Red Angel 49496 A/C Stop Leak - 2 Ounce

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 !

update new review : i was happy with the product because its held up pretty well for 2 month, after that month the a/c stopped working, and i had to replaced parts on my vehicle to fix the a/c problem and it damaged my pressure sensor due to the sealer. so overall the product only temporarily fixed my issue olds review: I'm very please with this product, I was having problems with my ac system last year and all the refrigerant leaked out within a couple of day after charging the system on my vehicle, i checked to see if any leaks were present and we not able to find a leak even with dye on the system. My thought were that the evaporator was leaking. I saw some good reviews and bad reviews about this product so i went ahead and gave it a try since the product had over 4 stars. i recovered my ac system and vacuum the system for 30 minutes, i installed the red angel a/c stop leak 2 ounce liquid in the a/c system before recharging the system, after i recharge the system with the refrigerant and ran the a/c for at least 15 minutes more like 30 minutes as instructed by the instructions. Its been about a month an a half and the a/c system is working like a champ. Ill be coming back to update my review and to let everyone know how good this product has worked for me

Expensive product that only lasted a week. My AC worked for a week and then leaked all the Freon. The product doesn't deliver what it promises.

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

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.

Works good for low side leaks. This will not work for a bad hose, faulty compressor seal, or a hole in the condenser. I have been using this for years with good results. UNFORTUNATELY THEY HAVE "DISCONTINUED " THE 8 OUNCE TUBE. GREAT CUSTOMER SERVICE PINK DEVILS.

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!
