Compatible with R-12 and R-134a systems, it forms a chemical weld at leak points, conditions internal parts, and includes UV dye for easy leak detection—trusted by DIYers and pros alike. ## Description Red Angel A/C Stop Leak is a professional‑grade, permanent solution designed to seal leaks in automotive air conditioning systems without clogging or damaging components. This advanced formula activates only at the leak point, forming a durable chemical weld that seals leaks in condensers, evaporators, hoses, gaskets, and O‑rings while remaining inert throughout the rest of the system. It is safe for use in R‑12 and R‑134a systems and is commonly used for both repairs and preventative maintenance. Formulated with no solids or particulates, Red Angel A/C Stop Leak will not crystallize or interfere with moisture, oxygen, or A/C recovery equipment. In addition to sealing leaks, it conditions and lubricates internal components to help extend system life. The included UV dye simplifies leak detection and verification, making it a trusted solution for DIY users and professional technicians alike Review: Works great - Works great highly recommend this product Review: temporary fix did not actually saved me hundreds but cooled me temporarily for the summer - 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 ## Features - Remarkable ability to repair and seal leaks in condensers, evaporators, connection hoses, gaskets, and O-rings - Contains no solid or particulate matter that will clog the A/C system, or harm a recovery unit - Forms a chemical weld sealing leaks in both R-12 or R-134a systems - Safe to use and best of all — it’s a permanent seal - Guaranteed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NSRVP6A | | Best Sellers Rank | #11,183 in Automotive ( See Top 100 in Automotive ) #43 in Air Conditioning Line Repair Tools | | Brand | BlueDevil Products | | Customer Reviews | 4.3 4.3 out of 5 stars (842) | | Date First Available | September 24, 2014 | | Item Weight | 1.76 ounces | | Item model number | 49496 | | Manufacturer | BlueDevil Products | | Manufacturer Part Number | 49496 | | Model | 49496 | | Product Dimensions | 0.9 x 2 x 3.9 inches | ## Images ![BlueDevil Products Red Angel Automotive A/C Stop Leak & Conditioner | 2 oz. - Image 1](https://m.media-amazon.com/images/I/71t5gs3bNXL.jpg) ![BlueDevil Products Red Angel Automotive A/C Stop Leak & Conditioner | 2 oz. - Image 2](https://m.media-amazon.com/images/I/61s0+zIDHYS.jpg) ![BlueDevil Products Red Angel Automotive A/C Stop Leak & Conditioner | 2 oz. - Image 3](https://m.media-amazon.com/images/I/81so33tOfPL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is it okay to use this if I have green dye in the system ?** A: Why not? **Q: is this for car A/C?** A: Yes. I had Red Angel AC Stop Leak added to my 1993 Toyota 4x4 back in June 2014 and is still operating ice cold . My dealer diagnosed the leak to be behind the dash with either the O-rings in the connections or the evaporator. The cost for repair was estimated at over $1200. I definitely recommend Red Angel A/C Stop Leak (49496) if your AC meets the leak requirements listed: If your vehicle can hold 5 inches of vacuum for 25 minutes or 15 inches of vacuum for 5 minutes. This product is not recommended for systems that lose more than 1 pound of Freon per day or leaking compressors. **Q: Is it possible this is compatible with enviro safe refrigerants? (A 134a replacement/ runs much colder)** A: Late to answer but yes this will work with r134a drop in replacements. I’ve used it with two different hydrocarbon based r134a replacements, like envirosafe and frosty cool. **Q: Can it be on refrigerators?** A: YES, BUT ONLY A SMALL AMOUNT AS THE REFRIGERANT CAPACITY IS SMALL.
