    WEH® TW18 | Product Benefits
    The WEH® TW18 is ideally suited for pneumatic and hydraulic pressure tests and functions tests on externally threaded components, i.e. engines, cylinders, pressure vessels, hoses, fittings, etc. The higher the test pressure, the tighter the WEH® Connector will clamp itself onto the thread of the test piece and provides a pressure-tight connection in seconds.

    WEH® TW18 | Actuation Possibilities
    The WEH® TW18 Quick Connector is designed for sealing standardized male thread applications. The TW18 quick connector is available with different actuations. The actuation can be easily changed at any time by simply unscrewing the rear part of the connector and replacing it with the chosen actuation. The following actuations are available: Manually with hand lever, pneumatically with valve head and pneumatically for male manual, semi or fully automatic control systems. Therefore, the TW18 is ideally suited for use in automated systems for high-volume testing during production. Special versions, e.g. connectors in longer or shorter versions, as a plug or with hydraulic actuation etc. are possible.
Description
WEH® Leak Test Quick Connector TW18V for vacuum and pressure testing up to max. 350 bar

The WEH® TW18V connector is the perfect tool for automated pressure, function and vacuum testing during production and rated for pressures up to max. 5,000 psi. The safe and pressure-tight connection to standardised male 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 automated processes.

The higher the test pressure, the tighter the WEH® Connector will clamp itself onto the test piece port thus providing added safety for operators.

The quick connector is available for low pressure up to 725 psi and high pressure up to 5,000 psi. For manual actuation the TW18H with hand lever is available and for pneumatic applications the TW18P for fully automatic control systems is the right choice.

Fast test connections for externally threaded components - WEH® TW18

WEH offers fastest connectors for components with male thread. The pneumatically actuated quick coupling TW18 is the ideal test fitting / tool for pneumatic or hydraulic pressure testing, leak testing and function testing. It provides safe and fast leak tight connections thanks to the WEH® Jaw Locking Mechanism - Just push to connect. The TW18 quick release coupling is mainly used for in-process leak testing automotive and hydraulic components during production but also for vacuum testing and high pressure testing of components like engines / engine blocks, fuel systems, gauges, transmitters, tanks, pressure vessels, cylinders, steering racks / steering systems, aggregates, hose fittings, etc.

Whether tube connection (DIN3902), threaded stem (DIN7631 / DIN7647), Whitworth tube threads (DIN ISO 228-1), NPT or SAE J512 (45° cone), SAE J513, SAE J514 JIC 37°, the WEH® TW18 Quick coupler for pneumatic and hydraulic leak tests connects to virtually all standardised types of male threads.

The higher the test pressure, the tighter the WEH® Connector will clamp itself into the threaded test piece port thus establishing a leak tight connection in just seconds - without hand tightening. The instant leak tight and high pressure connection eliminates tape, sealant and wrenches. Front O-ring reliably seals the connection and can be easily replaced during maintenance.
