Coupling (mufa) KAN-therm 40 mm PP model 04103040

The KAN-therm 40 mm PP coupling (mufa) is a polypropylene connector designed for joining 40 mm plastic pipes in plumbing and heating installations. Made from corrosion-resistant polypropylene, this coupling creates a stable and watertight connection suitable for water distribution, heating circuits and sanitary systems in residential and light commercial buildings. The simple cylindrical design supports inline pipe extension or repair while maintaining flow characteristics of the pipe run.

Advantages

This PP coupling offers chemical and corrosion resistance, low weight and compatibility with common 40 mm plastic pipe systems. Its uniform polymer construction reduces the risk of galvanic or electrolytic corrosion and provides long-term dimensional stability. The product is easy to handle and install, enabling quick maintenance or extension of plastic piping without specialized metal fittings.

Suitable for

• Joining 40 mm polypropylene or other compatible plastic pipes in potable water systems
• Repairing or extending heating circuit piping in radiators and underfloor heating
• Sanitary installations such as waste and drainage connections when compatible with material
• Light commercial and residential plumbing projects requiring corrosion-resistant joints

Key specifications

• Material: polypropylene (PP)
• Connection size: 40 mm nominal diameter
• Type: straight coupling (inline connector)
• Application: water distribution, heating circuits, sanitary installations
• Suitability: for plastic pipe systems compatible with PP couplings

How to use

Prepare pipe ends by cutting square and removing burrs, ensuring the inner surfaces are clean and dry. Slide the coupling onto one pipe end and align the second pipe to achieve full insertion depth according to the pipe system's installation guidelines. Depending on the specific piping system, secure the joint by the required method (e.g., solvent welding, thermal fusion, or mechanical fastening) as recommended for PP fittings and the connecting pipe type. After installation, inspect the joint for proper alignment and perform a pressure or leak test following local codes and system requirements.

Usage recommendations

Use this coupling only with pipe materials and joining methods recommended for polypropylene fittings. Verify compatibility of adhesives or fusion equipment before use. Perform pressure testing after installation and protect the coupling from prolonged UV exposure when used in external or unprotected locations.
