Red Angel A/C Stop Leak

I evacuated my old car a/c system, put this product in quickly before air could get into the system through the leak. It has been 6 months of Florida summer and it is still leak free and working good. I didn’t think it was going to work, but it still surprises me how well it is holding up.

Finally got around to using this product at the end of August. 2015 Nissan Versa for reference. Had a very small leak causing Ac to blow hot within 1.5 months. True Evac and recharge on the small system. Followed the directions and No issues after 1 month. Will update review if product didnt work or caused premature failure of compressor/ac system.

I use the small tubes when the long tubes are unavailable. They do the same great job the other long tubes do . Seals and refresh . Yes they are a bit pricey for a small tube like this one , but if you have a small leak that you cant find and need to check your ac from time to time , then this is it !

This is ONLY stop leak I will use. Worked perfectly and has caused no issues.

I had a small leak that lost about 3 inches of vacuum per day. Far less than the parameters stated on the packaging, claiming this product would fix. I didnt go straight to this. I replaced all the o rings in my system. I then used refrigerant with dye to try and locate the leak. I couldnt. Spent several days searching for the dye with a black light. Then i was recommended this stuff by several people and decided to try it. This product did not fix my problem and now no shop will touch the car. Guess im replacing everything and starting over. Do not use this stuff. I should have known better. This is costing me several hundred dollars in parts.

I think it would work on a very small leak amd it worked on mine for about a week but once I parked the car for a week it leaked back out.

F150 With a fast audible evaporator leak, would leak down in about a day, after putting this in it hasn't leaked since and its been 4 months.

Love this product! Works excellently! I've used it many times! Highly recommend!

Made the leak worse 😞

Just used I auto A/C and seems to work perfectly

bought this product last june when in bullhead city az and it didnt work till the middle of july it[ was used every day]when on the way to canada then it leaked when i got to my destination purchased another in canada installed it[ end of july and its now the middle of sept] and it sealed with in 1/2 hr in bullhead there was no humidity and in canada the humidity was high enough for the a/c to drip on the pavement so i believe its definetly the humidity that makes it work even think it says on the bottle that fact [ installed #2 bottle at the end of july its now the middle of sept and is still sealed ]

I have a classic car (1984) that has a leaky AC compressor. I was refilling the r134a at the beginning of summer and within a few weeks it was all gone. I didn't want to shell out $3k for a new compressor/install, so thought I would give this a try but had little hopes of it working. I'm now going on 2 months+ of it holding the r134a, which is by far the longest I've ever seen. I don't know if it's permanently repaired, but even if I can make it through the entire summer would be a miracle. So it works!

Bloody good product!
