WAVIN TRÓJNIK RED 16x20x16 PEXAL TIGRIS M5 plumbing fitting

WAVIN TRÓJNIK RED 16x20x16 PEXAL TIGRIS M5 is a three-way plumbing fitting for PEXal/Tigris multilayer pipe systems. The reducing tee connects a 20 mm main run with two 16 mm branches, providing a compact solution for creating branches in heating and potable water installations. Designed to work with compatible WAVIN PEXal components, the fitting supports systems assembled with press or push-fit connection methods and is intended for domestic and light commercial piping.

Advantages

The reducing tee features a compact geometry that saves installation space and eases routing in service ducts and wall cavities. Manufactured to match PEXal/Tigris system dimensions, it ensures consistent internal flow paths and reliable mechanical connection when used with compatible press or push-fit fittings. The product’s design reduces the need for additional adapters when switching between 20 mm and 16 mm lines, simplifying inventory and installation steps.

Suitable for

• Branching heating circuits in residential systems
• Creating potable water branches from a larger mains line
• Repairs and retrofits where a size reduction is required
• Applications using press or push-fit connections compatible with WAVIN PEXal/Tigris

Key specifications

• Fitting type: reducing tee for multilayer PEXal/Tigris pipes
• Connection diameters: one 20 mm inlet/outlet and two 16 mm branches

How to use

Select the reducing tee sized to match the existing 20 mm run and the 16 mm branch lines.
