The WEH® TW42 filling connector has been specially developed for filling of gas cylinders using a pin-index system with medical oxygen. It is designed for a nominal pressure of 200 bar and available for residual and non-residual pressure valves. For gas cylinders with residual pressure valve, the CGA 870 connector is also fitted with an RPV pin to open the residual pressure valve.
Made of corrosion resistant stainless steel and brass, the filling connector is extremely robust and durable. Its weight of only 700 g makes it very easy to handle.
With its bracket housing, which opens from the side, the quick connector is easy to connect to its cylinder valve. Simply place the connector around the cylinder valve so that the coding pin is positioned opposite the bore holes on the cylinder valve and actuate the clamping lever. The pressure-tight connection has now been established, with no need for laborious screwing and unscrewing. This also allows connection to the cylinder valve using a large handwheel with a manometer positioned at its side.
The pressure-assisted piston ensures a secure connection, as it is not possible to remove the filling connector while it is under pressure. This ensures the highest possible level of safety for the operator.
Save time and increase your productivity by using this unique pin-index connector. It is available for gas cylinder valves conforming to CGA 870, and for other valves upon request. All connectors are oxygen cleaned, and are free of oils and greases (oxygen tested).
