Improving cylinder filling efficiency with WEH® CGA Gas ConnectorsJust push WEH gas connector onto / into your CGA gas cylinder thread. No wrench tightening or thread sealants needed. WEH gas connectors are the best choice for improving cylinder filling efficiency by reducing operating times. The types TW54 and TW57 connect directly to CGA 580 / CGA 540 cylinder valve thread. A large variety of actuation loops and levers is available. WEH offers a complete product range for a large variety of gases and gas mixures, e.g. inert gases, oxygen, nitrogen, propane, acetylene, CO2, medical gases etc. WEH® Connection solutions for gaseous applications connect directly to the cylinder valve thread and provide a pressure-tight connection in seconds. WEH® Filling Connectors are available for valve configurations having internal or external threads (with or without a residual pressure valve) or PIN-Index connections. Improve your productivity using the unique WEH® Connector for gas filling applications.

WEH® Accessories | Improved efficiency for gas fillingVarious adapter models are required to fill gas cylinders with differing cylinder valves. The TK350-TN350 quick release system by WEH® ensures quick and easy WEH adapter changes. The bayonet lock releases the first adapter immediately and connects to the next adapter just as quickly. You save time and money. The 360° TD1 swivel joint is a perfect choice for moving a depressurised WEH® adapter into the perfect connection position. The swivel joint also prevents the filling hose from twisting.
The highly innovative WEH® jaw locking mechanism establishes a secure and pressure-tight connection in seconds.The expandable thread segments clamp together firmly on the thread of the cylinder valve, pressure sealing the valve at the same time.
Simply place the CGA 540 connector onto the gas cylinder and close the loop around it. The pressure-tight connection has now been established – with no need for laborious screwing and unscrewing. This simple, time-saving one-handed operation simplifies the connecting procedure and makes fuelling times shorter.
For increased safety for the operator, the connector is fitted with an integrated safety peg. The gas pressure activates the safety peg automatically, preventing the valve from being disconnected accidentally while under pressure.
The gas cylinder connection is also ideal for pallet-filling too, ensuring increased efficiency and further increases in productivity.
The quick connector is available for gas cylinder valves conforming to DIN, BS, NF, CGA, etc.
Connectors for oxygen applications are oxygen cleaned, and are free of oils and greases.
