Hard-to-Find Hydraulic Leaks Are Easy to Find


Maintenance specialists no longer have to fret over elusive leaks in oil-based lubrication and hydraulic systems. Spectroline® OIL-GLO™ 22 fluorescent dye will pinpoint leaks in all types of industrial equipment, including milling and injection-molding machines, hydraulic tanks, fork lifts, gear boxes, punch presses and other equipment that use hydraulic fluids.

Fluorescent leak detection is fast, easy and precise. Just add a small amount of OIL-GLO™ 22 dye
to a hydraulic system and allow it to circulate for several minutes. Wherever there is a leak, the dye escapes with the oil and accumulates at the site of each and every leak. Then scan the system with a high-intensity Spectroline ultraviolet or UV/blue light lamp and the dye glows a bright yellow color to clearly reveal the exact location of all leaks — even small leaks undetected by other methods.

After the leaks have been repaired, scan the system again with the lamp. If there is no glow, it means that all the leaks were fixed properly.

OIL-GLO 22 remains safely in the system until the oil is changed, making it ideal for preventive maintenance. Periodic inspections with the lamp will detect any future leaks before they can cause damage to the equipment.
