Supporting high-volume leak detection in R-1234yf and R-134a systems, this 8 oz (227 g) (237 ml) universal ester dye cartridge contains enough fluid to treat up to 64 vehicles. The formulation remains safely within the A/C components after the initial service is performed, allowing the dye to function as a permanent part of a preventative maintenance program. Because the solution does not damage system internals, it stays active to pinpoint future leaks during routine inspections.
