The UV Dye Kits & Injectors category includes the specialized tools HVAC technicians use to inject fluorescent dye into refrigerant lines for tracing and confirming leaks. UV dye offers a highly effective visual method for locating leaks over time, especially in concealed or hard-to-reach system components.
This section includes dye injector guns, syringe-style injectors, dye cartridges, hose-connected injectors, UV dye compatible with R-22, R-410A, R-32, R-454B and other blends, as well as kits that bundle injectors, hoses, adapters and UV inspection tools for complete leak-detection systems.
When selecting UV dye kits and injectors, check dye type, refrigerant compatibility, injection method, hose fitting size, system capacity and included adapters. Using the correct dye and injector prevents over-dosing and ensures smooth injection into the sealed system.
Pro tip: Use small-dose syringe injectors for mini-splits, and cartridge-style guns for larger residential and light-commercial systems. Always follow dye volume guidelines—too much dye can reduce lubrication quality and affect system performance.
