The Robinair 18191A is a Red High Side Manual Coupler for Automotive R-134a Systems. The field service coupler connects to 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 coupler provides a more stable grip on the fitting than do coupler with four balls.
