Sierra Marine O-Ring

Sierra Marine O-Rings are replacement o-ring seals made for marine engines, outdrives, and related boat hardware. An o-ring is a round-section sealing ring. It sits in a groove and is compressed between mating surfaces to keep fluids, oil, water, or fuel from leaking past a joint or fitting.

Key Features:

• Round cross-section design that gives a reliable compression seal in static sealing applications
• Made for the demands of marine service, including exposure to moisture, fuel, and lubricants
• Sold under the Sierra International brand, a well-known supplier of marine engine parts, drive components, and service items
• Available in multiple inside diameter and width options so you can match the size your application calls for

Replacing worn, hardened, or flattened o-rings during service helps prevent leaks and protects your engine and drive components. Choose the variant that matches your required inside diameter and width.
