The WEH® type TK350 quick release coupling is used for quick changes of connectors, either for repair or for a changeover to another type of connector. For example a change from residual pressure to non residual pressure connectors is easily achieved. No additional swivel joint is necessary with the TK350-TN350. The TK350 is also equipped with a red indicator ring which is not visible when correctly connected and a bayonet lock for additonal safety against accidental disconnection.
When changing over to gas cylinders with different cylinder valves, the filling hose has to be disconnected from the filling connector. The new WEH® quick release coupling has solved this problem, as each WEH® connector can use the TK350 quick coupling and the corresponding TN350 nipple fitted to the filling hose. This system ensures a quick and easy changeover of filling connectors.
