Head Gasket - Sierra Marine Engine Parts - 18-0491 (118-0491)

The head gasket provides a leakproof seal to the cylinders. It ensures maximum compression and prevents coolant and engine oil from leaking into the cylinders. If the gasket loses its seal because of the cylinder heads' gradual warping and pitting, causing harsh engine operation and loss of power due to deteriorating compression seals. The HEAD GASKET 18-0491 accommodates the surface finish requirements for each application. The perfect sealing solution to seal imperfect surfaces and rigorously tested on an actual operation to ensure optimal performance.
