Closed cooling systems have to be function tested and leak tested as well as filled regularly. The WEH® TW141 Quick Connector is the suitable solution for this application.
The TW141 can be connected to straight tubes within seconds – without hand tightening. The hand lever just needs to be actuated and the connector can be pushed directly onto the tube. After the hand lever is released again, the TW141 is connected pressure-tight and the test medium can be supplied or evacuated. For disconnection, the hand lever just needs to be actuated again and the connector can be removed.
The key benefit is the fact that no lateral forces, which might cause tube bendings, are generated when connecting. Thanks to the internal pressure support, disconnection is only possible below a pressure of 5 bar. WEH® TW141 is an indispensable tool for the automation of test procedures, e.g. during the production of tubes.
Tubes with an external diameter of 3.5 mm to 22.0 mm can be filled easily. Even function tests, vacuum tests, leak tests and pressure tests from vacuum up to 100 bar do not cause any problems at these tubes. For difficult accessibly tubes like heat exchangers, WEH® offers the TW141L, an extended version of WEH® TW141. A large variety of adaptors for the various media inlets as well as a retaining plate for additional security are available.
