Features

  • STOP LEAKS PERMANENTLY - The Leak Saver can permanently seal small 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 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
