Wall connection for radiator 20 PP-R Detal-met PG20

Wall connection for radiator 20 PP-R Detal-met PG20 is a polypropylene (PP-R) pipe adapter intended for connecting radiators to 20 mm heating or hot-water supply pipelines. Manufactured by Detal-met, this fitting provides a corrosion-resistant interface between the radiator inlet/outlet and PP-R piping systems used in residential and commercial installations. The product is designed to integrate with standard 20 mm polypropylene piping and offers a compact form factor for near-wall radiator connections.

Advantages

The polypropylene construction ensures long-term resistance to corrosion and scaling, suitable for hot-water systems. The compact design simplifies installation in tight spaces close to the wall and reduces the need for additional fittings. Compatibility with 20 mm PP-R piping provides a reliable mechanical and hydraulic connection that maintains flow integrity and minimizes leakage risk when installed correctly.

Suitable for

• Connecting radiators to 20 mm PP-R heating and hot-water supply pipes
• Residential central heating systems and apartment installations
• Commercial buildings where polypropylene piping is used
• Retrofit and new-build radiator installations requiring a corrosion-resistant connection

Key specifications

• Material: polypropylene (PP-R)
• Intended pipe diameter: 20 mm
• Application: radiator inlet/outlet connection to PP-R piping
• Suitable medium: hot water for heating and domestic hot-water systems
• Installation position: wall-mounted radiator connection

How to use

Prepare the 20 mm PP-R pipe end by cutting square and deburring to ensure a clean joint. Join the wall connection to the PP-R pipe using the recommended thermal fusion or solvent-welding method compatible with the pipe and fitting material, following manufacturer instructions for heating time and cooling. Position the fitting so the radiator valve or tailpiece aligns correctly with the radiator inlet/outlet, then secure the radiator to the mounting brackets. After assembly, pressurize the system and inspect joints for leaks before putting the heating system into service.

Usage recommendations

Use appropriate tools and follow local plumbing codes. Verify compatibility with radiator valves and mounting hardware. Perform pressure testing according to system requirements and allow proper cooling time after thermal fusion to ensure joint integrity.
