Average Reviews:
(More customer reviews)I was very skeptical about this product sealing holes in such a high pressure system as an auto a/c but this stuff has saved me thousands of dollars. I have a 1997 Suburban that has had several small leaks for the past 2 years. This spring, however, when I had the system charged, the mechanics showed me a new leak in the rear line that was literaly pouring out. It would not hold refrigerant at all. Repairs being ruled out by the cost I decided I had nothing to lose in trying the Super Seal. I added a can and charged the system. All of the old leaks sealed up completely but the rear line still had a very small leak. I called the manufacturer to ask if perhaps a second can was recomended since my front and rear air system was about twice the average size. I was actualy told that a leak as large as mine would probably not seal. After hanging up the phone I thought "Well, it's not a large leak any more but a small one so maybe it will work", still having nothing to lose I added a second can and the leak sealed completly before I finished adding the refrigerant. It has been blowing ice cold for three weeks now and I have recently checked the pressure and found it has not lost anything at all.
This is a great product that actualy does what it claims and I would strongly recommend it to anyone who is in need of major repairs of great expense.
This is an update to the review I wrote in May: It's now near the end of September and though I don't need the a/c as often, it is still blowing ice cold. I have been on many long, family road trips this summer and the front and rear air have been fine. Having lost no refridgerant whatsover by now I feel safe in saying this has been a permanent fix.
April 22, 2010 update.... 80 degree weather over Easter weekend and a/c still blowing cold. This stuff is amazing!
July 15, 2010 update..... record hot and humid summer so far and still staying cool. Went on a long family vacation last week and my kids kept telling me they were cold every time I had the rear air too high.
August 5, 2010 update......10 days ago I noticed a fresh, wet spurt of the green Super Seal dye that had leaked out of the front of my compressor. I rinsed it off thoroughly and watched for more to show up and none has. It must truely seal new leaks as they appear because there has been no further sign of the new leak and it has been in the 90's all week and the air is still fine. Comforting to know! The compressor would have been a costly repair. I'll only mention the new leak again if there is any change but it seems unlikely.

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.
