## Summary description

Straight reducing coupling by TECE in PPSU material, sized 25 x 16 mm (model 8710620). Designed to join pipes of different diameters in plumbing and heating installations, providing a corrosion-resistant plastic connection. Suitable for potable water and central heating systems where a reliable transition from 25 mm to 16 mm pipework is required.

## Long description

TECE straight reducing coupling in PPSU, size 25 x 16 mm, is a compact plastic fitting designed to connect pipes of different diameters in plumbing and heating systems. Made from PPSU (polyphenylsulfone), the coupling offers chemical and temperature resistance suitable for potable water and central heating installations where a reliable reduction from 25 mm to 16 mm is required. The fitting provides a corrosion-free alternative to metal couplings and is compatible with common plastic and multilayer piping systems used in residential and commercial projects.
Advantages
The PPSU construction ensures long-term dimensional stability and resistance to hot water, chlorinated water and many common plumbing chemicals. The straight reducing design enables a secure and leak-resistant transition between 25 mm and 16 mm pipes, simplifying installation and reducing the need for additional adapters. The compact form factor and smooth internal flow profile minimize pressure loss at the joint and contribute to reliable hydraulic performance.
Suitable for
Domestic and commercial potable water distribution
Central heating systems
Connections between different-diameter plastic or multilayer pipes
Repair and retrofit work where space is limited
Key specifications
Material: PPSU (polyphenylsulfone)
Connection type: straight reducing coupling
Nominal sizes: 25 mm to 16 mm
Application: potable water and heating systems
Temperature resistance suitable for hot water systems
How to use
Ensure both pipe ends are clean, deburred and cut square before assembly. Slide the coupling onto the 25 mm pipe end and then insert the 16 mm pipe into the other side until fully seated. Follow the pipe system manufacturer's instructions for insertion depth and any required securing method (such as crimping, pressing or push-fit verification) appropriate to the specific pipe type. After installation, perform a pressure test in accordance with applicable local regulations to verify joint integrity.
Usage recommendations
Use the coupling in systems within the manufacturer's recommended temperature and pressure limits; avoid exposure to aggressive solvents or oils not compatible with PPSU. For best results, use fittings and pipes from the same compatible system family and verify compatibility with potable water standards where required.
