Connects to
Please select variant!

The WEH® Quick Connector TW04 is the perfect tool for pressure and vacuum testing of components with male thread up to 50 bar max, as well as for filling and venting.

Only place the connector onto the threaded port and hand-tighten it until the o-ring seal contacts the test piece - the pressure-tight connection is established. The WEH® TW04 seals without wrenches, sealants or tape saving connection time & costs.

The higher the test pressure, the tighter the WEH® Connector will clamp itself onto the test piece port. The pressure-assisted piston ensures a pressure-tight connection.

Wear-resistant NBR seals meet most industrial requirements and are very durable. The connector is extremely easy to maintain with simple seal replacement and minimizes down-time.

The WEH® TW04 Screw connector is equipped with a swivel joint as standard enabling the connector to be turned into the most convenient position and eliminates any twisting of the media line. This provides the operator with easy and convenient handling.
