    The 8 Best AC Leak Sealers & Stoppers<\/h2>\n

    1. Leak Saver Direct Leak Sealer – Best Overall<\/h3>\n

    Check Latest Price<\/span><\/a><\/div>\n

    The Leak Saver<\/a> is good for air conditioner and refrigeration systems and compatible with all refrigerants and oils. We liked that it was designed by HVAC professionals after a decade of research and that it is made in the U.S.A.<\/p>\n

    We found that it is easy to use and injects with no problem. Keep in mind that the product is only the leak sealant, so you will need a standard manifold gauge set to inject it. On the downside, this product is meant for small leaks, where you haven\u2019t lost more than 15-20% of your total charge.<\/p>\n

    This is marketed as a permanent leak sealer and is not recommended for systems that hold less than 10 ounces of refrigerant. One Leak Saver will work for systems of up to five tons (60,000 BTU). They stand by their product and offer a 100% satisfaction guarantee.<\/p>\n
