    WEH® Connector TW01 | A real multi-talent for leak tests
    Like all WEH® Products the TW01 is extremely durable, easy to maintain and achieves impressive cost savings as a result of excellent productivity gains. Inside bores, irregular or rough hoses and many other components can be instantly connected ready for leak testing, vaccum testing, helium testing and function testing. Automated test procedures allow for significant cost reductions and productivity gains.
Description
WEH® Leak Test Connector TW01 for automated vacuum and pressure testing up to max. 9 bar

The WEH® TW01 Quick Connector is the perfect tool for pressure and vacuum testing as well as for pressure decay, underwater and helium testing. The Connector reliably and quickly seals bores, female tubes and internally threaded components, and can also be used for flushing and filling.

The pneumatic actuation makes the coupling the ideal choice for quality testing during production and automation of test procedures, thus increasing productivity.

Only plug the connector into the test piece, apply pilote pressure and the pressure-tight connection is established - in just seconds without tedious hand-tightening. The easy handling creates significant time and cost saving.

As a standard the WEH® TW01 quick coupler is equipped with a stroke limitation and with an additional front seal for connection to female threads. The elastic front seal compresses into the test piece, compensating for possible tolerances in a component‘s size and reliably seals out of round and rough surfaces. The connector only clamps itself firmly over the sealing rubber of the test piece, but does not have any retaining function. Therefore a fixture must be used.

Special versions, e.g. twin connectors for sealing ports in close proximity to each other are available on request. Shaft extensions or shortenings for TW01 Connectors complement the product family.

Fast test connections for smooth or threaded tubes, bores and female threads - WEH® TW01

WEH offers fastest connectors for components with female thread, bores and smooth tubes with straight tube ends. The pneumatically actuated quick coupling TW01 is the ideal test fitting / tool for low pressure testing, leak testing, vacuum testing and function testing. With the TW01 automated processes and high volume production testing is child's play. The TW01 sealing the inside diameter and provides instant sealing from vacuum up to 9 bar (130 psi).

It provides fast leak tight connections thanks to the WEH® Jaw Locking Mechanism – Just push to connect. The quick release coupling establish a leak free connection into threaded, rough and oily surfaces. With the TW01 components are tested faster than ever before.

The test coupler is used for automated connections in pressure and proof testing, fluid filling, flushing applications, material handling or manufacturing processes and for in-process leak testing of components like cylinders, tanks, valves, regulators, meters, plastic containers, plumbing fixtures, pumps, medical devices, filters, pressure vessels, tube assemblies, etc.
