressure test of the system to confirm a leak-free joint before putting the circuit into regular use.
Usage recommendations
Use the coupling only with compatible PEX-A (PEXAL/Tigris) pipes and fittings. Follow local plumbing codes and the fitting manufacturer's instructions for installation, including recommended tools, torque values, and pressure testing procedures.
