Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) is a non-toxic solution made of 32.5% urea and 67.5% deionized water, used in modern diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology. DEF helps reduce harmful nitrogen oxide (NOx) emissions by breaking them down into harmless nitrogen and water vapor. Maintaining proper DEF levels is essential—running out can cause significant engine power reduction (commonly known as “limp mode”) or even prevent the vehicle from starting. Most systems require regular refills to keep equipment operating efficiently and in compliance with emissions standards.

We offer DEF in convenient 55-gallon drums as well as bulk delivery options to keep your equipment running smoothly.
