## Summary description

Straight coupling made of PPSU by TECE, designed for 25 mm pipe connections. This pipe fitting provides a mechanical joint between two pipe segments of the same diameter and is suitable for plumbing installations where PPSU material is required for chemical and temperature resistance. Use in water distribution, heating circuits or sanitary systems requiring durable polymer couplings.

## Long description

The TECE PPSU straight coupling for 25 mm pipes is a polymer pipe fitting designed to join two sections of pipe with identical outer diameter. Made from PPSU (polyphenylsulfone), the coupling offers chemical and temperature resistance suitable for potable water distribution, heating circuits and sanitary installations where a durable polymer connection is required. The compact straight design creates a mechanical joint that maintains flow continuity and alignment between pipe segments.
Advantages
The PPSU construction provides high long-term resistance to hydrolysis and common plumbing chemicals, while retaining mechanical strength at elevated temperatures. The straight coupling ensures a secure, leak-resistant connection when installed according to the pipe system's joining method. Its geometric profile supports straightforward alignment and minimal flow restriction, and the polymer construction reduces risk of corrosion compared with metallic fittings.
Suitable for
 Potable water distribution systems
 Domestic and commercial heating circuits
 Sanitary and bathroom installations
 Environments requiring chemical-resistant polymer fittings
Key specifications
 Material: PPSU (polyphenylsulfone)
 Connection type: straight coupling for same-diameter pipes
 Pipe size compatibility: 25 mm outer diameter
 Application: water distribution, heating, sanitary systems
 Design: compact straight profile to maintain alignment and flow
How to use
Select pipes with 25 mm outer diameter and prepare pipe ends according to the system manufacturer's instructions (cut square, deburr and, if required, clean). Insert each pipe end fully into the coupling until it seats; follow the specific joining method recommended for the TECE system in use (for example, push-fit or with retaining elements where applicable). After joining, inspect the connection visually and perform a pressure test of the installation in line with local plumbing standards to verify leak-tightness.
Usage recommendations
Use this PPSU straight coupling in systems designed for polymer fittings; avoid exposure to solvents or aggressive chemicals not compatible with PPSU. Store fittings in a dry, UV-protected area prior to installation. Adhere to temperature and pressure limits specified by the overall piping system and follow TECE installation guidance for optimal performance.
