    Dye Kit

    With bright-colored dye and a fully equipped kit, you have everything you need to spot leaks in your HVAC system. These kits come with the correct amount of dye required for your system's size. Inject the dye into your system and scan it with the UV light—the dye is fluorescent, so it’s easy to spot most leaks right away. For small leaks, let the dye circulate for 24 hours and then inspect it again. Use the dye cleaner before you fix a leak. If the repair isn’t sufficient, you’ll be able to spot more dye.
    Four 0.5 oz. UV Dye and Sealant Containers—Kits with UV dye and sealant are formulated to seal hard-to-find leaks from the inside of your system. The dye and sealant formula is non-polymer and oil soluble, making it safe to stay in your system indefinitely. Reinforce seals from the outside for a permanent fix.
    ANSI/ASHRAE Standard 86 and ANSI/ASHRAE Standard 97—Kits that meet ANSI/ASHRAE adhere to standards for chemical stability.
    SAE J2297—Kits that meet SAE J2297 include dye that was originally made to detect leaks in automotive AC systems.
