WEH® Connector TW241
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.
