Blue DEF DEF330 Diesel Exhaust Fluid - 330-Gallon Tote contains Diesel Exhaust Fluid (DEF). One of the key elements of the Selective Catalytic Reduction (SCR) process used by most medium and Heavy-Duty engine builders to meet EPA 2010 regulations. Blue DEF is a Nontoxic Solution Of 67.5-Percent Purified Water And 32.5-Percent Ultra Pure Automotive Grade Urea. Blue DEF is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, Blue DEF helps convert NOx into Nitrogen Gas and Water Vapor – two harmless and natural components of the air we breathe.

Blue DEF is Stable, Colorless, and Odorless, and meets ISO Standards 22241 for purity and composition and is an American Petroleum Institute (API) certified diesel exhaust fluid. These are the highest quality and safety standards in place to ensure optimum SCR performance. Making sure you do not run out of Blue DEF in a SCR equipped truck is simple – watch the BlueDEF Gauge, which is part of the diesel fuel gauge, for when it is time to refill. Blue DEF is stored in a dedicated tank next to the fuel tank on the driver's side. The tanks range in size from 6 to 23-Gallons depending on the truck's application. The Blue DEF tank fill opening is designed to accommodate a Blue DEF Fill Nozzle to ensure only Blue DEF is put into the tank.

A Diesel Fuel Nozzle will not fit into the Blue DEF tank opening. Our patented Closed Liquid Dispensing System provides everything you need to effectively dispense your Blue DEF. In order for Blue DEF to be effective, product integrity is critical and Blue DEF Dispensing Systems are the only way to maintain this quality. These Blue DEF Reusable Systems are also cost effective by providing significant savings over single-use containers. Blue DEF Dispensing Systems are available in configurations for Fleet, Retail, and Commercial applications. Blue DEF is key to helping improve fuel economy by up to five Percent while simultaneously reducing exhaust emissions.
