Compression fitting KAN-therm 20 mm x 3/4" for PP pipes (1209271002)

KAN-therm compression fitting 20 mm x 3/4" for PP pipes is a mechanical connector designed to join polypropylene piping to a 3/4" threaded outlet. The fitting creates a secure seal between the smooth PP pipe and a threaded component without requiring heat fusion tools. It is intended for use in plumbing and heating systems where a compact, serviceable transition from PP pipe to a threaded connection is required.

Advantages

The compression design enables a leak-resistant mechanical seal that can be assembled with common hand tools. Compatible with standard 20 mm polypropylene pipes, the fitting provides a durable connection that resists corrosion and chemical degradation typical of plastic-to-metal transitions. Its compact profile simplifies installation in confined spaces and allows for straightforward replacement or maintenance without cutting or welding the pipe network.

Suitable for

• Residential potable water distribution with 20 mm PP piping
• Heating circuits in small-scale or light commercial installations
• Connecting PP pipe runs to valves, manifolds or threaded appliances (3/4")
• Repair sections where a threaded outlet is required

Key specifications

• Pipe compatibility: polypropylene (PP) pipes with 20 mm outer diameter
• Threaded connection: 3/4" male/female (as specified in product title)
• Connection type: compression fitting with mechanical sealing ring
• Typical applications: potable water and heating systems
• Material characteristics: corrosion-resistant plastic and metal contact surfaces suitable for mixed-material connections

How to use

Cut the PP pipe end square and deburr to ensure a smooth insertion surface. Slide the compression nut and sealing components onto the pipe, insert the pipe fully into the fitting until it seats against the internal stop, then tighten the compression nut to the recommended hand or tool torque to compress the seal. Connect the 3/4" threaded outlet and verify the alignment. After assembly, perform a pressure test according to local regulations to confirm leak-tightness before putting the circuit into service.

Usage recommendations

Use only with compatible 20 mm PP pipe and ensure all mating threads are clean and undamaged. Avoid overtightening the compression nut; follow torque guidance from system designers or local codes. For systems carrying potable water or under continuous pressure, conduct periodic visual inspections and pressure tests after installation and after thermal cycling.
