## Long description

REHAU RAUTITAN Trójnik red PX 25-16-16 PPSU is a reducing tee designed to join a 25 mm main pipe with two 16 mm branches. Manufactured from PPSU (polyphenylsulfone), this pipe fitting is intended for use in plumbing and heating systems where durability, resistance to high temperatures and chemical stability are required. The fitting provides a compact solution for branching potable water and heating lines while maintaining flow integrity between differing pipe diameters.
Advantages
The PPSU material offers high thermal resistance and durability, making the reducing tee suitable for repeated temperature cycles and long-term operation. The design ensures reliable hydraulic performance when connecting a larger 25 mm supply line to two 16 mm distribution lines. Its corrosion-resistant properties and dimensional stability minimize maintenance needs and contribute to a longer service life in water and heating applications.
Suitable for
 Branching a 25 mm main supply into two 16 mm lines in potable water systems
 Connecting heating circuit manifolds or local radiator feeds with mixed diameters
 Use in domestic and commercial plumbing installations where PPSU performance is required
Key specifications
 Material: PPSU (polyphenylsulfone)
 Configuration: Reducing tee (one inlet 25 mm to two outlets 16 mm)
 Application: Potable water and heating systems
 Compatibility: Designed for use with RAUTITAN PX piping and similar 16 mm and 25 mm pipe systems
 Resistance: Chemical and temperature resistance typical of PPSU fittings
How to use
Prepare the pipes by cutting squarely and deburring the ends before assembly. Ensure pipe ends are clean and free of contaminants. Insert the 25 mm and 16 mm pipes into the corresponding ports of the reducing tee following the manufacturer's guidance for connection method (e.g., press-fit, expansion or compatible joining technique). Verify correct insertion depth and secure connections as specified for the chosen RAUTITAN system. After assembly, perform pressure and leak tests in accordance with applicable standards and installation practices.
Usage recommendations
Install the reducing tee only in systems designed for PPSU fittings and observe recommended operating temperature and pressure limits. Store and handle components to avoid contamination of sealing surfaces. For reliable long-term performance, follow RAUTITAN installation instructions and conduct periodic inspections as part of scheduled maintenance.
