Abstract: A heatable hose conduit system is provided for an arrangement for the aftertreatment of exhaust gas in an internal combustion engine. The arrangement introduces a liquid reduction agent into the exhaust gas of the engine. The heatable hose conduit system has hose conduits that conduct the liquid reduction agent and are arranged in pairs in close proximity to hose conduits that conduct heating water. At least one end of at least one pair of hose conduits (6, 7 or 8, 9) terminates at a common connecting block that has a plug member of a plug-and-socket connector. The liquid reduction agent is conducted via the connecting block into the interior of the unit (11) to be connected and the heating water is conducted through a throughflow channel (20) which has an outlet outside the unit (11).

Abstract: A heated urea conduit arrangement includes a hose conduit (3), which conducts an aqueous urea solution, and runs parallel to a hose conduit (4) carrying heating water. Both hose conduits (3, 4) are surrounded by another hose (5) that shrinks around them when heated.
