DEF Distribution and Products

Retail Availability:

DEF is now available in many travel centers across the nation. Some have DEF pumps

available and others offer pre-packaged containers of DEF in their convenience stores. 




Bulk Availability for On-Highway and Vocational Fleets:

A DEF infrastructure has been put in place to provide convenient and efficient ways for fleets to provide DEF to their operators.

DEF can be purchased for your garage or fleet headquarters in drums and totes to fit your fleet's need for DEF. 

Also, manual and electric pumps are available for DEF dispensing. 



Mobile Bulk Availability

For the vocational sector of the trucking industry, it is sometimes necessary to fill up on the

job site.  Therefore, some bulk DEF distributors have developed skid systems to make bulk DEF

more portable and able to be loaded onto a supply truck to be used as necessary on location.

Def Tankers are also available

Diesel Exhaust Fluid Fact Sheet and FAQ's - Click here for information

EPA 2010 vehicles equipped with Selective Catalytic Reduction (SCR) technology will use Diesel Exhaust Fluid.   Diesel Exhaust Fluid, also called DEF, is a solution made up of purified water and 32.5 percent automotive-grade urea that is used as a carrying agent for the ammonia needed to reduce nitrogen oxide (NOx) emissions from vehicles into nitrogen, water and carbon dioxide (CO2).

Diesel Exhaust Fluid is monitored for quality and certified by the American Petroleum Institute, ensuring that Diesel Exhaust Fluid is a stable, non-toxic, odorless and completely safe solution. The urea used for Diesel Exhaust Fluid is automotive-grade. Urea in additional forms is widely distributed for many other industrial and agricultural needs, including emissions control at public utilities and power plants.
