Clear DEF™ Diesel Exhaust Fluid

Diesel Exhaust Fluid is a purified solution of 32.5% urea in deionized water. It is a colorless, odorless, non-hazardous, non-flammable solution made from natural gas. In an effort to protect our natural enviroment, DEF is injected into the exhaust system of Selective Catalytic Reduction (SCR) equipped diesel vehicles to convert noxious NOx into harmless nitrogen gas.
