    The WEH® TW54 filling connector creates a pressure-tight connection on gas cylinders in seconds – without any need for time-consuming screw connections. The connector comes equipped with an integrated safety peg to comply with highest safety standards. It ejects under pressure and effectively prevents any disconnection under pressure. The quick coupling also features a red mark on the front, which indicates a correct adaptor connection.
Description
WEH® Connector TW54 for filling gas cylinders with internal thread - Series
The WEH® TW54 filling connector is the ideal tool for filling gas cylinders with internal thread. It is designed for a nominal pressure of 200 or 300 bar and available for residual and non-residual pressure valves. There is a huge choice of actuation systems for the different valves and protection caps, including loop, lever or wire rope.

The highly innovative WEH® jaw locking mechanism establishes a secure and pressure-tight connection in seconds. The split collet design system close tight onto the thread of the cylinder valve while sealing the valve pressure-tight at the same time.

Simply place the CGA 580 connector into the gas cylinder valve and close the loop around it. The pressure-tight connection has now been established – with no need for laborious screwing and unscrewing. This simple, time-saving one-handed operation simplifies the connecting procedure and makes fuelling times shorter.

For increased safety for the operator, the connector is fitted with an integrated safety peg. The gas pressure activates the safety peg automatically, preventing the valve from being disconnected accidentally while under pressure.

The gas cylinder connection is also ideal for pallet-filling too, ensuring increased efficiency and further increases in productivity.

The quick connector is available for gas cylinder valves conforming to DIN, BS, NF, CGA, etc.
Connectors for oxygen applications are oxygen cleaned, and are free of oils and greases.
