North America’s leading diesel exhaust fluid brand, UltraPure DEF, improves fuel economy while preserving air quality. It’s the premier choice for trucks, buses and diesel-powered cars because of its innovative formula that converts toxic NO2 emissions into water-vapor emissions. At Keller-Heartt, we’re proud to carry such a cutting-edge brand that lessens environmental impact while providing the same high standard you expect from DEF.


UltraPure DEF works incredibly well in engines that use selective catalytic reduction. SCR and DEF combined can improve fuel economy by up to 5 percent, making it the ideal fluid for your system. It’s extremely pure, with a 32.5 +/- 0.7 percent urea concentration. Completely formaldehyde-free and extremely low in heavy metals, this pure diesel exhaust fluid is essential for clean operation.

Because DEF is required for emissions after-treatment, and has been since 2010, this pure fluid is ideal for single vehicles, multiple trucks or entire fleets of diesels. UltraPure diesel exhaust fluid is available in cases of two 2.5-gallon jugs, 55-gallon drums and 330-gallon totes. We’re also proud to offer free shipping within Chicago.

At Keller-Heartt, we specialize in bringing you the best products from the world’s most renowned manufacturers. Products like UltraPure diesel exhaust fluid are products we can really stand behind, because they’ve been proven time and again. Whether you need to get a case of two 2.5-gallon jugs for personal use, a 55-gallon drum for your shop, or a 330-gallon tote of UltraPure DEF for an entire fleet of delivery trucks, Keller-Heartt has you covered. Because we sell them at near-wholesale prices, you can get everything you need without paying extreme markup like you would elsewhere.

UltraPure DEF fluid achieves two important goals for the lubricants and absorbents (link) industry: improving fuel economy and preserving air quality. This #1 DEF fluid reduces your vehicle’s emissions and the special urea solution actually converts dangerous NO2 emissions into more environmentally-friendly water vapor emissions. Even better, the SCR combined with the DEF in the UltraPure formula is expected to improved fuel economy 5% more than competitors.

For shops or retailers needing big, bulk supplies of diesel exhaust fluid, we stock nearly wholesale priced diesel exhaust fluid drums – just $180. That ends up costing just over $3 a gallon for high quality DEF!


On top of fluids for diesel engines, we also carry a huge array of other automotive lubricants to service your vehicle. From bulk brake cleaners to Shell antifreeze, we’ve got everything you need to keep your vehicle at its peak performance.
