Key benefits Protects your craft’s inflation valve from water, dust and debris so seals stay clean and reliable. Simple valve plug that prevents air loss and helps maintain proper inflation between uses. Lightweight, flexible rubber construction provides long service life without adding bulk or weight. Compatible with a wide range of watercraft valves so you can use the same plug across boards, boats and kayaks. What it does Functions as an air valve plug to seal inflation valves on rubber boats, kayaks, surfboards, inflatable boats, paddle boards and similar watercraft. Waterproof and dustproof design blocks moisture and particles from entering the valve, reducing corrosion and wear. Durable rubber material resists cracking and deformation from repeated use and exposure to sun and water. Key attributes Material: Flexible, durable rubber for a tight, forgiving seal and long-term performance. Function: Valve plug — seals inflation valves to prevent leaks and contamination. Compatibility: Designed for use with valves on rubber boats, kayaks, surfboards, inflatable boats, paddle boards and other watercraft. Performance: Easy to install and remove by hand; maintains a reliable seal under normal recreational use. Use scenarios Pre-launch protection: Insert the plug after inflating a stand-up paddle board to keep the valve clean and secure while on the water. Storage and transport: Use the plug before packing or storing an inflatable boat or kayak to keep dust and moisture out of the valve and extend valve life. On-the-water replacement: Swap in the plug if an original cap is lost or damaged during a surf or day-trip to quickly restore a secure seal. Why customers choose this plug Solves common problems: prevents water and dust ingress, reduces the risk of slow leaks, and protects valve components from premature wear. Practical and reliable: simple design that does the job without adding weight or complexity. Note: Intended as a valve sealing plug for common watercraft inflation valves; confirm fit with your specific valve type if exact size match is required.
