WAVIN reducer external PEXAL TIGRIT 25x16 mm model 4064184

WAVIN reducer external PEXAL TIGRIT 25x16 mm model 4064184 is an external pipe reducer designed for connecting 25 mm to 16 mm PEX-aluminum-PEX (PEXAL) pipes. Intended for potable water and heating systems, the reducer creates a reliable mechanical transition between different pipe diameters using TIGRIT connection technology. Its external fitting profile allows straightforward installation where a durable, compact reduction is required without altering system integrity.

Advantages

The external reducer provides a precise, leak-resistant connection when joining 25 mm and 16 mm PEXAL pipes. Constructed to meet plumbing and heating system requirements, it supports potable water and circulation systems while maintaining mechanical strength at the joint. The TIGRIT connection method ensures consistent compression and a secure fit, reducing the need for additional sealing materials. Its compact design minimizes space usage and simplifies integration into existing piping runs.

Suitable for

• Reduction of PEXAL pipe diameter from 25 mm to 16 mm
• Domestic potable water distribution systems
• Central heating and radiator circuits using PEXAL pipes
• Renovation and new-build plumbing installations where space is limited

Key specifications

• Connection types: external PEXAL reducer for 25 mm to 16 mm pipes
• Compatible pipe system: PEX-aluminum-PEX (PEXAL) multilayer pipes
• Application: potable water and heating systems
• Installation method: mechanical TIGRIT compression connection
• Form factor: compact external reducer profile for reduced footprint

How to use

Prepare both pipe ends by cutting square and deburring the inner and outer edges. Slide the TIGRIT compression components as required, insert the 25 mm and 16 mm PEXAL pipe ends fully onto the respective connector ends, and complete the compression procedure according to TIGRIT tool and manufacturer instructions. Verify that the pipes are seated correctly and that the compression rings are engaged to form a secure mechanical seal. After installation, perform a pressure test of the system in line with local plumbing codes to confirm leak-tightness.

Usage recommendations

Use appropriate TIGRIT compression tools specified for PEXAL connections and follow local regulations for potable water and heating installations. Do not expose the reducer to mechanical stress beyond the piping system’s design loads, and ensure compatible pipe dimensions and wall thicknesses are used to achieve correct compression and long-term performance.
