Reduction coupling KAN-therm PP 110×90 mm model 04108011 for plastic piping

KAN-therm reduction coupling PP 110×90 mm model 04108011 is a polypropylene fitting designed to join plastic pipes with outer diameters of 110 mm and 90 mm. The coupling provides a reliable mechanical connection for fluid transport in plumbing, drainage and heating systems, enabling a smooth transition between different pipe sizes while maintaining flow integrity and resistance to corrosion and common chemicals.

Advantages

The polypropylene construction ensures chemical resistance, low weight and long service life without significant maintenance. The coupling's dimensions are optimized for secure socket connections to standard plastic pipes, providing a tight fit and minimizing the risk of leaks when installed according to recommended procedures. Its simple geometry allows for easy handling and integration into existing plastic piping networks.

Suitable for

• Connecting sewer and drainage pipes of 110 mm to 90 mm diameter
• Adapting plastic piping runs in residential and commercial plumbing systems
• Transitions in heating distribution systems that use compatible plastic pipe materials
• Retrofit and repair tasks where a reduction in pipe diameter is required

Key specifications

• Material: polypropylene (PP)
• Connection types: socket/joint for outer diameters 110 mm and 90 mm
• Primary application: plastic piping systems for plumbing, drainage and heating
• Resistance: corrosion and many common chemicals suitable for typical installation environments
• Physical properties: lightweight and dimensionally stable for standard installation methods

How to use

Prepare both pipe ends by cutting square and deburring to ensure full insertion into the coupling sockets. Clean mating surfaces from dirt, grease and moisture. Insert the larger and smaller pipes into the respective ends of the coupling until they reach the internal stop. Secure the connection following the pipe manufacturer's and local installation standards; this may include solvent welding, thermal fusion, mechanical seals or clamp systems depending on the pipe material and joint design. Verify alignment and test the assembly under appropriate pressure or flow conditions before final commissioning.

Usage recommendations

Use compatible pipe materials and approved joining methods for polypropylene fittings. Avoid exposure to prolonged direct sunlight without UV protection and follow temperature and pressure limits of the overall piping system. For critical applications, perform pressure tests and consult local codes to confirm suitability for the intended fluid and operating conditions.
