Designed for direct injection into a pressurized system, the formula moves with the refrigerant and reacts at leak sites to form a durable seal. It is made in the USA and engineered to be compatible with a wide range of refrigerants and system components, offering technicians and DIYers a fast, less-invasive option for leak control and preventive maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly does Leak Saver stop a small refrigerant leak?\u003c\/h3\u003e\n\u003cp\u003eIn systems where the refrigerant charge remains mostly intact, Leak Saver typically completes a seal within seven days of circulation. Results depend on leak size, system pressure, and airflow across the evaporator or condenser, but most small leaks will show closure in the first week.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTypical time to seal: up to 7 days under normal operation.\u003c\/li\u003e\n  \u003cli\u003eWorks while system runs—no long downtime required.\u003c\/li\u003e\n  \u003cli\u003eMost effective on small pinhole or hairline leaks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this product work with my HVAC or vehicle air conditioning system?\u003c\/h3\u003e\n\u003cp\u003eLeak Saver is compatible with nearly all modern HVAC and refrigeration equipment, as well as most automotive AC systems, excluding ammonia-based systems.
