## Long description

Uponor compression coupling S-Press Heimeier 16–G1/2M is a radiator connection fitting designed for 16 mm pipe systems and G1/2 male radiator valve threads. The coupling combines a press-type S-Press joint for connection to plastic or composite pipes with a threaded male end that mates to standard radiator valves. It is intended for central heating and radiator installations where a permanent, hydraulically secure connection is required and is compatible with Uponor press-installation tools and common S-Press installation practices.
Advantages
The S-Press design provides a reliable press-fit connection that reduces the risk of leaks compared with traditional compression-only fittings. Integration with a G1/2 male thread allows straightforward attachment to radiator valves, simplifying installation and minimizing additional adapters. The coupling is suitable for use in both residential and commercial heating systems and supports efficient installation workflows when used with standard press tools.
Suitable for
 Connecting 16 mm plastic or composite heating pipes to radiator valves with G1/2 threads
 Permanent radiator connections in central heating systems
 Retrofit and new-build radiator installations in apartments and houses
 Commercial heating installations where press-fit connections are specified
Key specifications
 Connection to pipe: 16 mm press-fit S-Press
 Threaded end: male G1/2 for radiator valves
 Intended application: radiator connection for central heating systems
 Compatibility: designed for use with Uponor press-installation tools and S-Press compatible pipes
 Material characteristics: metal press body with threaded male end suitable for typical heating media
How to use
Prepare the 16 mm pipe by cutting it square and deburring the cut end. Slide the pipe fully into the S-Press socket until it seats against the internal stop. Use the appropriate Uponor-compatible press tool and jaw for the S-Press system to perform the press operation at the designated pressing area, creating a permanent hydraulic seal. Once the pipe side is pressed, screw the male G1/2 end onto the radiator valve and tighten to the required torque stated by the radiator valve manufacturer. Pressure-test the installation according to local regulations and system requirements.
Usage recommendations
Use only press tools and jaws approved for S-Press fittings and follow manufacturer instructions for pressing, tightening torques, and pressure testing. Ensure pipe compatibility (material and wall thickness) with S-Press fittings and check sealing surfaces on radiator valves before assembly.
