Chemistry. Diesel exhaust fluid (DEF) from a separate tank is injected into the exhaust pipeline, where the aqueous urea vaporizes and decomposes to form ammonia and carbon dioxide. Within the SCR catalyst, the NO x are catalytically reduced by the ammonia ( NH 3) into water ( H2O) and nitrogen ( N 2 ), which are both harmless;
The Consumable Fluid. Diesel exhaust fluid is a mixture of synthetic, high-purity, automotive-grade urea and deionized water. This liquid is clear, nontoxic, nonflammable, non-explosive, and generally nonhazardous. Additionally, DEF is classified as a minimum risk for transportation.
Diesel Exhaust Fluid (DEF) is a non-hazardous solution, which is 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. This system is called Selective Catalytic Reduction (SCR)...
Reduce emissions and keep your diesel vehicle running clean with diesel exhaust fluid (DEF) from AutoZone. We sell the best brands, including AutoZone, Lumax, and Peak Blue DEF fluid. We also sell accessories, like a DEF pump, nozzle, flow meter, or coupler.
Diesel Exhaust Fluid is formulated with 32.5 percent urea and 67.5 percent deionized water. In storage or when the engine is not in use, DEF will freeze at 12°F (-11°C). At this concentration level, the urea and the water freeze and thaw at the same rate – ensuring that you always have the correct amount of each.
Order Diesel Exhaust Fluid for your vehicle and pick it up in store—make your purchase, find a store near you, and get directions. Your order may be eligible for Ship to Home, and shipping is free on all online orders of $35.00+.
Diesel exhaust fluid is used to reduce NOx emissions. You will get a lot of warnings to refill the DEF tank before you run out. If you decide to ignore the warnings or the circumstances do not allow tank refill, the engine is designed to limit its power and fuelling dramatically.

The Story of Diesel Exhaust Fluid. The DEF is injected into the diesel exhaust stream where it reacts with a chemical catalyst to convert NOx into a harmless gas. DEF is API certified and meets ISO22241 specifications. Diesel Exhaust Fluid is non-toxic, non-flammable, colorless, non-hazardous, and very easy to use, and applies to vehicles produced since 2010.
Buy diesel exhaust fluid at Grainger and help selective catalytic reduction (SCR) diesel engines meet the EPA’s near-zero emissions requirements. The after treatment for this new technology allows vehicles to be optimized for performance and fuel economy.
