Field service couplers connect to our special Enviro-Guard hoses to allow access 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
