Key benefit: Converts a standard air pump to fit paddle board, inflatable boat and kayak valves so you can inflate quickly without buying a special pump. Saves time and effort when preparing watercraft. Durable materials: Brass/copper metal body combined with rubber sealing components provides a solid structure and long service life. Manufactured under strict quality control to ensure consistent performance. Reliable seal and leakproof performance: Designed for good airtightness and strong sealing at the valve connection, reducing air loss during inflation and helping maintain pressure after use. Easy to use: Simple attachment converts conventional hand/foot/electric pumps to the required valve type in seconds. Laborsaving and practical for onsite inflation. Compatibility: Intended for most paddle boards, inflatable boats, kayaks and other common inflatables that use the same valve style. Works as an accessory for conventional air pumps to broaden their use. Typical applications: Beach paddle boarding: Quickly adapt a standard pump to inflate a paddle board before launch. Lake or river boating: Inflate or off an inflatable boat or kayak at the shoreline or dock without changing pumps. Rafting or field repairs: Use as a portable adapter to reinflate rafts and small inflatables during trips on streams or lakes. Performance highlights: Solid construction and rubber seals deliver dependable inflation and retention of air pressure. Practical for repeated use in outdoor conditions. What it solves: Eliminates the need for a dedicated pump for each valve type, prevents air leaks during inflation, and provides a compact, reliable adapter to keep your inflatables ready for use.
