    SCR Assemblies

    Gates Diesel Emission Fluid (DEF) Hose Assemblies are specially designed and manufactured to convey Diesel Emission Fluid (DEF). Because DEF freezes at -12°C (+11°F), the hose and couplings are electronically heated using our revolutionary carbon fiber heating system. This patent pending technology allows for more uniform fluid heating compared to heated-wire designs and features thermoplastic over-molds to protect electrical connections against moisture and corrosion. SCR uses Diesel Emissions Fluid (DEF) as a means of converting NOx in engine exhausts into harmless diatomic nitrogen gas and water.

    • Temperature Range: -40°C to +135°C (-40°F to +257°F).
    • Working pressure 14 bar (200 psi) maximum.
    • Patented carbon fiber heating provides design flexibility and allows faster thaw times with reduced power consumption.
    • Over-molded ends encapsulated electrical connections and provide weather proof performance.
    • SAE J2044 quick connect couplings.
    • Designed to match OE performance.
