(ROB-18191A) High-Side Manual Coupler, Red Acutator

• Field service couplers connect to our special Enviro-Guard hoses to allow acess to service ports on automotive R-134a A/C systems • The quick connect design has an integral safety sleeve which protects against injury and refrigerant loss if the coupler is disconnected under pressure • The compact design easily fits into tight quarters, which is especially handy for retrofits. Six-ball couplers provide a more stable grip on the fitting than do couplers with four balls
