KAN-therm coupling with internal thread 75x2 1/2" PP – model 04103175

The KAN-therm coupling with internal thread 75x2 1/2" PP (model 04103175) is a polypropylene pipe fitting engineered to join a 75 mm outer diameter plastic pipe with a 2 mm wall thickness to a standard 1/2" female threaded component. Designed for plumbing and heating systems, this coupling enables a reliable transition between PP piping and threaded metal or plastic fittings, valves or appliances. It is suitable for repair, installation and replacement work in both residential and commercial installations where a threaded connection is required.

Advantages

The coupling is made of polypropylene, providing corrosion resistance and compatibility with common plumbing media used in heating and water installations. Its design ensures a secure mechanical connection to the pipe and a standard internal thread for straightforward assembly with threaded components. The product delivers a compact and lightweight solution that reduces the need for complex adapters while maintaining chemical and thermal stability appropriate for typical domestic and light-commercial systems.

Suitable for

• Connecting 75 mm OD PP pipes (2 mm wall) to 1/2" threaded valves or fittings
• Repairing or replacing sections in residential heating and plumbing systems
• Transitions between plastic distribution pipes and threaded appliances or meters
• Installation work where a compact threaded interface is required

Key specifications

• Material: polypropylene (PP)
• Pipe connection size: 75 mm outer diameter, 2 mm wall thickness
• Thread type: internal (female) 1/2"
• Application: plumbing and heating systems for potable water and heating circuits
• Construction: single-piece coupling providing transition from pipe to thread

How to use

Prepare the PP pipe end by cutting it square and deburring to ensure a clean, smooth surface. Slide the coupling onto the pipe according to the manufacturer's recommended joining method for PP fittings (for example, suitable adhesive or fusion technique where applicable) and secure the threaded side to the mating 1/2" male thread using appropriate thread sealant or tape if required by the installation practice. Ensure alignment is correct and tighten to the torque recommended for the connected threaded component to avoid overstressing the plastic body.

Usage recommendations

Verify compatibility of the coupling with system media and operating temperatures. Use appropriate joining methods for PP materials and follow local plumbing standards. When connecting to metal fittings, use suitable thread sealing and avoid excessive torque to prevent damage to the polypropylene thread.
