WAVIN plumbing reducing tee TRÓJNIK RED 25×20×25 PEXAL TIGRIS M5 (MPN 4064362)

WAVIN TRÓJNIK RED 25×20×25 PEXAL TIGRIS M5 is a reducing tee designed for use with PEX-aluminium-PEX (PEX-AL-PEX) plumbing systems. The fitting creates a branch from a 25 mm main run to a 20 mm branch while maintaining two 25 mm run ends, allowing compact and reliable distribution and branch connections in potable water and heating installations. The product is intended for use where a size transition is needed without compromising flow control and leak resistance.

Advantages

The reducing tee is manufactured for compatibility with PEX-AL-PEX pipes and provides a durable joint that resists corrosion and typical plumbing stresses. Its design ensures a secure, leak-resistant connection when installed with the correct compression, crimp or push-fit method suitable for PEX-AL-PEX systems. The compact configuration simplifies routing in distribution manifolds and underfloor or radiator circuits, enabling a smaller footprint at branching points.

Suitable for

• Domestic potable water distribution where a 25 mm main line requires a 20 mm branch
• Heating circuits including radiator and underfloor heating manifolds
• Plumbing installations using PEX-AL-PEX (PEXal) pipe systems
• Repair or modification work requiring a reliable size transition in supply lines

Key specifications

• Material compatibility: PEX-aluminium-PEX (PEX-AL-PEX) pipe systems
• Connection sizes: two 25 mm run ends and one 20 mm branch end
• Application: potable water and heating systems
• Function: reducing tee for distribution and branch connections
• Installation types supported: compression/crimp/push-fit methods compatible with PEX-AL-PEX

How to use

Prepare PEX-AL-PEX pipes by cutting squarely and deburring the pipe ends before assembly. Follow the pipe system manufacturer’s instructions for the chosen joining method (crimp, clamp, or push-fit) and use the correct-sized fittings and tools for 25 mm and 20 mm connections. Insert the pipe ends fully into the tee, secure each connection according to the selected method, and perform pressure testing per local plumbing standards to verify leak-free operation before concealing the installation.

Usage recommendations

Use only with compatible PEX-AL-PEX pipe types and approved jointing tools. Verify that operating temperatures and pressures for potable water and heating circuits are within the range permitted by the overall piping system. After installation, conduct a pressure test in line with applicable regulations and inspect joints for correct seating and sealing.
