Abstract

The invention relates to an SCR line for treatment of exhaust from an internal combustion engine and including a first hose to carry a reducing agent, a second hose to carry a tempering agent and a pipe enclosing the two hoses. The two hoses are arranged in the pipe so as to run side by side in parallel. Each of the same-side ends of the first hose and of the pipe are connected to a reducing agent coupling housing. The ends of the second hose are each connected to a tempering agent coupling part separate from the reducing agent coupling housing. At least one of the reducing agent coupling housings has a through-opening at the outer perimeter. The second hose runs from the interior of the pipe through the through-opening to the outside. Furthermore, the invention relates to an SCR line bundle with an SCR line.
