WAVIN TRÓJNIK PEXAL TIGRIS M5 20 x 1/2 in. 4064331 — plumbing branch fitting

WAVIN TRÓJNIK PEXAL TIGRIS M5 20 x 1/2 in. is a branch fitting engineered for PEX‑AL‑PEX (PEX‑aluminum‑PEX) Tigris systems to form a secure connection between a 20 mm pipe and a 1/2 inch threaded branch. It is intended for potable water and heating installations where a metric plastic-aluminum composite supply line must transition to an imperial threaded outlet. The fitting is designed to be installed in distribution manifolds, risers and branch lines to provide a compact, leak-resistant junction compatible with PEXAL piping practice.

Advantages

The fitting provides a stable mechanical transition between PEX‑AL‑PEX pipe and a 1/2 in. threaded outlet, reducing the need for additional adapters. Its design supports reliable sealing under typical operating pressures for domestic water and heating circuits. Using a dedicated PEXAL branch fitting simplifies installation in confined spaces and helps maintain system integrity when connecting metric piping to imperial-threaded fixtures or valves.

Suitable for

• Domestic potable water distribution where a 20 mm PEX‑AL‑PEX main supplies a 1/2 in. branch
• Underfloor heating manifold branches and radiator connections
• riser-to-branch transitions in multi-storey plumbing installations
• Connections to valves, fixtures or threaded adapters that require a 1/2 in. male/female thread

Key specifications

• Connection type: PEX‑AL‑PEX press/insert for 20 mm main with 1/2 in. threaded branch
• Material compatibility: designed for PEX‑aluminum‑PEX composite piping systems
• Application: potable water and heating distribution
• Installation locations: manifolds, risers, branch lines
• Sealing principle: threaded branch with appropriate gasket/seat for leak resistance

How to use

Prepare the 20 mm PEX‑AL‑PEX pipe according to the manufacturer's guidelines: cut square, deburr and verify correct insertion depth. Insert the fitting into the PEXAL main using the prescribed press or connection method for Tigris systems to obtain the required mechanical seal. Tighten the 1/2 in. threaded branch to the mating component using appropriate tools and sealing material where specified (for example PTFE tape or a gasket if required), ensuring not to overtighten. After assembly, perform a pressure test on the system in accordance with local codes to check for leaks before commissioning.

Usage recommendations

Use only connection tools and procedures recommended for PEX‑AL‑PEX Tigris systems and follow local plumbing regulations. Match thread type and sealing method to the mating component and perform a pressure test after installation to confirm leak-tight performance.
