Angle Fitting REHAU Kolano PX 16×90° RAUTITAN PPSU

REHAU Kolano PX 16×90° RAUTITAN PPSU is a 90° angle fitting designed for RAUTITAN piping systems. Manufactured from PPSU thermoplastic, this compact elbow connects 16 mm pipes and provides a reliable change of direction in potable water and heating installations. The fitting is intended for systems where high temperature resistance and long-term chemical stability are required, combining dimensional accuracy with corrosion-free operation.

Advantages

The PPSU construction offers elevated temperature and hydrolysis resistance compared with standard plastics, enabling stable performance in hot water and heating circuits. Its compact 90° design reduces space requirements at pipe turns and simplifies routing in confined installations. The fitting ensures leak-tight connections when used with compatible RAUTITAN installation methods, and its smooth internal surface supports efficient flow with minimal pressure loss.

Suitable for

• Domestic potable water distribution with 16 mm RAUTITAN pipes
• Underfloor heating and radiator circuits in residential or light commercial buildings
• Areas requiring corrosion-free and chemically stable fittings
• Installations where compact elbow components are needed to save space

Key specifications

• Material: PPSU (polyphenylsulfone) thermoplastic
• Angle: 90° elbow
• Connection size: for 16 mm RAUTITAN pipes
• Application: potable water and heating circuits
• Design: compact elbow for space-saving pipe routing

How to use

Install the Kolano PX into RAUTITAN piping systems following the manufacturer’s installation method for 16 mm components. Prepare pipe ends according to recommended cutting and deburring procedures, insert the pipe fully into the fitting, and complete the connection using the appropriate RAUTITAN joining technique. Ensure alignment and support of adjacent pipe runs to prevent mechanical stress on the elbow. Verify system integrity with a pressure test after installation in accordance with local standards and RAUTITAN guidelines.

Usage recommendations

Use this PPSU elbow in systems designed for RAUTITAN components and specify compatible 16 mm pipes and fittings. Avoid exposing the fitting to aggressive chemicals outside normal potable water and heating media, and follow recommended temperature and pressure limits provided by RAUTITAN. Regularly inspect critical joints after commissioning and before placing systems into continuous service.
