BlueDEF DEF002 Diesel Exhaust Fluid, 2.5 gal, Liquid, Ammonia

BlueDEF™ Diesel Exhaust Fluid is a mixture of high purity Synthetic Urea and Deionized Water that is used in selective catalytic reduction (SCR) systems in Diesel vehicles. DEF is used to help convert NOx to harmless Nitrogen and Water. Diesel Exhaust Fluid (DEF) is one of the key elements of the selective catalytic reduction (SCR) process used by Diesel engine builders to meet EPA 2010 regulations. BlueDEF™ is a non-toxic solution of 67.5% Purified Water and 32.5% ultra-pure automotive-grade urea. BlueDEF™ is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, BlueDEF™ helps convert NOx into Nitrogen Gas and Water Vapor two harmless and natural components of the air we breathe.
