Its been 4 months & multiple 3 digit days here in the south & all of our Gauge Readings have held up as well as Delta T & the Superheat recommended by the manufacturer....I'm VERY impressed & I honestly, in the beginning, felt like this would end up being more "snake oil". I'm a certified Universal 608 holder but I am an AMATEUR. I've heard claims of long term negative affects & even that its "idiotic" to use this in the first place. I couldn't verify any of that in this review because my experience in HVAC doesn't hold as much knowledge as a long time professional but I can say that in a very difficult financial situation this really worked for me and my family. Review: Excellent Product – Easy to Use and Effective - Excellent Product – Easy to Use and Effective. I’m an HVAC technician and this product worked exactly as expected. Easy to inject, no issues during installation, and it helped seal a small refrigerant leak quickly. It saved time and avoided a costly repair for the customer. I would definitely buy it again and recommend it to other HVAC professionals. ## Features - THE EASIEST INJECTION METHOD: No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver injects directly and easily into the system with a basic manifold gauge set or even easier with our Leak Shot Injection Kits. Note: for automotive systems, you will still need the standard 134A to 1/4” charging adapter. Mini-splits may require a 5/16” to 1/4” charging adapter. - MORE THAN 3 MILLION UNITS SOLD SINCE 2015: The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 72 hours. It’s similar to how blood in your body reacts to a cut. When a leak occurs, the Leak Saver reacts with the air and moisture at the leak site to permanently seal the leak. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks. - WITH ADDED UV DYE FOR FINDING LARGE LEAKS: Seal it or find it! If you have a leak that is simply too large for leak sealants to seal, the added UV Dye will light up brightly at the leak site when using a UV flashlight. - COMPATIBLE WITH ALL SYSTEMS AND REFRIGERANTS: : The Leak Saver UV is compatible with all systems, refrigerants (except ammonia), and oils. It is great for central air conditioners, car and automotive air conditioners, refrigerators, ductless mini-splits, heat pumps, geothermal heat pumps, commercial refrigeration systems, micro channel coils and more. It also works with all refrigerants including R410A Freon, R22 and replacements, R134A, r1234yf, R404A, R290, R600a, and more. - YOUR SATISFACTION IS OUR PRIORITY: We stand behind the effectiveness 100%.

I’m an HVAC technician and this product worked exactly as expected. Easy to inject, no issues during installation, and it helped seal a small refrigerant leak quickly.

I would definitely buy it again and recommend it to other HVAC professionals. ### ⭐⭐⭐⭐⭐ I'm an HVAC technician *by K***8 on December 22, 2019* The reviews I read before purchasing this can be pretty scary if you're the average homeowner. Some say the compressor failed as a result. That is because this type of product is designed to be a liquid that flows with the refrigerant until it meets with oxygen and moisture. These conditions should only be met in the crack where the refrigerant leak is, but can also happen if technicians that have worked on your system did not purge their hoses or if the leak is on the suction (low pressure) side of the refrigerant circuit and the refrigerant level was very low. That being said, if you use this yourself, be sure to do 2 things. 1) Be sure to purge the hose with refrigerant before letting the product into the suction service port. 2) MOST IMPORTANTLY --- before you even open the package, buy and install a drying agent a few days before installing this product. Also, do this during the cooling months so that the drying agent has a chance to circulate and mix evenly throughout the system. That will remove any moisture from your refrigerant and greatly reduce the risk of your compressor failing after the installation. This seller also sells the drying agent which is the one I bought. Using a product like this is always a risk which is why it should only be done as a last ditch effort to keep an old leaky but efficient system running. Your compressor may die by using this and that's not this manufacturers fault. I just used this on my own house and it still runs. ALSO, this may not stop the leak if it is a very large leak. It works best on systems that have to have 1-3 pounds a year added. My leak was faster and I think it slowed the leak down but I haven't verified with a legitimate leak check yet. I'll check again in the spring. It takes a year to really know if it worked. My leak is in my evaporator coil which is the most common place for any brand of cooling system. So far I am satisfied with this product. I am curious to check and see how much refrigerant is needed this spring and if it worked or not. I'll try and update this review. A last thought is that I don't thing the UV dye in this kit works very well or at all but the sealing agent might work. Again I'll try and update later. ## Frequently Bought Together - Leak Saver Direct Inject UV - Refrigerant Leak Sealer with Added UV Dye to Detect Large Leaks - for AC, Refrigeration, and Automotive Systems Up to 5 Tons - Compatible with All Refrigerants - Leak Saver AC Drain Line Cleaner Tool & Leak Sealant Injector | Condensate Line Co2 Drain Gun | AC Drain Line Unclogger - Leak Saver Direct Inject Ultimate 3-in-1 | AC Refrigerant Leak Sealer | with UV Dye & Moisture Remover | for Most HVAC Systems Up to 5 Tons - Professional AC Leak Sealer - AC Stop Leak --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/56166398-leak-saver-direct-inject-uv-refrigerant-leak-sealer-with-added](https://www.desertcart.sc/products/56166398-leak-saver-direct-inject-uv-refrigerant-leak-sealer-with-added) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-06*
