## Long description

Varioterm connector adapter GW3/4" x 16x2 PEX black is a press-fit plumbing fitting designed to join a 3/4" female threaded component to 16x2 mm PEX tubing. Manufactured for use in potable water and heating systems, this compact adapter offers a mechanical transition that allows installation of valves, taps or appliances with standard 3/4" female threads onto PEX networks. The black finish identifies the part and supports visual matching with other system components.
Advantages
The press-fit connection design delivers quick installation without the need for soldering or adhesive, reducing assembly time and on-site tools. The adapter provides a secure mechanical joint that is suitable for hot and cold water circuits and heating systems when installed according to applicable regulations. Its compact form factor helps save space in confined installation areas and simplifies routing between threaded fittings and PEX piping.

Key specifications

 Material: corrosion-resistant construction suitable for plumbing use
 Color/finish: black
 Application temperature: suitable for cold and hot water and heating systems when installed per guidelines

How to use
Prepare the PEX tubing by cutting square and deburring the end, then verify the tubing outer diameter is 16 mm with a wall thickness of 2 mm. Ensure the threaded component has a compatible 3/4" female thread and is clean and undamaged. Insert the PEX pipe into the press-fit side of the adapter to the correct depth and use the recommended pressing tool or crimping method specified for the system to form the mechanical joint. Thread the 3/4" fitting onto the female thread, using appropriate sealing method on the thread if required by the installation practice or local codes. After assembly, inspect joints and test the system for leaks following standard commissioning procedures.
Usage recommendations
Use appropriate press tools and rings certified for 16x2 PEX to ensure correct joint formation. Follow local plumbing and heating regulations for potable water and heating system installations, and perform pressure testing after installation. Avoid exposing the adapter to aggressive chemicals or mechanical loads beyond normal service conditions.
