    WEH® TW241 | Function

    The WEH® TW241 quick connect / 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 external straight tube diameters , clamping lever actuation, vacuum up to max. 70 bar

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 44.0 mm. Further typical applications are underwater, pressure decay and helium tests.

The connector is available in 7 body sizes. From an external tube Ø of 24.0 mm, the connector provides extremely high flow rates ensuring a further increase in productivity.

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 smooth tubes - WEH® TW241

The clamping lever actuated quick coupling TW241 improve in-process leak testing, high pressure testing, run testing and function testing of smooth tubes with straight tube ends sealing the exterior / outside diameter. They offer the fastest way to connect and disconnect thanks to the WEH® Jaw Locking Mechanism and the easy to operate clamping lever. The sealing design seals reliably and provides a instant connection from vacuum up to max. 70 bar (1,015 psi).

Just push to connect - no need for hand-tightening, no tapes, no thread sealants. The TW241 quick release coupling is ideal for external connections to copper, steel and aluminum tubes and mainly used for testing automotive and refrigeration air conditioning components / HVAC-R systems for example heat exchangers, pressure vessels, gauges and valves - they are tested faster than ever before.
