Your cart is empty.Stop leaks in your car's air conditioning system with this A/C Pro Super Seal AC Stop Leak Kit. This kit has everything you need to fix current leaks and prevent future leaks, so you can protect your car's AC system by yourself. The AC seal kit also helps eliminate moisture that can harm your AC system. A red dye detects leaks that are too large to seal, alerting you to any areas that may require mechanical repair. This kit includes an AC leak sealer that contains 1.5 ounces of R-134a and 1.5 ounces of additives, plus an AC refrigerant hose for dispensing. The AC sealant is compatible with lubricants commonly used in car AC systems, so it won't clog up your AC system when used as directed. Don't forget to follow up on your repair by immediately adding an additional R134a refrigerant to your vehicle’s AC system with an AC recharge hose. (R-134a car refrigerant is sold separately.) Take on car care yourself by recharging your vehicle's AC with A/C Pro. Nothing cools like A/C Pro.
