Line section for the temperature-controlled guiding of a reductant for the exhaust gas aftertreatment of an internal combustion engine

A line section for temperature-controlled guiding of a reductant for the exhaust gas post-treatment of an internal combustion engine, the line section comprising:

• a first line for guiding the reductant,
• a second line for guiding a temperature control agent,
• a casing surrounding the first and second lines, wherein the first and second lines are disposed adjacent to each other in the casing and guided in a coupling housing, and the casing being connected to the coupling housing, wherein both the first and second lines are guided through the entire coupling housing extending adjacent to each other, and
• a first connector attached to an end of the first line and a second connector attached to an end of the second line, the first and second connectors being respectively attached to the first and second lines inside of the coupling housing in an outlet end region.
