KAN-therm PPSU Ultraline reducing tee 14 mm, threadless plumbing fitting

KAN-therm PPSU Ultraline reducing tee 14 mm is a plumbing fitting made from polyphenylsulfone (PPSU) designed to create a reliable three-way junction in piping systems. Intended for use with 14 mm lines, this reducing tee joins pipes with minimal thermal expansion and high resistance to corrosion and hot water aging. The component is suitable for potable water and heating installations where PPSU components are specified and where a compact, durable tee is required.

Advantages

The PPSU construction offers elevated chemical and temperature resistance compared with standard polymer fittings, ensuring long-term dimensional stability and resistance to hydrolysis. Its reducing tee geometry provides a compact connection point for branch lines while maintaining flow performance for small-diameter systems. The material’s resistance to hot water and repeated thermal cycles reduces the risk of leaks and degradation over extended service life.

Suitable for

• Domestic potable water distribution in small-diameter installations
• Underfloor heating and radiator branch connections using 14 mm lines
• Compact service manifolds and appliance feed lines
• Systems requiring corrosion-resistant plastic fittings in contact with hot water

Key specifications

• Material: Polyphenylsulfone (PPSU)
• Nominal branch size: 14 mm
• Configuration: Reducing tee for three-way connection
• Temperature resistance suitable for hot water applications
• Corrosion and hydrolysis resistant polymer construction

How to use

Install the reducing tee into the piping layout at the intended branch point following the installation method recommended for PPSU components in your system (press-fit, fusion or compatible joining technique). Ensure pipe ends are cut square, deburred and cleaned before insertion to achieve a secure joint. Verify alignment and supporting clamps to prevent mechanical stress on the fitting and connected pipes. After assembly, perform pressure and leak tests according to local plumbing standards before putting the system into regular operation.

Usage recommendations

Use this PPSU reducing tee in systems designed for plastic fittings rated for hot potable water; avoid exposure to aggressive chemicals or fluids outside the intended use. Follow manufacturer guidelines for compatible joining methods and comply with applicable local and national plumbing codes when installing and testing the fitting.
