Highside Service Coupler 1234yf. Field service couplers connect to our special Enviro-Guard hoses to allow access to service ports on automotive R-1234yf 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.
