Formulated specifically for large-capacity industrial systems, Oil-Glo 44 is a blend of two different fluorescent dyes. One fluoresces best under ultraviolet light and the other fluoresces best under blue light. As a result, regardless of the type of inspection lamp used, the dye will glow brightly to reveal small and elusive leaks. It can be used to pinpoint leaks in all oil-circulating systems.
