This Inflatable Boat SUP Pump Adaptor allows you to easily convert your ordinary inflation tube to the paddle without the need for a special air pump. Made from high-quality copper and rubber, it ensures a solid structure, strong seal, and anti-leakage performance. With its easy-to-use design, simply insert the Schrader valve fitting and rotate to lock in place. Connect a standard electric pump for quick and effortless inflation. The adaptor is compatible with a wide range of paddle boards, canoes, rubber boats, assault boats, flushing pools, floating rows, inflatable beds, and kayaks. Efficiency is key with this air valve adapter. Use your car or bike tire inflator to easily reach the recommended PSI within 5-10 minutes. The larger the inflation pump or compressor you use, the faster the inflation process becomes. It is recommended to inflate the board by hand until it becomes difficult to pump, and then use the adaptor to top off the pressure. This ensures optimal inflation and performance.
