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).
