## Long description

WAVIN TRÓJNIK RED 20x16x16 PEXAL TIGRIS M5 is a three-way plumbing fitting designed for PEX-aluminum-PEX (PEXal) pipe systems. The fitting provides a compact branch connection that joins a 20 mm inlet to two 16 mm outlets using the TIGRIS M5 coupling system. It is intended for potable water and heating distribution and facilitates reliable transitions between different pipe diameters in manifold, branch or compact installation scenarios.
Advantages
The fitting is produced to work with PEXal pipe constructions and the TIGRIS M5 coupling standard, offering mechanical stability and dimensional compatibility. Its reduced-tee configuration allows space-efficient routing and branching where pipe diameters change. The design supports potable water systems and heating circuits, providing a durable connection that maintains flow performance while minimising the need for additional adapters.
Suitable for
Domestic potable water distribution where a 20 mm line branches into 16 mm lines
Underfloor heating and radiator circuits requiring diameter reduction at branch points
Compact manifolds and service closets with limited installation space
Renovation projects where integrating different pipe diameters is necessary
Key specifications
Connection type: three-way reduced tee for PEXal (PEX-aluminum-PEX) pipes
Sizes: 20 mm inlet, 16 mm outlets
Coupling system: TIGRIS M5 compatible
Application: potable water and heating distribution
Material compatibility: PEXal pipe systems and TIGRIS fittings
How to use
Ensure pipe ends are cut square and deburred before assembly. Fit the PEXal pipes into the TIGRIS M5 coupling points until fully seated according to TIGRIS installation guidelines. Verify alignment and secure the connections following the recommended tightening or securing method for the TIGRIS M5 system. After assembly, pressure-test the system according to local codes to confirm leak-free performance before commissioning.
Usage recommendations
Use with compatible PEX-aluminum-PEX piping and TIGRIS M5 couplings only; follow manufacturer installation instructions and local plumbing standards. Verify system pressure and temperature ratings for potable water and heating applications before use.
