Industrial Fluorescent Dyes / OIL-GLO ULTRA UV Fluorescent Dyes

OIL-GLO® ULTRA UV Fluorescent Dyes
OIL-GLO Ultra UV fluorescent dyes are for Synthetic and Petroleum-Based Fluid Systems. Works in closed-loop circulatory systems where oil-based fluids are used.
Industrial leak detection that is ideal for use as part of a diagnostic/preventive maintenance program for industrial systems.



- User Friendly — Just add a small amount of dye to the system and let it circulate. All leaks will glow brightly when scanned with a high-intensity Spectroline® leak detection lamp.
- Versatile — Allow inspection of an entire system under virtually all operating conditions. Pinpoint the exact source of the smallest, most elusive leaks – even multiple and intermittent leaks!
- Quality — Fully miscible, non-particulate and filtered down to 2 microns. Won’t change the viscosity or lubricity of the host fluid.
- Cost Effective — Highly concentrated. Contains more active ingredients per dose than competitive dyes.
- Special Formulations — Available in several distinct colors to distinguish between different leaking oil-based fluid systems.
- Several Sizes — Choose from pint (16 oz/ 473 ml) and quart (32 oz/ 946 ml) bottles as well as gallon (3.8 L) containers. Larger sizes also available upon request.
Perfect for Lubricants & Hydraulic Leaks
Dosage Chart by Fluorescent Dye Color
Recommended starting ratios for dye-to-fluid dilution.
Dye Color | Dilution Ratio | Dilution Ratio (%) |
Blue, Green, Yellow-Green | 1 fl oz (30 mL) treats up to 25 gal (94 L) | Up to 0.031% |
Yellow, White | 1 fl oz (30 mL ) treats up to 30 gal (113 L) | Up to 0.026% |
Dosage notes: Dosage ratios are guidelines and may vary based on fluid condition, fluid color, lighting, and inspection lamp strength. Darker or naturally fluorescent fluids may require additional UV dye or a different fluorescent dye color to achieve the desired glow.
