Perfexim screw coupling 702, 16 mm to G 1/2" female thread

Perfexim screw coupling 702 is a mechanical adapter for joining 16 mm pipes or hoses to components with a G 1/2" female thread. Designed for plumbing and heating installations, the coupling creates a stable, threaded transition from a 16 mm line to a standard G 1/2" fitting. The product is intended for use where a compact, secure metal-to-thread connection is required, such as connecting radiators, domestic water lines, and small hydraulic circuits.

Advantages

The coupling offers a straightforward threaded connection that ensures a reliable seal when installed correctly. Its compact design allows installation in confined spaces and at transitions between 16 mm tubing and common G 1/2" threaded fixtures. The product reduces the need for additional adapters by providing a direct interface between pipe or hose and G 1/2" female-threaded components and is compatible with typical plumbing and heating materials when used with appropriate sealing methods.

Suitable for

• Connecting 16 mm copper, PEX or flexible hoses to G 1/2" female-threaded fittings
• Domestic water supply lines and bathroom fixture connections
• Radiator inlet and outlet connections in central heating systems
• Small hydraulic or low-pressure piping runs requiring a threaded transition

Key specifications

• Connection A: designed for 16 mm pipe or hose
• Connection B: G 1/2" female thread
• Function: mechanical screw coupling for transition between tubing and threaded fittings
• Typical application pressure: suitable for domestic plumbing and low-pressure heating systems (verify system limits before use)
• Material considerations: compatible with common plumbing materials when assembled with appropriate seals
• Compact form factor suitable for installations with limited space

How to use

Prepare the 16 mm pipe or hose end by cutting square and deburring. Insert the tube fully into the 16 mm side of the coupling and tighten the threaded G 1/2" connection to the mating female fitting using an appropriate wrench. Use thread sealant tape or an approved sealant on the G 1/2" male thread where required by the installation standards. After assembly, pressurize the system and inspect the joint for leaks; retighten or reseal as necessary following manufacturer and local plumbing guidelines.

Usage recommendations

Verify material compatibility and maximum allowable pressure and temperature of the overall system before installation. Use correct sealing methods for G 1/2" threads and follow local plumbing codes. For persistent leaks or uncertain installations, consult a qualified plumber.
