WEH® TW17 Modular Quick Connector
for leak and function testing up to max. 5,000 psi (350 bar)

Take advantage of its unique functionality


Thanks to its modular design with three different actuations, this connector can be used in a variety of functions. The actuations can be replaced quickly at any time. All you need to do is screw off the rear of the connector and replace it with the required actuation.

The following types of actuations are available:

Manual actuation via lever
Pneumatic actuation via valve head
Pneumatic actuation for external manual, semi or fully automatic control systems


The higher the test pressure, the more firmly the WEH® Connector clamps into the thread of the test piece. This ensures a pressure-tight connection and improves safety for the operator.


Pressure-tight and secure connections are achieved in seconds – with no need for time-consuming hand-tightening. Bores have been added as standard to the clamping jaws for body sizes 5 - 8 of the connector for increased media flow and enhanced productivity. This modification is also possible for body sizes 1 - 4.


The front seal of the TW17 Quick coupler can be replaced quickly and easily – with no need for disassembly or long downtimes. This makes the connector particularly maintenance-friendly and reduces maintenance downtime
to a minimum.


Manufactured of high quality materials and Made in Germany, the Quick Connector is very durable and robust, making it ideal for industrial use.


Each WEH® TW17 Connector is subject to strict quality controls and intensive pressure and durability tests in our own testing laboratory. In addition to that, all quick connectors conform to the European Pressure Equipment Directive 2014/68/EU. Quality control is ensured in accordance with ISO 9001.


If the connector is used as a plug, the media inlet can be closed. For this purpose, we provide a brass screw plug for use at the lower pressure range of up to 725 psi (50 bar) and a steel unit for the high pressure range up to 5,000 psi (350 bar).

Special applications


The WEH® TW17H connector is the perfect tool for pneumatic and hydraulic pressure & function testing of components with internal thread, such as engines, cylinders, pressure vessels, hoses, fittings etc.
