DEF Fluid Hoses

Gates' Diesel Emission Fluid (DEF) Hose Assemblies are all designed and manufactured to convey diesel emission fluid. Gates' DEF hose assemblies are electronically heated using Gates's revolutionary carbon fiber heating system, providing faster thaw times, lower amp draw, and more uniform heating than OE heated-wire designs. A dense, closed-cell EPDM cover resists cuts and abrasion better than typical OE replacements for longer life in harsh environments.
