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 Stop Leak may stop the yearly recharge of lost refrigerant.
