## Long description

WAVIN coupling MUFA 16 PEXAL TIGRIS M5 is a mechanical coupling designed for joining 16 mm PEX‑AL (PEX‑AL‑PEX) multilayer pipes. The fitting is part of the PEXAL TIGRIS family and provides a secure, leak-resistant connection for plumbing and heating systems where a compact, straight coupling is required. It is intended for use with 16 mm PEX‑AL pipes in distribution networks, underfloor heating and repair or modification tasks.
Advantages
The coupling offers a reliable mechanical joint that maintains pipe alignment and ensures consistent hydraulic performance. Its compact design allows installation in confined spaces and behind fixtures. As a product from the PEXAL TIGRIS range, the coupling is compatible with common installation techniques for multilayer PEX‑AL pipes and supports rapid assembly with standard tools used for this system. The component reduces the need for soldering or adhesive bonding, simplifying maintenance and replacements.
Suitable for
 Connecting 16 mm PEX‑AL (multilayer) pipes in potable water distribution systems
 Underfloor heating circuits using 16 mm PEX‑AL pipe
 Repairing or extending existing PEXAL TIGRIS pipe runs
 Tight spaces behind radiators, manifolds or in service shafts
Key specifications
 Pipe compatibility: 16 mm multilayer PEX‑AL (PEX‑al‑PEX) pipes
 Type: straight mechanical coupling for pipe-to-pipe connections
 Material properties: corrosion-resistant construction suitable for potable water and heating media
 Installation: push-fit or compression type assembly compatible with standard PEX‑AL installation tools
 Application temperature: suitable for typical domestic plumbing and underfloor heating temperature ranges
How to use
Ensure pipe ends are cut squarely and deburred before assembly. Slide the coupling components onto the prepared pipe ends and engage according to the PEXAL TIGRIS assembly method: fully insert each pipe into the coupling until it seats against the stop, then complete the mechanical securing step required by the system (for example crimping or tightening per manufacturer instructions). Verify the connection visually and, where applicable, perform a pressure test of the section to confirm leak-free installation.
Usage recommendations
Use the coupling only with compatible 16 mm PEX‑AL pipes and follow manufacturer installation instructions and applicable local plumbing codes. For best results, use the recommended tooling for PEXAL TIGRIS fittings and perform a pressure test after assembly. Replace any damaged components and avoid exposing the fitting to prolonged direct sunlight or chemical agents not intended for potable water systems.
