Product information

Description

REHAU RAUTITAN PPSU reducing tee 25-20-16 mm for plumbing connections is a three-way fitting made from PPSU (polyphenylsulfone) designed to join pipes of three different diameters in potable water and heating systems. The fitting creates a durable, corrosion-resistant junction between 25 mm, 20 mm and 16 mm pipes and is intended for professional installation in residential and commercial plumbing where reliable transitions between pipe sizes are required.

Advantages

The PPSU material delivers high mechanical strength, chemical resistance and long-term dimensional stability at elevated temperatures. The reducing tee provides a compact, leak-resistant connection between mixed-diameter pipelines and is suitable for repeated thermal cycles without significant deformation. Its smooth internal surfaces support stable flow characteristics and reduce the risk of sediment buildup over time.

Suitable for (use cases)

  • Connecting potable water supply lines with different diameters in residential buildings
  • Branching hot water heating circuits where size reduction is required
  • Plumbing installations in commercial facilities that require corrosion-resistant fittings
  • Integration into manifold systems and distribution networks with mixed pipe dimensions

Key specifications

  • Material: PPSU (polyphenylsulfone)
  • Connection type: reducing tee for three pipe diameters
  • Compatible pipe diameters: 25 mm, 20 mm, 16 mm
  • Application: potable water and heating systems
  • Temperature resistance suitable for domestic hot water and heating applications

How to use

Install the reducing tee by preparing the pipe ends according to the pipe system requirements—cut square, deburr and clean. Follow the REHAU RAUTITAN installation method and use the recommended joining technique for PPSU components, ensuring correct insertion depth and alignment of the pipes. After assembly, perform a pressure test in accordance with applicable local standards and repair codes before commissioning the system.

Usage recommendations

Do not expose the fitting to chemicals or conditions outside the material specifications. Use with compatible RAUTITAN pipes and recommended connection tools to ensure proper sealing and service life. Observe local regulations for potable water installations and carry out pressure testing after assembly.
