Fast & Easy Pressure Testing of Tubes
Sealing internal diameters
Wherever straight tubes and bores have to be leak, pressure or vacuum tested, WEH® Connectors are the perfect tool. WEH® Test Connectors reliably seal internal tubes - of both small and large diameter.
A simple clamping lever actuation achieves connection in seconds. This simple operation ensures operators‘ joints are protected from strains resulting from repetitive actions. It also means reduced connection times which achieve a significant increase in productivity and production costs are substantially reduced. Because the WEH® Connector remains securely located in the test piece during testing the need for costly mountings is eliminated. Consistent with WEH‘s high safety standards, operation is safe up to a maximum pressure of 70 bar.
WEH® Test connectors sealing inside the tube
The quick connectors are mainly used in the refrigeration and climate control industry for leak testing of heat exchangers, pressure vessels, valves, compressors, air conditioning and heating systems and many other components. They are also widely used in the automotive industry for testing cooling systems.
The WEH® TW230 Quick Connector is ideally suited for pressure and vacuum testing of straight tubes and bores with an internal diameter of Ø 9.5 mm (3/8“) to 22.2 mm (7/8“) and rated for both vacuum and pressures up to 70 bar max. The use of a radial seal allows the TW230 to compensate for large tube tolerances of up to ± 0.25 mm. Seal adjustment is not necessary within this tolerance range.
The WEH® TW221 Quick Connector is the right choice for low pressure applications up to max. 3 bar. It is available for internal tube diameters of Ø 9.5 mm to 24.4 mm.
WEH also offers connectors for sealing external tube diameters. Innovative WEH solutions consistently offer the right connection to meet your ever changing application needs!
