Purity of diesel exhaust fluid is important to maintaining a functioning SCR system. Any chemical impurity in DEF can lead to failure of an SCR system. That is why it is very important to use only DEF products that meet ISO 22241-1 standards. Blue Sky DEF 32.5 is a stable, colorless, nonflammable, nontoxic fluid. Blue Sky DEF 32.5 conforms to the ISO-22241-1 specification for DEF, is API registered and meets or exceeds OEM specifications. We ensure a quality product with an extensive, redundant quality management process, controlling specifications through the entire product channel—from manufacturing through distribution to the end user.
