Rubber sleeve for the connection between heater and bulkhead of a Citroën DS. The sleeve closes the opening in the bulkhead and limits the entry of water, dust and engine noise into the interior. The material is dimensionally stable rubber that withstands temperature changes in the engine bay. The fit is matched to the original heater pass through and supports correct routing of air and coolant lines. The sleeve contributes to the protection of cables and hoses around the heater unit and helps maintain a stable climate in the passenger compartment by sealing the heater bulkhead area.
