20x4.0 fat tire tube replacement inner tube. Please confirm the inner tube size to ensure proper replacement.
The inner tube is made of high-quality rubber to ensure efficient performance and maximum shock absorption. An ideal choice for professional and industrial/commercial applications.
The thickened design prevents air from seeping into the inner tube, ensuring longer-lasting inflation while providing better puncture and leak protection.
Rubber-coated valve stem enhances the seal of the valve seat, preventing dust and sand from entering the inner tube and tire interior. The durable rubber valve seat design resists tearing.
