Yamaha - Fuel Filter Cup O-Ring - 93210-37M25-00

Overview

The Yamaha 93210-37M25-00 Fuel Filter Cup O-Ring is a small but critical sealing component used in Yamaha outboard fuel filter assemblies. This O-ring creates a tight seal between the fuel filter cup and housing, preventing fuel leaks while ensuring proper fuel system pressure and filtration performance.

Over time, exposure to fuel, heat, and engine vibration can cause O-rings to harden, crack, or lose elasticity. Replacing worn seals during routine maintenance helps maintain a secure fuel filter seal and protects the engine’s fuel system from air leaks and contamination.

Designed to Yamaha OEM specifications, this fuel filter cup O-ring ensures proper fitment and reliable sealing across a wide range of Yamaha two-stroke outboard engines.
