WEH® Connector TW751 function and pressure testing of pressure gauges with male thread - Product family

How to save time and money

The WEH® TW751 Quick connector has been developed for function- and pressure testing of externally threaded manometers up to a max. pressure (PN) of 1000 bar. Tedious hand tightening is no longer needed and intricate testing devices are a thing of the past. In comparison to threaded connections there are significant time and cost reductions due to the efficient handling of WEH® Connectors. It is also ideal for automated test procedures.

The connector is characterised by its robust design and ease of operation. The connection procedure is quite simple:
Activate the pilot pressure, so that the sealing disc retracts. Afterwards pull back the grip sleeve - the clamping jaws spread apart and the test piece can be inserted. Push the grip sleeve completely forward - the clamping jaws lock the test piece. Relieve the pilot pressure - the sealing disc moves forward and reliably seals the connection. Testing can now proceed.

The WEH® TW751 quick coupling is equipped with a NBR front seal. Other sealing materials on request. It is the customer‘s responsibility to clarify the media compatibility.
