The Stardupp SUP valve 2022 is a replacement valve for the 2022 SUP boards from Stardupp.
Over time and everyday wear and tear, it is possible for a valve to leak. It is then very important to replace the valve since pressure loss from your board is at the expense of the SUP fun.
You can replace a valve by unscrewing the old valve with a SUP valve wrench. Then screw in the new valve.
As an extra security, a rubber ring can be placed between the valve and the SUP. See: STARDUPP RUBBER RING FOR VALVE/VALVE
