32.5% DEF Solution (AUS 32)
AUS 32 is a diesel exhaust fluid solution that contains 32.5% urea and 67.5% deionized water. This is by far the most common type of diesel exhaust fluid as it used in many heavy-duty diesel trucks manufactured after 2010 and a number of other industrial applications. Azure DEF is your source for AUS 32 diesel exhaust fluid in Southern California.
To maintain your fleet or equipment, Azure DEF offers high-quality solutions that are made using an automated production process. Quality is always assured; we used high- quality, industrial-grade urea diluted in pure deionized water. By utilizing best practices and making product quality a priority, Azure DEF is the only diesel exhaust fluids supplier you will ever need. We can even monitor your DEFs to ensure you never run out.
40% DEF Solution (AUS 40)
Often referred to as “marine DEF,” AUS 40 is often used in high-combustion diesel engines, such as those used by water-based craft. Although, this higher concentration of urea (40%) and water (60%) is finding increasing use in many land- and locomotive-based applications.
Whether you are just looking for a small quantity of AUS 40 to be delivered to your facility, we can fulfill your request. We also offer free tank monitoring so you’ll never have to worry about running out of diesel exhaust fluids.
