Oil-Glo 40 pinpoints leaks in synthetic- or petroleum-based fluid systems, including light-colored hydraulic fluid, very dark or intensely blue hydraulic and lubrication fluids, compressor oil, engine oil and gearbox oil. Wherever there is a leak, the dye escapes with the system oil and remains at the site. Scan the system with an ultraviolet lamp and leak glow bright blue.
