DEF Transfer Hose – Hand Built

Applications

Diesel Exhaust Fluid (DEF: aqueous 32.5% nitrogen solution of high-purity urea in de-ionized 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 DEF Transfer Hose 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 transferring and reeling applications. Static wire available for installation in Class I, Division 1 areas.
