- Diesel exhaust fluid (DEF) – It is a very pure, aqueous, solution of urea which meets the automotive industry specification defined by ISO 22241. It’s a clear liquid similar in appearance to water. DEF is safe to handle and use – it is not explosive, flammable, toxic, or subject to any hazardous product regulations. The product can be purchased in a variety of packaging
