Tecumseh 35499 O-Ring Gasket Rubber

The Tecumseh 35499 O-Ring Gasket is a genuine OEM rubber seal that creates a reliable, leak-free barrier at engine-fluid junctions in Tecumseh small gasoline engines. Made from oil- and fuel-resistant rubber elastomer, it prevents oil or fuel from escaping while guarding against dirt and moisture intrusion. It is commonly installed on oil fill tubes, dipstick tubes, and other sealing points where fluid sealing is essential in outdoor power equipment, including lawn mowers, snow blowers, generators, tillers, and chipper shredders powered by Tecumseh engines. Maintained by repair and service teams, this part supports routine maintenance, engine rebuilds, or retrofits by replacing worn, cracked, or deteriorated O-rings. It is an OEM replacement part, and its compatibility spans Tecumseh and various brands—Toro, Craftsman, Cub Cadet, MTD, Troy-Bilt, Husqvarna, Lawn-Boy, and Simplicity depending on model. Common replacements include Tecumseh TC-35499, 36832 Quad Ring Seal, and 35577 Oil Fill Tube Seal, underscoring its role in oil-fill and dipstick sealing applications. The 35499 designation confirms its identity for these specific seal locations, enabling effective lubrication maintenance and fluid containment across multiple outdoor power equipment applications.
