## Summary description

KAN-therm compression reducer fitting in PPSU material, ULTRALINE series, size 20/16. Designed for connecting pipes of different diameters in plumbing and heating systems, providing a secure, leak-resistant transition between 20 mm and 16 mm pipes. Suitable for potable water, central heating circuits and underfloor heating; used where durable, corrosion-resistant plastic fittings are required.

## Long description

The KAN-therm compression reducer fitting PPSU ULTRALINE 20/16 is a plastic transition fitting designed for plumbing and heating installations. Made from PPSU material and belonging to the ULTRALINE series, this reducer creates a secure, leak-resistant connection between a 20 mm pipe and a 16 mm pipe. It is intended for use in potable water systems, central heating circuits and underfloor heating where chemical and thermal resistance, plus long-term dimensional stability, are required.
Advantages
The PPSU construction offers high mechanical strength, good resistance to hot water and many common chemicals, and a low tendency to creep under load. The compression design allows installation without hot-work or special tools beyond a proper pipe cutter and compression tool, ensuring consistent sealing and quick assembly. Corrosion-free plastic eliminates galvanic and electrochemical degradation risks common with metallic fittings, and the compact reducer profile saves space in manifold and confined installations.
Suitable for
Potable (drinking) water distribution systems
Central heating circuits and radiator connections
Underfloor heating manifolds and risers
Retrofit and new-build residential plumbing
Key specifications
Material: PPSU (polyphenylsulfone) for the body and compression components
Connection type: compression reducer for 20 mm to 16 mm pipe transition
Series: ULTRALINE, designed for plumbing and heating applications
Suitable media: potable water and heating fluids within recommended temperature ranges
Corrosion resistance: inherent plastic resistance to rust and electrochemical corrosion
Operating suitability: compatible with central heating and underfloor heating systems
How to use
Prepare the pipes by cutting squarely and removing any burrs. Slide the compression ring and nut onto each pipe end as required, insert the pipe fully into the fitting body until it reaches the stop, and tighten the compression nut to the manufacturer’s recommended torque using an appropriate compression tool or wrench. Verify alignment and ensure the connection is seated correctly. After assembly, pressure-test the system following local codes and installation standards before putting the installation into regular operation.
Usage recommendations
Use the fitting within the manufacturer’s specified temperature and pressure limits, avoid excessive mechanical strain at the joint, and always follow applicable plumbing and heating regulations. For potable water lines, flush and check for leaks after installation. If used in heating systems, observe compatibility with system antifreeze or additives and perform routine inspections.
