Being open at one side the WEH® Quick Connector is easy to connect, especially to cylinder valves with large hand wheel and lateral gauge.
Simply place the connector body of the WEH® Quick Connector WEH® TW42 over the cylinder valve, align it with the index pins and move upwards. The pressure-tight connection is made.
The pressure-assisted piston prevents accidental disconnection under pressure and provides additional safety.
The TW42 is also available for non-residual pressure valves.
This WEH® Quick Connector is available for gas cylinder valves acc. to CGA 870, others on request.
Connectors for oxygen applications are oxygen cleaned and free of oil and grease.
