Inflation Bag Adapter
Upgrade your inflation bag with the new style valve adapter that threads on to the outer male threads of the 2017 and later one-way valves. The new valve adapter is easier to keep in place (no more having the adapter disconnect if you accidentally back-twist the bag during inflation) and allows you to keep the valve in closed position during inflation. With practice, you can inflate to nearly boatable pressure with just the inflation bag. The inflation bag can also be turned inside out and used with 2016 and earlier threaded dump valves.
