DEF Dispensing Hose
Product Specifications
Application
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.
Continental ContiTech is specifically 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 significantly 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.
