## Summary description

Straight reducing coupling TECE in PPSU for plumbing and piping systems, size 25 x 20 mm. Designed to join pipes of different diameters, this fitting provides a durable, corrosion-resistant connection suitable for potable water and heating installations. Compact metal-free PPSU construction ensures chemical and temperature resistance for reliable long-term use.

## Long description

Straight reducing coupling TECE PPSU 25 x 20 mm is a compact, metal-free fitting designed to connect pipes of different diameters in plumbing and heating systems. Made from polyphenylsulfone (PPSU), the coupling offers chemical and temperature resistance suitable for potable water and heating applications. Its reduction from 25 mm to 20 mm provides a reliable transition between pipe runs while maintaining flow integrity and long-term durability.
Advantages
The PPSU construction provides high resistance to chlorinated water, hot water and common plumbing chemicals while remaining dimensionally stable at elevated temperatures. Being metal-free, the straight reducing coupling resists corrosion and scaling and is lightweight compared with metal counterparts. Its compact design simplifies installation in confined spaces and supports a secure, leak-resistant joint when used with compatible push-fit or compression pipe systems.
Suitable for
 Reducing a 25 mm pipe run to 20 mm in potable water systems
 Hot water and heating circuit connections where a metal-free fitting is preferred
 Repair or modification of existing plastic piping networks
 Installations in confined spaces where compact fittings are required
Key specifications
 Material: Polyphenylsulfone (PPSU)
 Connection type: straight reducing coupling (25 mm → 20 mm)
 Application: potable water and heating systems
 Construction: metal-free, corrosion-resistant
 Temperature resistance: suitable for hot water use (refer to system design limits)
 Compact design for space-constrained installations
How to use
Before installation, ensure pipe ends are cut square, deburred and free of dirt. Select compatible 25 mm and 20 mm pipe materials and follow the pipe system manufacturer's recommendations for insertion depth and retention method. Insert the larger pipe into the 25 mm end and the smaller pipe into the 20 mm end until they reach the stop or the specified depth. Verify secure seating by checking for correct engagement and, if applicable, by performing a pressure test according to local regulations and system requirements.
Usage recommendations
Use this PPSU straight reducing coupling in systems designed for plastic fittings, avoid combining with dissimilar metals unless suitable isolation is provided, and always follow the installation and pressure/temperature limits set by the overall plumbing system and local codes.
