The WEH® TW01 Quick Connector reliably and quickly seals inside bores, irregular or rough holes and internally threaded components. Fitted with elastomer seals ideal for sealing out of round and rough surfaces and clearing large tolerances on the test piece. 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.As a standard the WEH® TW01 is equipped with a stroke limitation and for connection to internal threads with an additional plane sealing.Because of the pneumatic actuation, the connector is particularly well suited for automation of test procedures.Special versions, e.g. twin connectors for sealing ports in close proximity to each other are available on request. Shaft extensions or shortenings for TW01 connectors are also available.
