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.
Leak-Detecting Dye Kits for HVAC Systems
With bright-colored dye and a fully equipped kit, you have everything you need to spot leaks in your HVAC system. These kits come with the correct amount of dye required for your system's size. Inject the dye into your system and scan it with the UV light—the dye is fluorescent, so it’s easy to spot most leaks right away. For small leaks, let the dye circulate for 24 hours and then inspect it again. Use the dye cleaner before you fix a leak. If the repair isn’t sufficient, you’ll be able to spot more dye.
Kits with UV dye and sealant are formulated to seal hard-to-find leaks from the inside of your system. The dye and sealant formula is non-polymer and oil soluble, making it safe to stay in your system indefinitely. Reinforce seals from the outside for a permanent fix.
Kits that meet ANSI/ASHRAE adhere to standards for chemical stability.
Kits that meet SAE J2297 include dye that was originally made to detect leaks in automotive AC systems.

Marking Fluids
Stain metal items such as bearings, springs, nuts, and other components. These fluids repel oil, adhere without flaking and scaling, and won’t interfere with part performance.
Opaque fluids conceal the color of the part.
Transparent fluids allow the color of the part to show through and are thinner and dry faster than opaque fluids.
Fluids that cannot be sold to the listed areas exceed local regulatory limits on VOCs (volatile organic compounds).
High Spot Blue Marking Paste
Identify high spots, interference points, and improper fit on bearings, gears, and valves. Apply this blue paste, also known as engineers’ blue, to parts or components and assemble them into working position. Any improper fit will show up as a blue streak. Paste cannot be sold to the listed areas because it exceeds local regulatory limits on VOCs (volatile organic compounds). Remove paste with Marking Fluid Remover.

Colorants for Plastic Pellets
Add color when making plastic parts. Also called masterbatches, these colorants contain a base plastic that works with a variety of plastic types—from general purpose polypropylene to tough ABS. This means you don’t need to stock up on colorants for each type. Mix them in with your pellets before melting. To get a rich color for most plastic, you need only 1-2% of colorant in your batch, since they’re concentrated.
