WEH® Connector TW19 for testing of components with female thread, clamping lever actuation, vacuum up to max. 350 bar - Product family

Connects to
Please select variant!

The WEH® TW19 Quick Connector with clamping lever actuation provides high clamping force. It is ideal for applications with high lateral forces or varying pressure impulses caused by heavy or rigid hoses.

The higher the test pressure, the tighter the WEH® Connector clamps itself into the thread of the test piece thus establishing a pressure-tight connection in just seconds. The front O-ring reliably seals the connection and can be easily replaced at each maintenance. Having only one seal in the interior of the connector, ease of maintenance is provided.

Additional sealants and sealing tapes are not required. Time-consuming and expensive clamping and testing devices are eliminated.

The WEH® TW19 Quick Connector is the ideal tool for internally threaded applications (metric ISO threads, Whitworth tube threads, NPT threads etc.). Available for high pressure and low pressure.
