This carburetor gasket fits a Citroën SM carburetor. The gasket seals the contact surface between carburetor and intake manifold. It limits leakage of air and fuel and supports a stable mixture. The material resists fuel and engine temperatures and retains shape under mounting pressure. The dimensions follow the original specification for correct fit. The gasket supports idling, throttle response and general engine operation. Replace the gasket during carburetor removal or overhaul. Use of a new gasket keeps the joint between components closed and maintains carburetor function. This reduces the risk of unmetered air entering the intake path.
