InterDynamics Certified A/C Pro Super Seal Car Air Conditioner Refrigerant Stop Leak Kit, Repairs Metal Leaks and Seals Rubber Leaks in O Rings and Hoses, Includes Reusable Dispensing Hose, 3 Oz, InterDynamics

My old car's ('03 Subaru ) AC developed a leak where it would stop working within a couple days of a refill. I tried some other similar stop-leak products but only meant for worn seals etc that had the refrigerant included without success. The estimate for repairs was $900 which is more than I was willing to fix a car I intend on replacing soon. **The text on the packaging does explicitly state that the product is not appropriate for a leak was fast as mine** I decided to give this stuff a try and immediately refilled the AC unit after as instructed, much to my dismay (and no surprise) the AC stopped working again within days and I gave up. I decided that I would add $4.50 refrigerant before the next few road trips and start shopping for a new car before I create a new hole in the ozone layer. A week later I needed the car and it was very hot out so I refilled the AC again expecting it to stop working within a couple days again and here I am over 5 weeks later and the AC still works! I've delayed buying a new car because of this. EDIT: 1.5years later and still holding up! It might not work for you but it’s certainly worth trying. Edit June 2019: 2 years later and AC still works! A little less cool this summer but will add some refrigerant soon

My son and I are restoring a black and red 89 Iroc z. Cool-looking, but murder in the summer sun. The seller swore that the AC worked, but it had a leak, and he wasn't kidding. Fully charged, the AC worked great. But after bringing the charge up to mid-level with three 12-oz cans of replacement R134a, the system was down to near zero in one or two days. And it's 90+ here in Maryland with 70-95% humidity. And we're saving our pennies for good headers, not AC (yet). And in this weather with crazy humidity and sudden thunderstorms, opening the T-tops doesn't cut it. What to do, what to do............... So after reading the reviews, we tried this ID brand sealant. I wasn't hopeful, because our leak was major. But we hoped to limp by until cooler fall weather, and then do major repairs next spring. Three weeks later, the AC is still blasting out cold air and the charge level appears to be spot-on. I added this leak stop and then another three 12-oz cans of R-134a. IMPORTANT: If you have a can tap with a slash tip that punctures the top of an R134a can, it won't work with most leak-stop cans. So buy this one because it has the correct can tap, which uses a pin to push down a valve in the can. Eventually I'll have to buy a compressor kit with the dryer and piping, and also a vacuum pump. But for now, this stuff seems to have saved our keysters, allowing us to focus on more engine mods.

I've done a lot of my own auto work over the years and have taken a few automotive classes at the local community college. I followed the directions impeccably, including the recharge can after the leak sealer. My AC had been weak and was slowly leaking into the cabin. One day after the leak sealer my AC was completely shot. Almost certainly clogged/gummed up. Local dealer flushed it, recharged it, and it's still completely shot. Now we're looking at replacing one expensive part after another (starting at $1200 compressor) hoping that one of them fixes it. Use this at your own extreme risk.

I put it in a window a/c unit. It blew a bunch of foam looking stuff out of the hole and then dried up a sealed in the hole. Hasn't hurt the compressor and it's still sealed. Has been a couple of weeks so far

I was holding off from writing this review; I didn't want to jinx the success. Three week after using it and still going strong. Another reason for not writing a review you see, rating up products on Amazon tend to send up the price; but customers should also benefit from its use. This product works. The product information strongly suggest using it on leaks that last at least two weeks; my AC system leaked in three days. I was desperate; I identified leaks on the evaporator and dryer. I was also told the compressor shaft seal had a leak. Compressors are very expensive not to mention the installation cost, and to vacuum, gas and oil $$$$$$$$. I fixed the leak on the evaporator and dryer (small money), but the system still leaked from the compressor shaft seal. What makes this product exceptional is its use on metal, unlike other AC seals. After identifying the sole leak was from the compressor seal, I then used the super seal. It helps to know exactly where the leak is for larger leaks to achieve success.

Classic case of the warranty expires and 2000 miles later something expensive breaks. I tried it on a slow leak (2-3 weeks between charges) my regular mechanics couldn't fix for less than $2k - evaporator coil leak inside the dash. They actually recommended I have the dealer do the job! I followed all the directions to the letter, but his product didn't work for me, and may have clogged the condenser. After so many evac-refills I don't doubt there may have been some contamination in there already. However the dealer fixed that too for less than the original quote, after three weeks of, "Let's try this next, it might be a sensor here." In other words I got lucky this time, but would try it again versus a multi-thousand dollar repair!

product leaked out as I was screwing on hose. I wasn't able to get any into the A/C low pressure take off. Also ruined the blacktop on my driveway. made a huge raised orange stain. Hose must have been defective. I am asking for a replacement can. We will see if they do it or not. Update: Amazon sent me another can within a couple of days of my request. Thank you Amazon. My rating has gone from 1 star to 5 stars. Product didn't leak this time and appears to have fixed my A/C. Good product. Also my wife scrubbed the area where the product had leaked over the driveway with Dawn detergent and now the stain has been greatly minimized.

This stuff is great, I had a leak on My 2015 Chevy Silverado AC, I went to the dealer and had them check it out it cost me $250 for them to test and find the leak they said it was my condenser and it would cost $1000 to replace, I tried to recharge it myself but the charge only lasted 2 days. I did this several time before I searched and found The AC Pro super Seal, I read the reviews and decided to give it a shot, I was skeptical since my leak would not hold for more than 2 days but for the price it was worth a shot, it has been a 5 weeks (in the middle of July) and my truck AC is still working great. I would highly recommend trying this product.

Waist of money. Doesn’t work

It only works with stock genuine parts, and small leaks, If you have an aftermarket compressor, products like this will never work, and if the leak is coused by turning the car ac ON while the engine's RPM is above 1200 RPMs, than the damage well usually be without repair and products like this will never work.

Había probado con uno de Autozone stop leak y no me sirvió , y también tiere a la. Basura la recarga, lo recomiendo

Year 2022 my car ac was leaking refrigerant, applied this product and worked for a year, 2024 leaking again and applied this product, working for a week now hope it will last longer this time..
