WEH® TW152 with straight media inlet | FunctionThe TW152 is designed to connect directly to the standard thread of the cylinder valve for medical oxygen filling. Only pull back the sliding sleeve and place the filling connector onto the male thread of the cylinder valve. Then push the sleeve forward - the clamping jaws lock securely onto the cylinder valve thread and the pressure-tight connection is established. Pressure can be applied and filling proceed.
The function is quite simple: pull back the sliding sleeve and place the filling connector onto the external thread of the cylinder valve. The split collet design system locks securely onto the cylinder valve thread and seals tightly.
The connector has an internal locking mechanism preventing disconnection under pressure. The TW152 can be connected to cylinder valves with non-residual pressure valves and valves with integrated pressure regulators. Due to its compact design, it is also suitable for use in confined spaces. The filling connector is also available with 90° media inlet and for residual pressure valves.
This WEH® 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.
