Super Tech Auto R-134a Refrigerant with Stop Leak, Self-Sealing Can, 3 oz, Pack of 1

My only difficulty was in finding a compatible hose in order to use it. Standard hoses won't fit my car. You would think a Civic would be easier to get a hose for.

Great product for a pinhole leak. Easy to install but you will need the can adapter which is very reasonable. The can adapter is for the new EPA self-sealing R134A. Perfect!

Product seems to be working. Installed one can of this product along with one 12 ounce can of freon and the ac is maintaining the pressure.

I have used this stop leak on 3 different vehicles over the years and it's worked everytime. It does stop minor leaks in the AC system!

Really hard to say that this 100% was the fix for my leak. I had a really bad leak in my Chrysler T%26C - filled with R134 and it leaked out overnight. Looking online, I took a gamble and blocked off the rear portion of the system, since that seemed to have the most conversations about the source of the leak. I vacuumed the system after blockoff, and that held for less than 5 minutes. Frustrated and desperate, I turned to this stop leak product. Bought 2 cans and loaded them in. The charge seemed to hold overnight, so I loaded some r134 in over a couple days. It lasted through our 700 mile road trip over the holiday weekend, so I think the stop leak worked - although I have heard of systems that have a vacuum leak, but pressure will hold, not sure how true that is.

I didn't realize it was the 3 oz can for 798 12 oz can another storage cost between 10 and $13 and even after the total my bill was $38 which should have been more closer to 28

Decided against using It after some thought. If it's not factory installed (leak sealer) it don't belong! Fix it right. How this stuff doesn't clog sensitive sensors and the like Come On Now! It may work but I'll pass. I'll keep the purchase my mistake.

Way to small of can I had no idea that I was getting a miniature version of the original super tech refridgerant134a in 12oz can what I expected. This isn't what I thought at all they haven't been even messed with I just want to return for refund to my card. Thanks and if you sell anything total you had better thank god cause it ain't no big thing it's only 3ozs. Be for real want just return it for a free location

Maybe it's me my dispensing gauge in hose that pierces the cans. It's the cheap original that came with a cans at 20 years ago pierced the regular size cans just fine but when I went to put stop leaking a different vehicle the same day it wouldn't pierce either can of the two pack of the refrigerator with oil

Used in myChevy S 10 Feb 25, 2025. Only about half of the can of Freon stop leak was injected into my system. About half remained in the Can. I continued to service my system with regular Freon. The whole can of regular Freon was injected into my system. Possibly? was the Can blocked or not enough pressure to inject into my system? I filed a return with WALMART.This is the first time I've use this brand. As of now I would not recommend. MT GRAHAM, Mesa, AZ,USA.
