Why You Need a Valve Hole Grommet

When an inner tube is removed, the valve hole in your rim is left exposed. Without a protective plug, the sharp rim edge can scratch valve stems during reinstallation, and dirt or moisture can enter the rim cavity. A quality rubber grommet plug protects both your rim and your new inner tube — extending the life of your components and making every tube swap cleaner and faster.
