    The quick release couplers with their distinctive blue and red colour coding for the low and high pressure side of AC systems are the ideal tool for filling / charging of refrigerants (R134a). They connect instantly to the Schrader SAE 1/4" service port and are available as straight or 90° elbow couplings. When disconnecting hazardous discharge of refrigerant is reduced by 99 %. No twist, no turn, no hand-tightening. Just push to connect.

    The WEH® TW111 filling connector is very easy to use. Only pull back the sliding sleeve of the quick coupling and place the connector onto the Schrader valve thread. When pushing the sliding sleeve forward, the clamping jaws are locked and the internal stop valve opens. Refrigerant filling can now begin.
Description
WEH® Connector TW111 for filling refrigerants on Schrader valves 1/4" SAE , red (high pressure), chloroprene seal, max. 42 bar, 90° media inlet UNF 7/16"-20 external thread

Thanks to the easy push & pull actuation, the TW111 connects to Schrader port UNF 7/16“ –20 external thread (equivalent to 1/4" – SAE tube connection) in just seconds. The safe and pressure-tight connection is established without continuous screwing and unscrewing of threaded ports. Thus the operator's joints are protected from injuries arising from repetitive motion. Work flows are considerably facilitated and a high operating comfort is achieved.

In addition, the WEH® TW111 filling connector reduces the loss of refrigerant by up to 99%. An integrated shut-off valve allows only a minimum of refrigerant to escape into the air. Besides environmental protection, the operator is protected from cold burns to the hands.

The small outer diameter of only 25 mm simplifies the connection procedure to test pieces in restricted areas. Thus not only connection times are reduced, but also costs are cut and the productivity is increased.

The service connector is rated for an operating pressure of max. 42 bar and has a 90° media inlet, a chloroprene front seal and a colour coded red sliding sleeve for the high pressure connection port of the customer.

The Connector is also available with inline media inlet and blue sliding sleeve for the low pressure connection port.
