It features a no-fuss direct injection method compatible with manifold gauges or Leak Shot kits, permanently sealing small leaks by reacting with air and moisture. With over 3 million units sold, it includes UV dye for quick detection of larger leaks and works with almost all refrigerants and oils, making it a versatile, professional-grade solution proudly made in the USA. ## Description 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. Review: Money is wasted. I own an appliance repair business and tried this several times. They say this product can seal any leak that takes more than seven days to leak all refrigerant. But every time I used this the system lost the refrigerant within two months. Do not recommend. Review: I used this on an Active Aqua AACH25 chiller that I use for fermentation temp control in my home brewery. The chiller developed a leak after 2 1/2 years and wouldn't cool. I was about to drop several hundred $ on a new chiller when I found some YouTube videos showing how to add refrigerant to small refrigerators. I used the Supco BPV31D bullet piercing valve to tap into the low pressure side freon line and refill the R134A refrigerant with a can tap and gauge (all purchased on desertcart), but after 4-6 weeks the freon pressure was low again so I was happy to find this product. The female end of the Leak Saver connected directly to the BPV31D, and the hose for the can tap and gauge connected directly to the male side of the Leak Saver UV. With the chiller turned off, I had enough pressure in the system to do a brief purge of the connection between the leak saver and the BPV, and then purged the connection between the can tap / gauge hose and the leak saver with freon from the can. I then pressurized the hose from the can with the BPV closed, closed the valve to the can and opened the valve on the BPV. That's all it took to empty the Leak Saver UV into my chiller's freon line. I powered up the chiller and proceeded to top off the freon to the desired pressure right through the leak saver, let the system run for an hour, closed the valve on the BPV and butttoned everything back up. It's been 2 weeks, the chiller is working great and the compressor is running quieter than ever. I will update this review in a few months to report on whether my slow leak was fixed with the Leak Saver UV. ## Features - Causes skin irritation. - Highly flammable liquid and vapour. - May be fatal if swallowed and enters airways. - 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%.

It is compatible with all refrigerants (except ammonia) and is compatible with all oils. **Q: How does the Leak Saver work?** A: After injection, The Leak Saver sealant circulates throughout the system with the refrigerant. If there is a small leak, the sealant reacts with the moisture and oxygen at the leak site to form a permanent "scab-like" seal. **Q: What do I need to install the Leak Saver?** A: To inject the Leak Saver, you will need either a basic set of manifold gauges or our Leak Shot injector. When using it with automotive systems, you will need a 134a to 1/4” adapter. Ductless mini-split systems may require a 5/16” to 1/4” adapter. **Q: What size leak will the Leak Saver seal?** A: The Leak Saver is able to seal small refrigerant leaks where the complete charge is not lost within 7 days. If this is not possible, your leak is too large to be repaired with Leak Saver. **Q: What do I do if it doesn’t work?** A: We stand behind the effectiveness. If you are not completely satisfied, please reach out to us directly and we will make it right. With more than 4 million units of this formula sold since 2015, we have a strong track record of effectiveness. ## Customer Reviews ### ⭐ Review *by J***I on 13 November 2025* Money is wasted.
