An O-Ring increases clamping pressure around the combustion chamber. O-RING, CYL HD (5/PK) 335523-PK is designed to strengthen the cylinder sealing in high-cylinder-pressure operations. The pieces of metal encircle the bore and chamber, augmenting the head gasket sealing capabilities. An O-ring is a gasket with a circular-looped design to seal two working surfaces. Without this small and otherwise simple component, the oil may leak into the valve guides where it?s burned inside the combustion chamber. This is specifically for cylinder head O-Ring for 18-7110 335523 0335523 Evinrude Johnson 90-175HP.
