Yamaha - Float Chamber Gasket - Carburetor Sealing Component - 69M-14984-00-00

Overview

When a carburetor starts acting up, a worn gasket is often the quiet cause behind it. This gasket seals the float chamber so fuel stays where it should and the carb can meter it properly. Once it flattens out or loses flexibility, you’ll start seeing leaks or inconsistent performance. It’s a small part, but it’s one of the key pieces that keeps your engine running clean and steady.

Key Features

• Fuel Bowl Seal Integrity – Creates a tight seal between the float chamber and carburetor body.
• Leak Prevention Design – Helps stop fuel seepage and maintain safe operation.
• OEM Precision Fit – Built to Yamaha specifications for proper alignment and sealing.
• Fuel-Resistant Material – Designed to handle constant exposure to fuel and engine heat.
