One unit handles three of the most common service needs: sealing small refrigerant leaks, removing system moisture, and locating large leaks with UV light. Over 3 million units of this sealant formula sold since 2015.

The moisture remover eliminates the need for a separate Leak Saver Dry treatment. The UV dye means that if the leak is too large to seal, you can still locate it with a UV lamp rather than leaving the job unresolved.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs one unit enough?\u003c\/strong\u003e\u003cbr\u003e\nOne unit treats systems up to 5 tons (60,000 BTU). For systems between 5 and 10 tons, use two units.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it safe for my TXV and expansion valves?\u003c\/strong\u003e\u003cbr\u003e\nYes.

The sealant reacts chemically at the leak site to form a durable bond. Unreacted sealant continues circulating to seal future leaks.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use this on an R454B system?\u003c\/strong\u003e\u003cbr\u003e\nYes.

If you don't have one, the sealant and moisture remover functions work regardless. A UV lamp is only needed if you need to locate a leak that was too large to seal.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat if my system has a lot of moisture?\u003c\/strong\u003e\u003cbr\u003e\nThe Ultimate includes a moisture remover, which handles typical moisture levels.
