O-Ring 2.175 x .103
The O-Ring 2.175 x .103 is a precision sealing component designed for compatible Mercury outboard applications. It helps create a secure seal between mating components, preventing fluids from escaping and supporting reliable operation of the engine assembly.
O-rings are small but important components used throughout marine engines and mechanical systems. They are designed to seal connections where fluids or pressure need to be contained. Over time, exposure to heat, pressure, vibration, engine fluids, and demanding marine conditions can cause a seal to become worn or deteriorated.
Replacing a damaged or worn O-ring can help restore the integrity of the connection and reduce the risk of leaks. With a specified size of 2.175 x .103, this component is intended for applications requiring these particular dimensions. Correct sizing is essential to ensure the seal sits correctly within the mating components.
The O-Ring 2.175 x .103 is a practical replacement for boat owners, marine mechanics, and technicians carrying out Mercury outboard maintenance, servicing, or repairs. It can be used during component replacement or engine reassembly where the original seal requires replacement.

Before ordering, always check your Mercury outboard’s model, serial number, and original part number to confirm compatibility. O-rings can look similar while having different dimensions and applications, so matching the correct specification is important.
For best results, the sealing surface should be clean and free from damage before installation. The O-ring should also be correctly positioned without twisting, stretching, or damaging the seal during installation.
Whether you’re completing routine maintenance or repairing a Mercury outboard engine, using the correct O-Ring 2.175 x .103 can help maintain a secure seal and reliable operation.
