The Tecumseh 34951 Washer Cup is a precision rubber component designed to maintain proper fluid and air control. This washer cup fits within pump or carburetor assemblies where it flexes under pressure to create a tight seal against mating surfaces. As pressure changes, the cup expands and contracts to prevent leakage and support smooth operation. Its durable construction resists wear, deformation, and common contaminants found. By helping maintain correct pressure and reducing fluid loss, the washer cup supports efficient operation, minimizes downtime, and contributes to longer service of related components. It is suitable for routine maintenance or direct replacement during repairs. Keep your tools organized and ready with a reliable toolbox and the Tecumseh Washer Cup for your next project. #Tecumseh #TecumsehParts #34951 #WasherCup #LawnMowerParts #PowerToolsParts #powertools #HomeImprovement
