Diesel Exhaust Fluid (DEF: aqueous 32.5% nitrogen solution of high-purity urea in deionized water) is a key
component of selective catalytic reduction (SCR) systems, which help diesel vehicles meet stringent emission
regulations effective January 1, 2010. DEF is a liquid reducing agent that reacts with engine exhaust in the
presence of a catalyst to convert smog-forming nitrogen oxides (NOx) into harmless nitrogen and water vapor.
Goodyear Engineered Products DEF Dispensing Hose is specifcally designed to convey the high-purity,
aqueous urea solution DEF. Hose tube compound is specially formulated with low extraction EPDM and
peroxide cured to provide superior extraction levels to signifcantly reduce contamination. Flexible softwall
construction provides superior handling in standard dispensing and reeling applications. Static wire available
for installation in Class I, Division 1 areas.
