WEH® Leak Test Connector TW02 for automated vacuum and pressure testing up to max. 35 bar
The WEH® TW02 Quick Connector is the perfect tool for pressure and vacuum testing as well as for pressure decay, underwater and helium testing. The Connector reliably and quickly seals external tubes and externally threaded components, and can also be used for flushing and filling.
The pneumatic actuation makes the coupling the ideal choice for quality testing during production and automation of test procedures, thus increasing productivity.
Only plug the connector onto the test piece, apply pilote pressure and the pressure-tight connection is established - in just seconds without tedious hand-tightening. The easy handling creates significant time and cost saving.
The elastic front seal compresses onto the test piece, compensating for possible tolerances in a component‘s size and reliably seals out of round and rough surfaces. The connector only clamps itself firmly over the sealing rubber of the test piece, but does not have any retaining function. Therefore a fixture must be used.
Special versions, e.g. twin connectors for sealing ports in close proximity to each other are available on request.
