Interdynamics MRL-3 Super Seal Leak Sealer for R-134A - 3 oz.
The commonly used air conditioning sealer has been on the market since the days of R-12, with little change. However, the introduction of metal component sealers in recent years has revolutionized the industry of air conditioning sealers. While in the air conditioning system, it remains a liquid lubricant and contains additives to penetrate and rejuvenate O-rings, gaskets and other rubber connectors to prevent leakage. Included in Super Seal is a drying agent that gets rid of any moisture that may be inside the air conditioner. If the refrigerant leak occurs in a metal part, the refrigerant leaves the system and chills the outside air causing condensation. This moisture activates the Super Seal fluid to form a scab on the exterior of the metal.
