Pipe reducer KAN-therm 40x32 mm PP for plastic plumbing connections

KAN-therm PP pipe reducer 40x32 mm is a polypropylene fitting designed to provide a compact and reliable transition between 40 mm and 32 mm plastic pipes in plumbing and heating systems. The reducer ensures continuity of flow and mechanical integrity where pipe diameter changes are required for distribution, fixture connections, or system repairs. Its smooth internal profile minimizes flow disturbance and pressure loss while maintaining compatibility with standard PP piping used in potable water and heating circuits.

Advantages

The polypropylene construction offers chemical resistance, low weight and resistance to corrosion, making the reducer suitable for long-term installation in closed water and heating systems. The fitting delivers consistent dimensional accuracy for simple assembly and stable mechanical connection. Its compact form factor reduces space requirements at transitions and supports straightforward integration into existing PP piping layouts.

Suitable for

• Connecting 40 mm to 32 mm polypropylene pipes in residential and commercial plumbing
• Transition points in heating loops and radiator supply lines
• Repair and maintenance tasks where diameter downsize is required
• Water distribution networks and service risers using PP piping

Key specifications

• Material: polypropylene (PP)
• Connection: socket fitting for PP pipes with matching outer diameters
• Pipe diameters: inlet 40 mm, outlet 32 mm
• Design: concentric reducer with smooth internal bore
• Application: cold and hot water systems, heating circuits (closed systems)
• Operating temperature: suitable for typical domestic heating and potable water temperatures (refer to system design limits)

How to use

Select the reducer when a diameter reduction from 40 mm to 32 mm is required. Prepare pipe ends by cutting squarely and deburring to ensure full insertion depth and avoid stress points. Follow the chosen joining method recommended for KAN-therm PP fittings (e.g., thermal fusion or compatible adhesive system if applicable) and ensure correct alignment during assembly. After installation, pressurize and test the circuit according to local codes and project requirements to confirm leak-tight performance.

Usage recommendations

Store the fitting away from direct sunlight and extreme temperatures prior to installation. Use proper fusion or connection tools compatible with polypropylene systems and observe manufacturer and local regulations for pressure and temperature limits. Inspect connections visually and with pressure testing after installation to ensure reliable operation.
