Type TW19 is designed for sealing high pressure hydraulic components with internal thread.

The clamping lever-actuated connector safely grips onto the test piece, even in case of high lateral forces, e.g. heavy or rigid hoses. The higher the test pressure the more tightly type TW19 clamps itself in the thread of the test piece. The front O-ring reliably seals off the connection. No additional clamping devices are required.

Having only one seal in the interior of the connector, ease of maintenance is provided.
