A/C Leak Sealer

A/C System

Seals small refrigerant leaks in A/C hoses, fittings, and seals by circulating through the system and chemically bonding at leak points.

A/C leak sealer is a specialized additive that circulates through your air conditioning system and chemically seals microscopic leaks in hoses, seals, and connections. It works best on small pinhole leaks and won't repair major damage or punctures. This product is often used as a temporary or preventive measure when an A/C system shows signs of gradual refrigerant loss.
