The Sierra 18-0129 Reed Block Gasket is a precision-cut replacement gasket designed to seal the reed block assembly in two-stroke marine and powersports engines. This gasket creates a critical seal between the reed cage and the intake manifold, preventing air leaks that can cause loss of performance and poor throttle response.

Key Features:

• Precise die-cut design ensures proper fit and alignment
• Durable material resists fuel, oil, and temperature extremes
• Replaces original equipment gasket for routine maintenance and rebuilds
