## Summary description

KAN-therm coupling with external thread, size 20x3/4" made of polypropylene (PP), model 04103221. Designed for connecting plastic pipes to threaded fittings or valves, providing a durable joint for water and heating installations. Suitable for use in plumbing and HVAC systems where a 20 mm pipe to 3/4" threaded connection is required.

## Long description

KAN-therm fitting with external thread 20x3/4" PP model 04103221 is a polypropylene coupling designed to join 20 mm plastic pipes to 3/4" threaded fittings or valves. The part provides a stable transition between plastic piping and metal or plastic threaded components used in water supply and heating systems. Its compact form and corrosion-resistant PP construction make it suitable for installations where a simple, reliable threaded connection is required.
Advantages
The polypropylene construction resists corrosion and scaling while remaining lightweight. The external 3/4" thread ensures compatibility with standard threaded valves and fittings used in plumbing and HVAC systems. The coupling creates a leak-resistant junction when installed correctly and offers dimensional stability for typical domestic and light commercial water and heating applications.
Suitable for
 Connecting 20 mm plastic pipes to 3/4" threaded valves and fittings
 Domestic water supply installations
 Heating circuits and radiators requiring a threaded interface
 Repair or retrofit works where plastic-to-threaded transitions are needed
Key specifications
 Material: polypropylene (PP)
 Pipe connection diameter: 20 mm (outer diameter for PP pipe coupling)
 Thread size: external 3/4" (standard pipe thread for fittings and valves)
 Application: cold and hot water, heating systems
 Design: coupling with external threaded end for direct connection to threaded components
How to use
Prepare the pipe end by cutting squarely and deburring to ensure full contact with the fitting. Slide or insert the 20 mm PP pipe into the coupling according to the manufacturer's installation depth guidance, and secure using the recommended joining method for the pipe system (e.g., socket fusion, press, or mechanical insertion depending on the PP system compatibility). Thread the external 3/4" end into the mating fitting or valve using appropriate thread sealant or PTFE tape as required for the system and local codes. Tighten to a suitable torque to avoid over-stressing the polypropylene thread.
Usage recommendations
Use compatible 20 mm PP piping and approved joining techniques for PP systems. Verify thread compatibility and apply suitable sealing material to the external 3/4" thread. Avoid excessive torque to prevent damage to the polypropylene; follow local plumbing standards and the pipe system manufacturer's instructions for pressure and temperature limits.
