WEH® Leak Test Quick Connector TW17P for vacuum and pressure testing up to max. 350 bar

The WEH® TW17P connector is the perfect tool for automated 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 for external manual, semi or fully automatic control systems is effected via an external valve. 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 TW17V with valve button 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.
