Reducer KAN-therm PP 32×25 mm 04108033 for plastic pipe connections

KAN-therm PP reducer 32×25 mm is a polypropylene pipe fitting engineered to connect pipes of different diameters and provide a secure transition from 32 mm to 25 mm. Designed for plastic plumbing and heating systems, this reducer enables reliable diameter reduction for water supply and central heating installations. The fitting is compatible with polypropylene pipes and designed to ensure a tight joint when installed according to applicable standards and installation practices.

Advantages

The reducer is made of polypropylene (PP), offering chemical resistance and long-term dimensional stability in commonly used water and heating applications. Its compact design enables space-efficient installations in confined areas. The smooth internal bore reduces flow resistance and minimizes turbulence at the transition point. Manufactured to consistent quality tolerances, the fitting supports repeatable, leak-free joints when assembled with appropriate methods for PP systems.

Suitable for

• Domestic and commercial water supply systems using polypropylene pipes
• Central heating installations where a reduction from 32 mm to 25 mm is required
• Plastic plumbing repairs and retrofit projects involving diameter changes
• Pipe routing in limited spaces where compact fittings are needed

Key specifications

• Material: polypropylene (PP)
• Connection type: socket-fitting for PP pipe systems
• Nominal diameters: 32 mm to 25 mm reduction
• Application media: potable water and heating fluids compatible with PP
• Operating temperature range: suitable for typical domestic hot water and central heating temperatures (follow system design limits)

How to use

Prepare the pipe ends by cutting them square and removing burrs or debris. Ensure pipes and fitting sockets are clean and dry before assembly. Fit the 32 mm pipe into the larger socket and the 25 mm pipe into the smaller socket, following the recommended joining method for polypropylene systems (for example, fusion welding or the specified mechanical connection). After assembly, allow any welded joints to cool and stabilize before pressurizing the system. Verify joint integrity with appropriate pressure testing procedures in accordance with local regulations and installation standards.

Usage recommendations

Use the reducer only with compatible PP piping and approved joining methods. Observe maximum temperature and pressure limits of the overall piping system, and follow manufacturer installation guidelines for heat fusion or mechanical connections. During installation, avoid excessive bending or axial loads at the joint to maintain long-term leak-free performance.
