WEH® Leak Test Quick Connector TW17V for vacuum and pressure testing up to max. 350 bar

The WEH® TW17V 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 pneumatic actuation is very easy and requires only little effort. Simply press the valve button and place the connector loosely into the test piece. On frequent connection and disconnection considerable time and cost savings are achieved thanks to the automation.

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 manual actuation we offer the TW17H with hand lever, for pneumatic applications the TW17P for fully automatic control systems is the right choice.

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