The BigEZ dye injector contains enough fluorescent dye to treat air-conditioning and refrigeration systems containing up to 16 gallons of lubricant. This tool features a disposable dye cartridge, which is calibrated in 1/8-ounce increments, so a technician can add the exact amount of dye for each system by simply turning a handle. The BigEZ multi-dose dye injector eliminates pouring and measuring dyes. The device consists of a handle and threaded shaft and collar assembly; a disposable cartridge pre-filled with four ounces of Ar-Glo fluorescent leak-detection dye; and a hose assembly with a low-loss fitting. Ar-Glo dye is solvent-free, and exactly matches the lubricant in the system, so it will not affect lubricant properties that could cause excessive wear to system components.
