Transform your vehicle's AC performance with this comprehensive 4-piece Enviro-Safe R1234YF Auto AC Recharge Kit. The kit includes two cans of Arctic Air for maximum cooling performance and moisture removal, one can of Oil Charge to replenish lost oil, and one can of Stop Leak to help recondition rubber o-rings and seals. The included gauge enables precise system monitoring. Arctic Air works to reduce friction and deliver colder air temperatures, while the Oil Charge blend is specifically formulated for 1234YF systems using mineral, ester, or PAG oils. The Stop Leak component helps address common seal-related issues that develop over time. This professional-grade kit installs like standard refrigerant and is compatible with automotive refrigerants (except ammonia and CO2 systems). Note: Cannot be added to fully charged systems or shipped to Alaska/Hawaii. Professional installation recommended for optimal results.
