    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.
Connectool 111 for refrigerant charging on Schrader service valves - Series

Thanks to the easy push & pull actuation, the TW111 service coupler connects instantly to ¼” / 5/16" SAE male Schrader valves, thus being the ideal tool for filling refrigerants.

The integrated shut-off valve prevents the media escape by up to 99%. The refrigerant remains in the filling hose and can be correctly disposed of. Besides environmental protection, the operator is thus protected from cold burns to the hands.

The service connector is rated for an operating pressure of max. 610 psi and has a chloroprene seal as standard for most common refrigerants. For filling R410A refrigerant the quick coupler has an EPDM front seal. It is the customer’s responsibility to clarify the media compatibility.

The TW111 is available with either straight or 90° media inlet. The colour-coded sliding sleeve, red or blue, for the high or low side service port of A/C units avoids mistaken use.

Service quick coupling for filling refrigerants with Schrader valves - WEH® TW111

The service quick coupler TW111 is the ideal service port access fitting for charging and recharging refrigerants and air conditioning plants with Schrader valves. The service coupler connects instantly to your male threaded service port of RAC systems / ACR systems. The TW111 offers quick connect and quick disconnect thanks to the WEH® Jaw Locking Mechanism and the easy to operate sliding sleeve. The service quick coupler also eliminates hazardous discharge of refrigerant from high-side / low-side of system when disconnecting. Applications are recharging of home air conditioners and refrigerators.

The HVAC-R Connector is equipped with a UNF 7/16“-20 thread (equivalent to ¼“ – SAE tube connection) or with an UNF1/2“-20 (equivalent to 5/16“ – SAE tube connection) and is either available for high pressure (red sliding sleeve) or for low pressure (blue sliding sleeve).

With the WEH® Service Connector refrigerant filling (for example R134A, R407A, R407B, R410A, R507, etc.) is made easy. It is the ideal tool for filling / recharging in the refrigerating and air conditioning industry.
