  • 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.

When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks.
  • OVER THREE MILLION UNITS SOLD: With over 3 million units sold of this sealant formula since 2015, we are the most reliable leak sealant among HVAC professionals. Super concentrated and made to work with all types of refrigerants, it’s compatible with all types of refrigerants and oils (except ammonia).
