Compression threaded coupling Perfexim 16 mm x 1/2" (model 62-732-1615-000)

Perfexim compression threaded coupling 16 mm x 1/2" is a mechanical connector designed to join 16 mm plastic or metal plumbing pipes to a fitting with a 1/2" male thread. The coupling provides a sealed transition between a press-fit pipe line and a threaded outlet, suitable for potable water and central heating installations. It is intended for use by professional installers and DIY users who need a reliable pipe-to-thread connection without soldering or adhesive.

Advantages

The coupling offers a compact design that enables quick installation and a secure compressive seal around the pipe. Its threaded outlet provides standard 1/2" connection compatibility with valves, radiators or other fittings. The product reduces the need for additional sealing compounds when installed correctly and is suitable for systems operating within typical residential water and heating pressure and temperature ranges.

Suitable for

• Connecting 16 mm supply pipes to 1/2" threaded valves and fittings
• Transitions between press-fit pipework and threaded radiator or appliance inlets
• Domestic potable water distribution and central heating circuits
• On-site repair or retrofit work where a mechanical, non-soldered joint is preferred

Key specifications

• Pipe outside diameter compatibility: 16 mm
• Thread connection: female 1/2" (compatible with standard 1/2" male threads)
• Type: compression (mechanical compressive seal)
• Intended media: potable water and heating fluids
• Typical installation environment: residential and light commercial plumbing and heating

How to use

Prepare the pipe by cutting it squarely and deburring the outer edge. Slide the compression nut and ferrule (if supplied) onto the pipe, insert the pipe fully into the coupling body so it seats against the internal stop, then hand-tighten the compression nut onto the threaded body. Complete the connection by tightening the nut with a wrench to the torque recommended by the installer’s practice or manufacturer instructions until the compressive seal is formed; avoid over-tightening. Screw the 1/2" male fitting into the coupling’s thread, using appropriate thread sealant if required for the application or where additional leak protection is desired.

Usage recommendations

Confirm material compatibility with the pipe and system fluid, ensure pipe OD is 16 mm, and follow local plumbing codes. Pressure-test the completed connection according to installation standards before finalizing insulation or covering. For heated systems, allow for thermal expansion and use appropriate supports and joint protection where needed.
