Head gaskets for the 6.7L Cummins Marine engine (2007.5–2018) seal the cylinder head to the engine block. They handle high compression and extreme heat in marine use. Made from multi-layer steel (MLS) or composite materials, these gaskets resist blowouts and keep a tight seal under high boost and pressure. They are precision-cut to fit factory specs and seal coolant and oil passages properly. Whether for maintenance, rebuilds, or upgrades, these gaskets provide reliable, long-lasting performance in marine conditions.
