Features This SUP Pump adapter is made of high quality copper and rubber materials, it is quite sturdy and durable. No need for paddle-specific air pump, the conversion head can connect the ordinary inflatable tube to the paddle. With the valve in the closed position, insert the Schrader valve fitting and rotate to lock in place. Remove the cap on the fitting, and connect a standard electric pump, bike pump or compressor and inflate to the recommended PSI. Recommended: Because the compressors/tire pumps take time to inflate, 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.
