Revitalize your high-mileage vehicle's air conditioning with the A/C Pro® High Mileage Ultra Synthetic R-134a Refrigerant Auto A/C Recharge Refill. Specially formulated for vehicles with 75,000 miles or more, this A/C refrigerant contains anti-wear additives that help extend the life of older and/or high-usage air conditioning systems by eliminating acid and moisture buildup. It goes beyond recharging your system to seal and detect leaks, preventing refrigerant loss and maintaining optimal system functionality. The integrated A/C leak sealer effectively seals common leaks in rubber components such as hoses, O-rings, and gaskets, while the A/C leak detector with UV dye glows to detect any leaks that were too large to be sealed (UV light required). Use this automotive A/C recharge refill with your existing A/C Pro® hose and gauge to replenish your refrigerant levels in roughly 10 minutes. Keep your high-mileage vehicle's climate control system operating at its best with the A/C Pro® High Mileage Ultra Synthetic R-134a Refrigerant Auto A/C Recharge Refill.
