Exhaust manifold gaskets create a gas-tight seal between the exhaust manifold and cylinder head, preventing exhaust gas leakage. These gaskets are critical components in internal combustion engines, positioned between high-temperature exhaust ports and coolant passages. Construction typically utilizes layered steel, graphite, or composite materials for thermal stability and sealing force. Variations include embossed or coated designs to enhance conformability and resist exhaust gas corrosion. Proper installation and torque are essential to maintain sealing and prevent manifold warpage or fastener failure.
