Includes: 1 Can Stop leak for 1234YF 1 Gauge For 1234YF automotive use With age, o rings and seals will shrink and deteriorate. When Enviro-Safe Stop Leak is added to your a/c system, it reconditions the rubber o rings and seals. When the Stop Leak product is installed in an air conditioning system, the product mixes with the refrigerant and oil. As the product circulates in the system, it comes in contact with the o rings and seals causing them to swell, resulting in "no leak". Stop leak will not repair or "fix" cuts or worn out o rings or seals. 1 can will treat 1 vehicle. Installing Enviro-Safe Stop Leak may stop the yearly recharge of lost refrigerant. The top of the can has a R134a top. Use only with Mineral, Ester, and Pag oils.
