DEF is a nontoxic solution made up of purified water and pure automotive-grade urea. DEF is not a fuel, or fuel additive. In a Selective Catalytic Reduction system, DEF is injected into the tractor exhaust stream through a controlled ‘dosing’ module which varies the application rate. The DEF fluid vaporizes NOx emissions and converts them into harmless nitrogen gas and water vapor–natural components of the air we breathe.

Cost may change without notice, while supplies last.
