    WEH® TW241 | Function
    The 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.
Description
WEH® Connector TW241 for straight tubes, tube OD 15.9 mm (5/8"), clamping lever actuation, vacuum up to max. 1,015 psi

The WEH® TW241 is the ideal tool for quick and easy leak testing at straight copper, steel or aluminium tubes with an male Ø of 15.9 mm (5/8"). 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 75 psi.

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.
