WEH® TW241 | FunctionThe WEH® TW241 quick disconnect is very easy to operate. Only push the quick coupling onto the test piece until it stops and turn the lever through 90° to seal the test piece. Then test pressure can be applied and pressure testing up to 70 bar can proceed.
The WEH® TW241 is the ideal tool for quick and easy leak testing at straight copper, steel or aluminium tubes with an external Ø of 6.0 mm to 22.2 mm. Further typical applications are underwater, pressure decay and helium tests.
The WEH® TW241 seals exterior tube diameters within seconds and bridges tube tolerances of up to ± 0.25 mm (required roundness of external tube diameter max. 0.25 mm) with no operational adjustment of seals.
The WEH® Jaw locking mechanism provides maximum grip with minimum distortion of the test piece. There is no need for additional fixing.
Operation is amazingly easy. Plug the WEH® Connector onto the test piece and actuate the clamping lever downwards or upwards to establish the pressure-tight connection. An internal pressure support provides for additional operator safety ensuring that disconnection is not possible until pressure has decreased to a safe value below 5 bar.
The WEH® TW241 is equipped with a chloroprene front seal. Other sealing materials on request. It is the customer‘s responsibility to clarify the media compatibility.

Fast test connections for straight tubes - WEH® TW241
The clamping lever actuated quick coupling TW241 for high pressure testing, leak testing and function testing of straight tubes sealing the exterior diameter. They offer the fastest way to connect and disconnect thanks to the WEH® Jaw Locking Mechanism and the easy to operate clamping lever. Just push to connect - no need for hand-tightening, no tapes, no thread sealants. The TW241 quick release coupling is mainly used for testing automotive and refrigeration air conditioning components - they are tested faster than ever before.
