ContiTech® DEF Dispensing Hose
ContiTech® DEF Dispensing Hose Diesel Exhaust Fluid (DEF: aqueous 32.5% nitrogen solution of highpurity 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 DEF Dispensing Hose is specifically designed to convey the highpurity, 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. Rated to temperatures of 140°F to 257°F (60°C to 125°C). Tube Specially formulated low-extraction EPDM, peroxide cured Cover Specially formulated low-extraction EPDM Reinforcement Polyester braid.
