Providing access to R-134a service ports in cramped engine bays, these high and low side manual couplers connect to Enviro-Guard hoses for automotive A/C maintenance. The compact design fits into tight quarters during retrofits and utilizes a six-ball locking mechanism for a more stable grip on fittings than four-ball alternatives. To prevent injury and refrigerant loss, an integral safety sleeve protects the user if the quick-connect is disconnected while under pressure.
