## Features

- 3-IN-1 SEALANT + MOISTURE REMOVER + UV DYE – Our proven leak sealant now includes moisture remover and UV dye for the complete system treatment! Now, you can seal your leak, remove system moisture, or find large leaks with the UV Dye...all in one easy to install package!
- STOP LEAKS PERMANENTLY - The Leak Saver can permanently seal refrigerant leaks where the complete refrigerant charge is not lost within 7 days. 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
- WORKS WITH ALL SYSTEMS & REFRIGERANTS INCLUDING CARS - Our product is compatible with all systems, refrigerants (except ammonia), car refrigerants, and oils. It is great for central air conditioners, 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
- STRAIGHTFORWARD INSTALLATION - No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver HVAC sealant 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. You can see our straightforward installation videos below
- SAFE FOR ALL TOOLS AND PARTS - Our HVAC leak sealer is safe for all manifold gauges, hoses, expansion valves (TXVs, TEVs, capillary tubes, etc), Schrader valves, and anything needed to service your system. Adapter required for mini splits (5/16" to 1/4") and automotive systems ( 134A to 1/4")
- THE MOST TRUSTED - The numbers don’t lie! With more than 4,000,000 units sold of our air conditioner leak sealer formula since 2015, we are the most trusted leak sealant among HVAC professionals. Proudly made in the USA. We stand 100% behind the quality of our products. If for any reason you are not satisfied with your order, reach out to us and we will make it right.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Stopped a small car evaporator leak
*by C***N on August 10, 2025*

Stopped a small leak in car A/C evaporator where other products had failed. Note this product has 1/4” male and female connectors on each end. To use in a typical auto system, you will need to purchase a 1/4” to R-134A convertor kit (or at least 1/4” to 1/2” adapters). A hose and gauge manifold set is also highly recommended to ease injection. Many auto parts stores will rent them out for the day if you don’t want to invest in a set.

### ⭐⭐⭐⭐⭐ Works well, just for what it is seems expensive.
*by D***W on July 12, 2025*

Seems to have helped with our residential split system. Was easy to use vs others and can't say if the UV worked as I never found any simye so maybe the leak sealent fixed anything that might have leaked.

### ⭐⭐⭐⭐⭐ Works as advertised
*by J***S on July 31, 2025*

This leak fixer allowed me to plug a small leak where I made a flare connection. I had lost all the refrigerant during the first try. Then I redid the flare connection, recharged the unit while using the leak stopper. It leaked a bit at first but then it stopped leaking. The HVAC appliance works now.Definitely recommend the product.
