## Summary description

PPSU reducer tee Uponor S-Press 20–25–20 (DWZ) is a press-fit plumbing fitting designed for joining three pipe runs with a reduced central branch. Made from PPSU for chemical and temperature resistance, it supports press connection installation using the S-Press system. Suited for potable water and heating systems where reliable, leak-resistant reductions between 20 mm and 25 mm pipes are required.

## Long description

Tee reducer PPSU Uponor S-Press 20–25–20 (DWZ) is a press-fit plumbing fitting designed to connect three pipe runs where the central branch has a reduced diameter. Manufactured from PPSU (polyphenylsulfone), this fitting provides chemical and temperature resistance suitable for potable water and heating installations. It is intended for use with the S-Press press system and creates a secure, leak-resistant joint between 20 mm and 25 mm plastic pipes.
Advantages
The PPSU construction offers high resistance to hot water, chemicals and mechanical stress while maintaining dimensional stability. The S-Press compatible design enables reliable press-fit installation without the need for soldering or adhesives, reducing installation time. The reduced central branch allows for smooth transitions between different pipe diameters, helping preserve flow characteristics and minimizing turbulence at the junction.
Suitable for
Potable cold and hot water distribution systems
Domestic and light-commercial heating circuits
Branching pipe runs where a 25 mm main must feed 20 mm branches
Installations requiring press-fit connections for speed and repeatability
When it may not be suitable
This tee reducer is not intended for use with metallic pipe systems or press systems incompatible with the S-Press connection geometry. It is also not suitable for applications that require larger diameters than 25 mm or bespoke fittings with non-standard branch angles. For systems exposed to aggressive solvents or competencies beyond standard potable water and heating chemicals, material compatibility should be verified.
Key specifications
Material: PPSU (polyphenylsulfone)
Connection type: press-fit (S-Press compatible)
Dimensions: main run 25 mm — branch 20 mm — opposite run 20 mm
Intended media: potable water and heating fluids
Temperature resistance: suitable for typical domestic hot water and heating temperatures
How to use
Prepare pipe ends by ensuring they are cut square, deburred and clean of debris. Mark insertion depth on the pipe if required by installation practice, insert the pipe fully into the fitting until the stop is reached, and perform the S-Press operation with a compatible press tool and jaw to form the permanent joint. After pressing, inspect the connection visually and, where appropriate, perform a pressure test according to local standards and project requirements.
What to consider before purchase
Compatibility with the S-Press press system and available press jaws
Pipe material and outer diameter accuracy for a secure press connection
Operating temperature range of the intended system
Compliance with local regulations for potable water and heating installations
Usage recommendations
Use with certified S-Press tooling and follow Uponor installation guidelines. Ensure pressure testing after installation and avoid using the fitting with incompatible chemicals or above recommended temperature limits.
