## Summary description

KAN-therm coupling with internal thread 25x3/4" made of PP (model 04103126) is a pipe fitting designed to join a 25 mm plastic pipe to a 3/4" threaded connection. Suitable for plumbing and heating systems, it provides a durable junction between polypropylene piping and threaded components for water distribution, radiator or boiler connections and general installation use.

## Long description

The KAN-therm coupling with internal thread 25x3/4" PP model 04103126 is a polypropylene pipe fitting designed to connect a 25 mm plastic pipe to a 3/4" female threaded component. Intended for plumbing and heating installations, the coupling provides a transition between polypropylene piping and threaded valves, radiators, boilers or other fixtures. Its simple geometry and corrosion-resistant material make it suitable for potable water systems and closed heating circuits where a durable, leak-resistant threaded junction is required.
Advantages
The coupling is made of polypropylene, which offers chemical resistance and low susceptibility to corrosion compared with metal fittings. Its integrated internal thread ensures a reliable mechanical connection to standard 3/4" male threaded fittings without the need for adapter unions. The compact design reduces installation space and simplifies retrofits or repairs. Because it joins plastic pipe to threaded components directly, it reduces the number of transition parts and potential leak points in a system.
Suitable for
Connecting 25 mm polypropylene pipe to 3/4" threaded valves and fittings
Plumbing systems for cold and hot potable water (where material compatibility is confirmed)
Heating installations such as radiator or boiler connections in closed circuits
Repair, retrofit or extension works where a plastic-to-threaded transition is needed
Key specifications
Material: polypropylene (PP)
Connection 1: 25 mm socket for polypropylene pipe
Connection 2: internal (female) 3/4" thread
Application: plumbing and heating systems
Design: compact coupling for direct pipe-to-thread transition
How to use
Prepare the 25 mm polypropylene pipe by cutting it square and deburring the end. Insert the pipe into the 25 mm socket on the coupling following the manufacturer’s installation method for PP fittings (for example, by using the appropriate joining technique specified for KAN-therm PP components). Thread the male 3/4" fitting into the internal thread and tighten to the recommended torque for the mating component, using suitable sealing material on the male thread if required. After assembly, pressurize and inspect the system for leaks according to applicable installation standards.
Usage recommendations
Verify compatibility of polypropylene with the system media and temperatures before installation. Use correct pipe preparation and approved joining practices for PP fittings. Apply appropriate thread sealant or tape to the male thread as specified by the mating component manufacturer. Follow local plumbing and heating codes and perform pressure testing after installation.
