    WEH provides ideal connections for automation technology. WEH Connectors enable high quantities to be tested for leakage quickly and reliably during production. The TW17 Quick Connector with pneumatic actuation for automated applications and controls connects pressure-tight in seconds to female threads. The TW02 Quick Coupling for automated testing is the ideal tool for connecting to the outer diameter of straight tubes and hoses.
Description
WEH® Leak Test Connector TW02 for automated vacuum and pressure testing up to max. 35 bar

The WEH® TW02 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 male tubes and externally 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 onto 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.

The elastic front seal compresses onto 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.

Fast test connections for smooth tubes with straight tube ends - WEH® TW02

WEH offers fastest connectors for components with smooth tubes with straigh tube ends, bead or collar sealing exterior diameter. The pneumatically actuated quick coupling TW02 is the ideal test fitting / tool for low pressure testing, leak testing, vacuum testing and function testing. With the automated processes and high volume production testing is child's play. The TW02 sealing the external diameter and provides instant sealing from vacuum up to max. 35 bar (510 psi).

It provides fast leak tight connections thanks to the WEH® Jaw Locking Mechanism – Just push to connect. The quick release coupling establish a fast, leak free connection into rough and oily surfaces. With the TW02 components are tested faster than ever before.

The quick release coupling 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, regulatores, meters, plastic containers, plumbing fixtures, pumps, medical devices, filters, pressure vessels, tube assemblies, etc.
