The NRS Super Pump Adapter Set comes with the Super Pump and Super 2 Pump. It's also a great combination of pieces that combine to let you connect to several common boat valves.If you have inflatables with several different types of valves, this Adapter Set can cure some of your inflation headaches!
The "bell-shaped" piece screws onto a Leafield C7 & D7 Valve Adapter, that is included in the Set. Then, the other Set pieces attach to it.
By mixing and matching the various parts, including the red and black O-ring spacers, you can attach your pump to Leafield C7 and D7 Valves, Halkey-Roberts New Short and Old Short Valves, Summit 2 Valves, H3 Valves and the Boston Valves used on earlier NRS Wild River Tubes.
There's also an attachment that fits the "pinch" valves on some air mattresses and pool toys.
And it's possible you may be able to attach to some other valves, by using your ingenuity and MacGyver skills; this is the valve adapter erector set!
