    Modular WEH® Connector for manual, semi or fully automatic pressure and function tests. The WEH® TW17 Quick Connector simplifies manufacturing processes, improves efficiency and increases productivity assuring safe, reliable and leak tight connections. Within seconds components with internal thread can easily be function and pressure tested from vacuum up to max. 350 bar. Made of high-grade corrosion resistant stainless steel, the WEH® TW17 fits internal threads from 1/8” to 2”.
  • WEH® TW17 | Product Benefits
    WEH® TW17 | Product Benefits
    The WEH® TW17 is ideally suited for pneumatic and hydraulic pressure tests and functions tests on internally threaded components, i.e. engines, cylinders, pressure vessels, hoses, fittings, etc. The higher the test pressure, the tighter the WEH® Connector will clamp itself into the thread of the test piece and provides a pressure-tight connection in seconds.

    WEH® TW17 | Actuation Possibilities
    Designed for sealing standardized internal thread applications, the TW17 Quick Coupling is available with different actuations: Manually with hand lever, pneumatically with valve head and pneumatically for external manual, semi or fully automatic control systems. Special versions, e.g. connectors in longer or shorter versions, as a plug or with hydraulic actuation etc. are possible.
Description
WEH® Connector TW17H for testing of components with internal thread, lever actuation, vacuum up to max. 350 bar - Product family

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 internal 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.
