Reduction Coupling KAN-therm 75x50 mm PP (model 04108075)

KAN-therm reduction coupling in polypropylene (PP) with dimensions 75x50 mm is a reducing sleeve designed to connect pipes of different diameters in plumbing and heating systems. The coupling provides a reliable transition from a 75 mm pipe to a 50 mm pipe and is intended for use where a durable PP connector is required for system connections and diameter changes.

Advantages

The PP construction offers chemical resistance and long-term dimensional stability in non-corrosive environments. Its one-piece design ensures consistent alignment of mating pipes and reduces the risk of leaks when installed correctly. The coupling is lightweight, easy to handle, and compatible with common PP joining methods used in heating and plumbing installations.

Suitable for

• Transitioning between 75 mm and 50 mm polypropylene pipes
• Plumbing systems in residential and commercial buildings
• Heating circulation networks where diameter reduction is required
• Repair or modification of existing PP piping systems

Key specifications

• Material: polypropylene (PP)
• Connection type: reducing coupling / sleeve
• Outer diameter transition: from 75 mm to 50 mm
• Typical application temperature: suitable for standard plumbing and heating operating ranges (refer to system design for exact limits)
• Mechanical form: single-piece reducing sleeve for butt/joint fusion or compatible joining method

How to use

Prepare pipe ends by cutting square and removing burrs or debris. Ensure mating pipe surfaces are clean and dry before joining. Install the reduction coupling following the approved joining method for polypropylene components used in the system (for example, butt fusion, socket fusion, or the manufacturer-recommended technique). Maintain correct alignment and follow cooling or curing times specified for the chosen joining process. Verify the joint integrity after installation and conduct pressure testing according to local codes and system requirements.

Usage recommendations

Use the coupling within the recommended temperature and pressure ranges for polypropylene systems and apply appropriate installation tools and procedures. For applications with higher temperatures or aggressive media, consult system specifications to confirm material suitability. Follow local standards and manufacturer guidance for fusion or mechanical joining to ensure leak-free, durable connections.
