## Long description

KAN-therm reduction coupling in polypropylene (PP) model 04108090 is a compact transition fitting designed to connect pipes of different diameters, specifically 90 mm to 50 mm. Manufactured from corrosion-resistant PP material, this coupling provides a stable, low-maintenance joint suitable for plumbing and heating installations where polypropylene components are required. The fitting is intended for use with compatible PP piping systems and offers a streamlined connection without bulky adapters.
Advantages
The polypropylene construction ensures chemical and corrosion resistance and reduces the risk of scale build-up compared with some metallic fittings. The compact design minimizes space requirements and simplifies routing in tight installation areas. The reduction coupling provides consistent dimensional accuracy for reliable connections and is compatible with standard joining methods used for PP pipe systems, contributing to leak-resistant performance when installed correctly.
Suitable for
Connecting a 90 mm pipe to a 50 mm pipe in plumbing systems
Use in residential and commercial heating installations
Applications requiring corrosion-resistant polypropylene fittings
Potable water distribution where PP is specified
Key specifications
Material: Polypropylene (PP)
Connection type: Reduction coupling for differing diameters

How to use
Prepare pipe ends by cutting squarely and removing burrs or debris to ensure full contact with the coupling. Follow the manufacturer’s recommended joining method for polypropylene fittings—this may include solvent welding, thermal fusion, or mechanical connection depending on system design and installer practice. Ensure alignment of the 90 mm and 50 mm pipes and insert fully into the coupling. After joining, verify the joint according to local codes and perform a pressure test at the appropriate test pressure for the installation before placing the system into service.
Usage recommendations
For reliable long-term performance, use this coupling only with compatible PP pipes and approved joining techniques; avoid exposing the fitting to UV or aggressive chemicals not compatible with polypropylene and follow local plumbing and heating standards during installation and testing.
