WEH® Leak Test Quick Connector TW17H for vacuum and pressure testing up to max. 350 bar

The WEH® TW17H connector is the perfect tool for pressure, function and vacuum testing during production and rated for pressure up to max. 350 bar. The safe and pressure-tight connection to standardised female threads is established in just seconds – without tedious hand tightening.

No additional thread sealants are required, time-consuming and expensive clamping and testing devices are eliminated. The manual actuation via hand lever is very easy. Only actuate the hand lever and place the TW17H loosely into the test piece. On frequent connection and disconnection considerable time and cost savings are achieved.

Bores have been added as standard to the clamping jaws for body sizes 5 – 6 of the connector for increased media flow and enhanced productivity.

The quick connector is available for low pressure up to 50 bar and high pressure up to 350 bar. For automated applications with pneumatic actuation we offer the TW17V with valve button and the TW17P for fully automatic control systems.

Special versions such as e.g. longer or shorter versions, plug versions or versions for hydraulic actuation etc. are also possible.
