Leak-Detecting Dye for Hydraulic Systems
Easy-to-see colors enable you to visually inspect for leaks.
Use 1 fl. oz. of dye for every 50 gallons of oil, solvent, wax, or other industrial fluid you're inspecting.
Fluorescent dye can be enhanced with a UV flashlight.

Leak-Detecting Dye for Water Systems






Easy-to-see colors enable you to visually inspect for leaks without ultraviolet light.
One gallon of water occupies 0.1337 cubic ft. Calculate the number of gallons a tank holds by dividing the tank volume by 0.1337.
Fluorescent dye can be enhanced with a UV flashlight.
Tablets are easy to use for small volumes of water, such as toilets and septic systems. They dissolve in five minutes. Tablets that come in a packet include instructions for detecting a toilet leak.
Liquid is a good choice for larger volumes of water, such as sewers. It disperses faster than tablets and powder.
Powder is the best choice for the largest volumes of water, such as ponds, piping systems in power plants, and cooling towers.

Leak-Detecting Dye for Gasoline and Diesel Fuel Systems



Detect leaks in fuel systems and storage tanks. Add this fluorescent yellow dye to your system and use a UV flashlight (sold separately) to illuminate leaks. Use 1 fl. oz. of dye for every 10 gallons of fuel.
UV Light Flaw-Detection Kits
More sensitive than natural light kits, these kits use UV light with colored dye to detect cracks, seams, and pores on machined surfaces.
