WEH® Connector TW03 for testing of components with female thread, manual actuation, vacuum up to max. 345 bar - Product family

Connects to
Please select variant!

The WEH® Quick Connector TW03 is the perfect tool for pressure and vacuum testing of components with female thread up to 345 bar max.

Only place the connector into the threaded port and hand-tighten it until the o-ring seal contacts the test piece - the pressure-tight connection is established. The WEH® TW03 seals without wrenches, sealants or tape saving connection time & costs.

The higher the test pressure, the tighter the WEH® Connector will clamp itself into the threaded 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.
