Modular duct connection and seal

A duct system for an air intake system for a vehicle, the duct system comprising:

• a first duct including a first duct wall that defines a first duct opening and forms a conduit configured for conveying fluid through the first duct opening in an axial direction of the first duct opening, at least one contact surface provided on opposite sides of the first duct wall located across the first duct opening in a lateral direction of the first duct opening perpendicular to the axial direction of the first duct opening;
• and
• a second duct including a second duct wall that defines a second duct opening in fluid communication with the first duct opening, and forms a conduit configured for conveying fluid through the second duct opening,
• wherein the at least one contact surface is positioned such that when the second duct is installed on the first duct along the lateral direction of the first duct opening, the at least one contact surface engages with and seals against the second duct wall at the opposite sides of the first duct wall located across the first duct opening in the lateral direction of the first duct opening.

A duct system for an air intake system for a vehicle, the duct system comprising:

• a first duct including a first duct wall that forms a rim defining a first duct opening, and forms a conduit configured for conveying fluid through the first duct opening in an axial direction of the first duct opening, wherein at least one contact surface is provided on opposite sides of the first duct wall located across the first duct opening in a lateral direction of the first duct opening perpendicular to the axial direction of the first duct opening;
• and
• a second duct including a second duct wall that defines a second duct opening in fluid communication with the first duct opening, and forms a conduit configured for conveying fluid through the second duct opening,
• wherein the rim at the at least one contact surface extends in the axial direction of the first duct opening from the first duct toward the second duct such that when the second duct is installed on the first duct along the lateral direction of the first duct opening, the at least one contact surface engages with and seals against the second duct wall.
