## Summary description

KAN-therm coupling with internal thread 40 x 1 1/4" made of polypropylene (PP), model 04103140. Designed to join a 40 mm plastic pipe to a 1 1/4" threaded metal or plastic fitting. Suitable for plumbing and heating systems that require a durable PP transition coupling. Used for repairs, installations and connecting pipelines in residential and light commercial applications.

## Long description

The KAN-therm coupling with internal thread 40 x 1 1/4" PP (model 04103140) is a polypropylene transition fitting designed to connect a 40 mm plastic pipe to a 1 1/4" threaded fitting. Manufactured from durable PP, this coupling provides a corrosion-resistant interface between plastic pipework and threaded metal or plastic components, suitable for plumbing and heating systems in residential and light commercial installations.
Advantages
This PP coupling offers chemical and corrosion resistance inherent to polypropylene, low weight for easier handling, and thermal stability appropriate for typical domestic plumbing and heating temperatures. The integrated internal thread provides a secure mechanical connection to 1 1/4" threaded fittings while the smooth socket for the 40 mm pipe ensures a reliable joined surface. The design simplifies repairs and retrofits by allowing transition between plastic piping and threaded components without extensive modification.
Suitable for
Connecting 40 mm plastic pipes to 1 1/4" threaded valves, taps, or fittings
Residential plumbing repairs and renovations
Light commercial heating and water distribution systems
Retrofitting existing systems where a thread-to-socket transition is required
Key specifications
Material: polypropylene (PP)
Pipe connection size: 40 mm socket for plastic pipe
Threaded connection: internal 1 1/4" thread (female)
Application: plumbing and heating systems; potable and non-potable water where PP is suitable
Typical properties: corrosion-resistant, lightweight, thermally stable within common system temperature ranges
How to use
Prepare the 40 mm plastic pipe by cutting squarely and removing any burrs or debris. Ensure the mating 1 1/4" threaded fitting is clean and the thread sealant appropriate for the media and material is applied if required. Insert the prepared plastic pipe into the socket end and join according to the pipe system's recommended method for PP (for example, solvent welding or using compatible insertion techniques) or follow the manufacturer's installation guidance. Screw the threaded fitting into the internal 1 1/4" thread and tighten to the torque appropriate for the fitting material and sealant used. Verify alignment and test the assembly for leaks under the system's operating pressure.
Usage recommendations
Select thread sealants compatible with polypropylene and the media handled; avoid excessive torque when tightening to prevent deformation of the PP socket. Confirm temperature and pressure ratings of the overall system to ensure compatibility with PP fittings and follow local plumbing codes during installation.
