The WEH® Gas Filling Connector TW52 has been developed especially for filling gas cylinders with gaseous and liquid CO₂ or refrigerants.
Connection to the cylinder is made within seconds without tedious screwing and unscrewing, thus preventing RSI resulting in the inflammation of tendons and abrasion of joints.
The quick coupling is also suitable for filling one litre cylinders, e.g. for soda drinks and optionally available with the TVCO₂ linear valve.
The TW52 is suited for non-residual pressure valves and rated for a pressure range of max. 250 bar.
On request, the quick coupling is also available for residual pressure valves and as version for non-residual pressure valves incl. linear valve TVCO2 (operating pressure PS max. 150 bar)
Other gas connection ports, i.e. DIN, BS, NF, CGA etc. are available on request.

High pressure fill coupling for CO2 / refrigerants - WEH® TW52
The manually actuated quick coupling TW52 is the ideal fitting for high pressure CO2 filling of gas cylinders up to max. 200 bar. The quick coupler connects instantly to your non-residual gas cylinder valve with external thread. They offer quick connect and quick disconnect thanks to the WEH® Jaw Locking Mechanism and the easy to operate grip sleeve. Just push to connect. The TW52 quick release coupling is available for a large variety of national standards (DIN, CGA, BS, NF).
