## Long description

REHAU RAUTITAN PPSU straight coupling 25×25 mm — plumbing connector is a straight joining fitting designed for RAUTITAN piping systems. Manufactured from PPSU (polyphenylsulfone), this coupling connects two 25 mm pipes in potable water and heating installations. The product is intended for environments where chemical resistance, high temperature tolerance and long-term dimensional stability are required, offering a reliable mechanical connection for domestic and commercial plumbing systems.
Advantages
The PPSU material provides high resistance to heat, hydrolysis and many common chemicals, ensuring durability in hot water and central heating systems. The straight coupling delivers consistent dimensional accuracy for secure, leak-resistant joints and is compatible with RAUTITAN system components, simplifying installation and maintenance. Corrosion resistance and low thermal expansion contribute to long service life compared with some metal alternatives.
Suitable for
Joining two 25 mm RAUTITAN pipes in potable water supply lines
Connections in domestic and commercial heating circuits
Areas requiring corrosion- and chemical-resistant fittings
Plumbing systems where long-term dimensional stability is needed
Key specifications
Fitting type: straight coupling for two pipes
Material: PPSU (polyphenylsulfone)
Nominal pipe size: 25×25 mm
Application: potable water and heating systems
Properties: high temperature resistance, chemical resistance, corrosion resistance
How to use
Prepare both pipe ends by cutting square and deburring to ensure proper fit. Slide the coupling into position between the two 25 mm RAUTITAN pipes and secure according to RAUTITAN system instructions, using the appropriate pressing or connection method specified for PPSU fittings. Verify alignment and fully complete the jointing procedure recommended for the system, then perform a pressure test of the pipeline to confirm leak-free installation before commissioning.
Usage recommendations
Use the coupling only with compatible RAUTITAN components and tools. Observe manufacturer guidance for maximum operating temperature and pressure limits of PPSU fittings. Store fittings away from direct sunlight and extreme temperatures prior to installation. Regularly inspect visible connections during scheduled maintenance to detect any signs of wear or improper installation.
