## Summary description

KAN-therm Mufa PP Ø90 mm is a polypropylene coupling designed to join Ø90 mm pipes in polypropylene piping systems. The fitting provides a butt-joint connection for plumbing, heating or industrial fluid transport applications. It is intended for use with compatible PP pipes and welding or fusion installation methods, offering a simple mechanical solution for extending or repairing lines.

## Long description

The KAN-therm PP coupling (mufa) Ø90 mm is a polypropylene pipe fitting designed to create a butt-joint connection between Ø90 mm polypropylene pipes. Intended for use in plumbing, heating and industrial fluid transport systems, the coupling enables straightforward extension or repair of PP pipe runs when installed with appropriate welding or fusion techniques. The product is compatible with standard PP pipe dimensions and provides a corrosion-resistant, chemically inert joint suitable for many water, heating and non-aggressive fluid applications.
Advantages
The coupling is made of polypropylene, which ensures good chemical resistance and long-term dimensional stability. Its simple geometry supports reliable fusion or welding connections that produce leak-resistant joints when installed according to recommended procedures. The fitting is lightweight and resistant to corrosion, reducing maintenance needs. It is suitable for use in systems where a hygienic, non-metallic connection is preferred and where thermal expansion characteristics of PP are acceptable.
Suitable for
 Joining Ø90 mm polypropylene pipes in plumbing systems
 Repairing damaged sections of PP pipe runs
 Extending pipeline lengths in heating installations
 Industrial fluid transport where polypropylene is chemically compatible
Key specifications
 Material: polypropylene (PP)
 Connection type: butt-joint fusion/welding
 Nominal pipe diameter: 90 mm (outer diameter profile compatible with Ø90 mm PP pipes)
 Application: plumbing, heating, industrial fluid systems
 Properties: corrosion-resistant, chemically inert, lightweight
How to use
Prepare the pipe ends by cutting square and removing burrs and contaminants. Ensure pipe surfaces and the coupling are clean, dry and free from grease. Align the pipes concentrically in the coupling sleeve and perform butt fusion or welding in accordance with the welding equipment manufacturer’s instructions and applicable installation standards. Allow the joint to cool under recommended conditions before applying pressure or returning the system to service. Follow local codes and safety practices during installation.
Usage recommendations
Use appropriate fusion equipment and trained personnel for butt-welding polypropylene components. Confirm chemical compatibility of transported fluids with polypropylene and account for thermal expansion in long runs. Inspect completed joints for uniform fusion bead and absence of gaps prior to commissioning.
