The WEH® TW49 filling connector has been specially developed for filling of gas cylinders using a pin-index system and is suitable for pin-index cylinder valves without hand wheels and manometers.

Operating is quite simple:
Just place the quick connector onto the valve, actuate the clamping lever and the pressure-tight connection is established. The connection is made in seconds and without the need for laborious screwing.

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.

The TW49 is very easy to handle. It can be switched from right-handed to left-handed operation, and also allows you to re-configure the clamping lever to the operator’s individual preferences.

Save time and increase your productivity by using this unique pin-index connector. This quick connector is available for gas cylinder valves conforming to CGA 870, and for other valves upon request. Connectors for oxygen applications are oxygen cleaned, and are free of oils and greases.
