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.
Description
WEH® Connector TW241 for straight tubes, tube OD 22.2 mm (7/8"), clamping lever actuation, vacuum up to max. 70 bar
The WEH® TW241 Quick connector enables quick and easy leak testing of smooth tubes with straight tube ends of copper, steel or aluminium with an outer diameter of 22.2 mm (7/8"). The connector is suitable for underwater, pressure decay and helium testing.WEH® TW241 seals exterior diameters of straight tubes within seconds and bridges large 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 tube, actuate the clamping lever and the pressure tight connection is made. An internal pressure support provides additional safety for the operator 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.
