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 connector is also suitable for filling one litre cylinders, e.g. for soda drinks.
The TW52 quick coupling is suited for non-residual pressure valves and rated for a pressure range of max. 250 bar.
On request, the connector 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)
The gas fitting is suited for gas cylinder valves acc. to DIN 477 and is available on request also for other connection possibilities, i.e. BS, NF, CGA etc.
