Description With the Paddle Board Valve Adapter inSPORTline , you don’t need a special pump to inflate your SUP, and can use a regular pump with a Schrader head instead. Compatible with inSPORTline paddle boards , this adapter allows you to use a hand pump , an electric pump and even an air compressor to inflate your SUP. As inflating with an air compressor can take longer, we recommend you start with a hand pump, and then use the adapter and air compressor for final inflation. With this practical Paddle Board Valve Adapter inSPORTline , you can inflate your paddle board quickly and with minimum effort, using a pump you already own. Technical description: Valve adapter for a hand pump, an electric pump and an air compressor Suitable for pumps with Schrader valves Suitable for paddle boards with HR (Halkey-Roberts) valves Dimensions: 8 x 3.5 cm
