WEH® Connector TW57
The WEH® TW57 Quick connector for gas cylinder valves with male thread provides a pressure-tight connection in seconds. The split collet design system locks securely onto the cylinder valve thread and seals tightly.
Safety features
A fully developed design with simple actuation controlling the functioning of the gas connector.
The quick connector cannot be disconnected under pressure because a special safety peg protrudes and locks the connector against removal.
The TW57 for oxygen has venting bores (see opposite picture) in the front sleeve for lateral venting of gas in case of accidental gas leakage, thus preventing pressure built-up in the connector.
The TW57 is suitable for gas cylinders with a nominal operating pressure of 200 bar resp. 300 bar.
This quick connector is available for gas cylinder valves acc. to DIN, BS, NF, CGA etc.
Connectors for oxygen applications are oxygen cleaned and free of oil and grease.
