Type TW17 is designed for sealing internal thread applications. The higher the test pressure the tighter the WEH-Connector clamps itself into the thread of the test piece. The front O-ring reliably seals the connection. No additional clamping devices are required. Time-consuming and expensive testing devices are eliminated.

The connector is available with different actuations:
manually with hand lever, pneumatically with valve head and pneumatically for external manual, semi or fully automatic control systems. Special applications, i.e. connectors in longer or shorter versions, as a plug or with hydraulic actuation etc. are possible.
