Full line of Spectroline fluorescent leak detection dyes is formulated for oil-based industrial fluid systems, including hydraulic fluids. Dyes are available in a choice of seven colors (yellow, white, green, bright blue, yellow-green, blue, and red) to help differentiate between leaking fluid systems, especially those leaks where portions of the hoses are hidden from view. They will not damage the fluid’s properties nor the system’s components. They are are filtered down to 2 μm.
