ADDED UV DYE: 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.

STOP LEAKS PERMANENTLY: Permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 7 days. Our AC stop leak formula reacts with the air and moisture at the leak site to permanently seal the leak. If you suspect your system to have moisture, we recommend that you first inject our LEAK SAVER DRY MOISTURE REMOVER. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks.

WORKS WITH ALL SYSTEMS: Compatible with all systems up to 5 Tons (60,000 BTU, 17.6kW). It is great for central air conditioners, car and automotive air conditioners, refrigerators, ductless mini split, central AC, home refrigerator, boat, RV, ice machine, chiller, refrigeration racks, heat pumps, geothermal heat pumps, commercial refrigeration systems, micro channel coils, and more. Leak Saver Direct Inject works on all car and auto air conditioners, RV, boat, car, truck, automotive systems.

WORKS WITH ALL REFRIGERANTS: Direct Inject refrigerant stop leak formular works with all refrigerants (except ammonia), and oils. Including R410A Freon, R22 and replacements, R134A, r1234yf, R404A, R290, R600a, and more. Safe for all HVAC tools, AC repair tool, manifold gauges, hoses, expansion valves (TXVs, TEVs, capillary tubes, etc), Schrader valves, and anything needed to service your system.

EASY INSTALLATION: 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. You can see our straightforward installation videos above.
