## Summary description

Reducer tee REHAU RAUTITAN PX in PPSU material, dimensions 40×20×40 mm.

Suitable for potable water and heating installations where PPSU fittings are required for mechanical strength and chemical resistance.

## Long description

REHAU Trójnik red PX 40-20-40 RAUTITAN PPSU reducer tee 40×20×40 mm is a three-way plumbing fitting made from high-performance PPSU (polyphenylsulfone). It provides a transition between two larger 40 mm pipes and a reduced 20 mm branch, designed for use in potable water and heating systems. The fitting is produced by REHAU and matches RAUTITAN PX installations, offering mechanical strength, chemical resistance and long-term dimensional stability in typical building plumbing environments.
Advantages
The PPSU construction delivers improved impact resistance and temperature tolerance compared with standard thermoplastics, while resisting corrosion and common water-borne chemicals. The reducer tee enables a compact, reliable junction with smooth internal flow paths to reduce turbulence and pressure loss. Manufactured to fit RAUTITAN PX system geometry, the component ensures consistent joint quality and compatibility with corresponding pipe and connection technologies.
Suitable for
Domestic and commercial potable water distribution systems
Heating and radiator branch lines in hydronic systems
Plumbing installations requiring a reduction from 40 mm to 20 mm
Renovation projects where PP SU fittings are specified for chemical or thermal demands
Key specifications
Material: PPSU (polyphenylsulfone) — high temperature and chemical resistance
Configuration: reducer tee with two 40 mm ends and one 20 mm reduced branch
Connection compatibility: designed for RAUTITAN PX piping geometry and joining methods
Application temperature range: suitable for typical potable water and heating temperatures (refer to system design limits)
Flow characteristic: internal smooth contours to minimize pressure losses at the junction
How to use
Install the reducer tee according to RAUTITAN PX system instructions and local plumbing codes. Prepare pipe ends by cutting squarely and deburring, then fit pipes into the corresponding 40 mm and 20 mm ports ensuring full insertion depth. Use the recommended joining method for RAUTITAN PX — follow manufacturer guidelines for press, clamp, or fusion joining as applicable. After assembly, test the installation at working pressure and temperature to verify leak-free performance before commissioning.
Usage recommendations
Store the fitting in a dry, shaded area before installation to prevent UV exposure. Do not exceed the maximum system temperature and pressure specified for RAUTITAN PX installations, and avoid using the part with aggressive fluids that are not compatible with PPSU. For optimal lifespan, follow routine inspection and maintenance practices for plumbing and heating systems.
