Wanted to be able to use a bike pump with a hose extension to replenish air in the packraft when it starts to cool down on the water. This was made with measurements from the MRS Barracuda R2 Pro and may not fit other brands as they tend to deviate from each other. Used the top valve housing of the Prema TR618A tractor valve, with the internal valve removed.
