## Summary description

Reducing coupler KAN-therm in polypropylene (PP) for joining plastic pipes of different diameters. This model 04108091 connects 90 mm to 63 mm pipes and is designed for reliable, leak-resistant transitions in plumbing and heating systems. Suitable for use with compatible PP piping systems in residential and commercial installations.

## Long description

The KAN-therm reducing coupler in polypropylene (PP) provides a durable connection between plastic pipes of different diameters. This 90×63 mm model is engineered for secure, leak-resistant transitions in plumbing and heating systems where a change in pipe size is required. Manufactured for compatibility with KAN-therm and other PP piping systems, the coupler offers stable mechanical strength and chemical resistance typical of polypropylene fittings.
Advantages
The reducing coupler is made from polypropylene material that resists chemical corrosion and maintains structural integrity at normal operating temperatures. Its socket design ensures uniform seating of pipes and an even joint surface for fusion or mechanical joining methods. The component delivers reliable flow transition with minimal turbulence and reduced risk of leakage when installed according to system requirements.
Suitable for
Residential hot and cold water distribution systems
Commercial plumbing and heating installations
Connections between different-diameter PP pipeline sections
Retrofit or expansion projects that require downsizing a pipeline
Key specifications
Material: polypropylene (PP)
Connection sizes: 90 mm to 63 mm
Type: reducing coupler for plastic pipe systems
Application: plumbing and heating pipelines
Design: socket-style coupling for fusion or compatible mechanical joining
How to use
Prepare pipe ends by cutting squarely and removing burrs, ensuring correct diameter and clean surfaces. Follow the chosen joining method compatible with PP fittings—such as butt or socket fusion, or approved mechanical joining—observing manufacturer temperature, pressure and welding parameters where applicable. Insert pipes fully into the coupler sockets to the required depth and allow joints to cool or set as specified before subjecting the line to pressure tests. Verify alignment and support the pipeline to avoid stress on the joint.
Usage recommendations
Use this reducing coupler in systems designed for polypropylene components and follow system manufacturer instructions for jointing, pressure testing and operating temperature limits. Do not expose the fitting to incompatible chemicals or temperatures beyond the PP material ratings. For long-term reliability, ensure proper pipe support, avoid point loads on the joint and verify compatibility with seals or adhesives before use.
