Leak Fluorescent Dyes

Oil-soluble and water-soluble tracing dyes for rapid, reliable leak detection.

LUYOR fluorescent tracing dyes are the partner to our detection lamps—engineered to circulate safely through your system and glow brilliantly at the exact point of escape. Available in oil-soluble and water-soluble formulations to match your system fluids.

Choose your formulation, choose your volume. 

Available in the LUYOR-6100, LUYOR-6200, and LUYOR-6300 series—with multiple volume options to suit single-use applications, routine maintenance programs, or bulk workshop supply.

How it works:

Add the dye to the system, run it briefly, and scan with a LUYOR fluorescent detection lamp. Any leak—no matter how small—glows brightly at the source.
