UltraPure Diesel Exhaust Fluid (DEF)

Diesel Exhaust Fluid (DEF) is a non-toxic, high purity solution comprised of 32.5% urea and 67.5% de-ionized water. Using this fluid in diesel-powered vehicles (such as trucks, buses, and tractors) helps to reduce the amount of nitrogen oxides (NOx) emitted into the air by 90%. DEF is not a fuel additive and must be filled into the dedicated Diesel Exhaust Fluid tank on your diesel vehicle.

We have been providing Diesel Exhaust Fluid (DEF) solutions to customers, distributors, and dealerships in the North American trucking market since 2009. With over 1,000,000 million gallons of bulk API certified Diesel Exhaust Fluid (DEF) storage across North America, we're ready to meet your needs!

API Logo


The American Petroleum Institute (API) is the only national trade organization that certifies the quality of DEF to international standards and licenses manufacturers who consistently meet these standards set by the International Organization for Standardization (ISO).

The API Diesel Exhaust Fluid Certification Program is a voluntary program designed to certify and monitor DEF quality. API issues a seal to those manufacturers who are committed to quality and meet specific performance requirements. UltraPure® DEF is certified by API and proudly displays their seal on our packaging.

What this means to our customers:

  • Provides rigorous monitoring of fluids in the marketplace
  • Identifies brands meeting diesel engine manufacturer requirements
  • Helps consumers easily recognize those brands

Diesel Exhaust Fluid Jugs

2.5 Gallon JUGS

A 2.5 Gallon Jug will provide enough fluid for up to 750 miles.

Jugs are equipped with a single-use, easy reach, flexible dispensing nozzle designed to fit DEF vehicle fill ports, and do not require any equipment.

55 Gallon DRUMS

A 55 Gallon Drum will provide enough fluid for up to 16,500 miles.

This size is ideal if you have one or two trucks and will last several months, depending on how many miles are driven. Drums should be stored indoors to prevent freezing in colder climates.

Diesel Exhaust Fluid Tote

330 Gallon TOTES

A 330 Gallon Tote will provide enough fluid for up to 99,000 miles.

We offer one-way returnable and refillable totes. Returnable DEF totes can be returned and refilled as long as there has been no contamination. Refillable on-site totes can be left at your location and will be refilled by a Brenntag delivery truck.


Mini-bulk quantities range from 330 gallons to 2,000 gallons and bulk quantities are considered anything over 5,000 gallons.

Bulk storage systems vary in size from 2,000 gallons and up. We will come directly to your facility to fill your mini-bulk and bulk storage system with a minimum delivery quantity of 250 gallons.
