Sierra Marine O-Ring

Sierra Marine O-Rings are replacement marine O-rings (also called O-ring seals or rubber sealing rings) for outboard and sterndrive engines and lower units. They are designed to seal joints, fittings and housings against water and fluid leaks in demanding marine conditions.

Key Features:

• Aftermarket replacements engineered to match the fit and function of the original OMC/Evinrude/Johnson parts they replace
• Elastomer construction made for the fuel, oil, lubricant and water exposure common in marine use
• Flexible sealing that conforms to mating surfaces to help prevent leaks
• Supplied from Sierra, a well-known supplier of marine engine parts and accessories

Replacing worn, hardened or cracked O-rings during service helps keep seals reliable and protects internal components. Check each individual listing for the specific part number, size and OEM cross-reference.
