    WEH® TW141L | Function
    The WEH® Quick release coupling TW141L is very easy to use. Only place the quick disconnect onto the test piece and release the hand lever. The pressure-tight connection is established and the test media can be supplied. Now pressure testing / function testing of heat exchangers or other difficult-to-access test pieces can be effected.
Description
WEH® Connector TW141L for testing straight tubes, filling of closed cooling circuits, lever actuation, vacuum up to max. 1,450 psi

The WEH® TW141L Quick Connector is ideally suited for function, pressure and leak testing of straight tubes and for filling closed cooling circuits with refrigerants.

The Connector has been developed especially for difficult-to-access test pieces. The extended body allows connection to closely spaced tubes.

The higher the test pressure, the tighter the WEH® Connector will clamp itself onto the threaded test piece port thus establishing a leak-tight connection in just seconds. An internal pressure support provides additional operator safety by ensuring that disconnection is not possible until pressure has decreased to a safe value below 5 bar.

The front O-ring reliably seals the connection and can be easily replaced during maintenance.

Thanks to the jaw locking mechanism, surface pressure and thus deformation of the test piece is reduced. Additional sealants are not required. Complex and expensive clamping and testing devices are eliminated.

The TW141 is a lever-actuated connector which creates no lateral forces that can distort the test piece or filling port when connecting and disconnecting. The easy and comfortable actuation of the connector makes for reduced testing times and facilitated workflows.
