KAN-therm PPSU push-fitting insert 14x2 for plumbing connections

The KAN-therm PPSU push-fitting insert 14x2 is a precision-molded component intended for use inside push-type plumbing fittings. Made from polyphenylsulfone (PPSU), the insert is engineered to provide a corrosion-resistant, dimensionally stable sealing surface between plastic or composite pipes and push fittings. Designed for potable water and central heating systems, this compact insert supports a secure mechanical connection and contributes to long-term joint reliability in residential and commercial installations.

Advantages

The PPSU material offers high temperature and chemical resistance while maintaining dimensional stability, which reduces the risk of deformation under thermal cycling. Its push-fit geometry facilitates quick installation without the need for soldering or adhesive, and the compact 14x2 size is compatible with a wide range of push-type fittings used in plumbing and heating applications. The insert’s corrosion resistance and suitability for potable water systems make it a practical choice where hygiene and durability are required.

Suitable for

• Potable water distribution systems
• Central heating loop connections
• Renovation and retrofit plumbing where push-fit joints are preferred
• Compact installations with limited access requiring quick fittings

Key specifications

• Material: Polyphenylsulfone (PPSU)
• Nominal pipe size compatibility: 14 mm outer diameter, 2 mm wall thickness
• Type: Push-fitting insert for push-type plumbing fittings
• Use cases: Cold and hot potable water, central heating systems
• Temperature resistance: Suitable for typical domestic hot water and heating temperatures (material rated for elevated temperatures)
• Corrosion resistance: High resistance to chemical and corrosive effects in water systems
• Form factor: Compact insert designed for fast installation within push fittings

How to use

Ensure the pipe end is cut square, deburred and free of dirt or damage before insertion. Insert the KAN-therm PPSU push-fitting insert into the push-type fitting seating area, then fully push the prepared pipe into the fitting until it reaches the stop. Verify that the pipe is engaged securely by gentle pull-back. Follow any system-specific assembly guidelines and pressure/temperature limits provided by the fitting manufacturer and applicable installation standards.

Usage recommendations

Use with compatible push-type fittings and pipes that match the 14x2 size. Inspect joints after installation and pressure-test the system according to local regulations. Avoid using damaged or deformed pipes; replace inserts if any visible defects are found prior to assembly.
