Abstract:
A gasket for an exhaust system, comprising:a plate having an exhaust sealing segment and a coolant sealing segment attached to and extending from the exhaust sealing segment, said exhaust sealing segment and said coolant sealing segment each having first and second planar surfaces on opposite sides thereof, said first and second planar surfaces of said exhaust sealing segment being coplanar with said first and second planar surface of said coolant sealing segment, respectively; an exhaust opening formed through the thickness of said exhaust sealing segment, said exhaust opening being shaped to be alignable with an exhaust passage of the exhaust system; a first elastomeric seal disposed on said first surface of said coolant sealing segment; a second elastomeric seal disposed on said second surface of said coolant sealing segment, said first and second elastomeric seals being integral parts of a common elastomeric element; a raised portion of said exhaust opening extending at an angle from said exhaust sealing segment away from said first surface to form a transition segment from a first opening of a first size which is coplanar with said first surface to a second opening of a second size which is displaced from said first surface, said raised portion being sized to be inserted into said exhaust passage, and a coolant hole through said plate located at said coolant sealing segment, said coolant hole being aligned with a coolant passage of said exhaust system.
