Claim Text:
1. A system comprising: an internal combustion engine operable to produce an exhaust stream; an exhaust aftertreatment system connected to said engine, the exhaust gas passing through the exhaust aftertreatment system; a reductant system connected to said exhaust aftertreatment system, the reductant system including a reductant dosing module with an inlet, said reductant dosing module including a chamber downstream of the inlet; a fluid connector connected to said reductant dosing module; and a reductant feed line connected to said fluid connector, said fluid connector includes a body made from a first material, said body defining a body cross-section, said body extending between and connecting said reductant feed line to said inlet of said reductant dosing module, the fluid connector including a first end and a second end opposite the first end, the first end coupled to the feed line, a first flange defined on the first end, the first flange abutting an end of the feed line, the second end coupled to the inlet of the reductant dosing module, a central hub positioned downstream of the first flange and defining a central hub cross-section larger than the body cross-section, a second flange continuous with the central hub and abutting a facing end of the inlet of the reductant dosing module, the second flange defining a second flange cross-section larger than each of a first flange cross-section of the first flange, the body cross-section and the central hub-cross-section, said fluid connector further including an insert made from a second material, the insert providing greater heat conductivity than said first material, said insert extending outwardly from said body and into said chamber to provide heat to reductant in said chamber from heat of reductant in said feed line.
