Patented carbon-fiber heating provides design flexibility and allows faster thaw times with reduced power consumption Over-molded ends encapsulate electrical connections and provide weatherproof performance Temperature range: -40 Deg. F to +257 Deg. F (-40 Deg. C to +135 Deg. C) SAE J2044 quick-connect couplings Designed to match OE performance

Gates SCR Assemblies are specially designed and manufactured to convey Diesel Emission Fluid (DEF). Because DEF freezes at +11 Deg. F (-12 Deg. C), 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 Assemblies use Diesel Emissions Fluid (DEF) as a means of converting NOx in engine exhausts into harmless diatomic nitrogen gas and water.
