DEF at A&I Distributors

We help our customers’ diesel engines run cleaner and smoother. A clear, non-toxic, and non-flammable fluid, Diesel Exhaust Fluid (DEF) is made of purified water and urea. A&I Distributors offers DEF products to help reduce the amount of harmful pollutants released into the atmosphere from diesel engines.

Cleaner Engines

DEF helps diesel engines meet the strict emission standards set by the Environmental Protection Agency (EPA) and other regulatory bodies around the world. Injected into the exhaust stream of diesel vehicles, DEF reacts with harmful nitrogen oxides to convert them into harmless nitrogen and water vapor.
