Reducer coupling KAN-therm PP 63×50 mm 04108065 for polypropylene piping

KAN-therm PP reducer coupling 63×50 mm is a polypropylene fitting designed to connect pipes of different diameters in plastic piping systems. The fitting provides a smooth internal transition from 63 mm to 50 mm, maintaining flow characteristics while enabling a secure, leak-resistant joint when installed with compatible fusion or socket-welding methods. It is intended for use in heating, potable water and general plumbing systems that use KAN-therm PP piping.

Advantages

The reducer coupling is made of polypropylene, offering chemical resistance, low thermal conductivity and corrosion-free service life. Its concentric design ensures even flow with minimal turbulence at the diameter change. The fitting is compatible with standard heat-fusion and socket-welding installation techniques used for polypropylene systems, providing durable joints and reliable sealing suitable for potable water and heating applications.

Suitable for

• Connecting 63 mm PP pipe to 50 mm PP pipe in distribution lines
• Domestic and commercial heating systems
• Potable water supply and plumbing networks
• Retrofit work where diameter reduction is required

Key specifications

• Material: polypropylene (PP)
• Connection type: fusion/socket-welding compatible
• Nominal diameters: 63 mm to 50 mm
• Design: concentric reducer for smooth internal transition
• Application temperature range: suitable for standard hot and cold water and heating system temperatures (per PP system limits)

How to use

Prepare pipe ends by cutting square and cleaning them from debris and burrs. Ensure both pipes match the nominal diameters (63 mm and 50 mm) and verify material compatibility with KAN-therm PP fittings. Install the reducer coupling using the recommended fusion or socket-welding procedure for polypropylene: align the pipes concentrically, apply the correct welding temperature and time as specified by the welding equipment manufacturer, allow the joint to cool undisturbed, and then verify the integrity of the connection. Follow local codes and the piping system manufacturer’s installation guidelines.

Usage recommendations

Use appropriate welding tools and follow equipment temperature and timing settings for polypropylene; avoid mechanical stress on newly joined sections until the joint has fully cooled. Inspect completed joints for alignment and leaks before system commissioning, and follow applicable norms for potable water and heating installations.
