Probably suitable for some models, but I couldn't get it to work with Expedit's integrated pump. I made a better fitting adapter from a piece of garden hose.

Exped pad pumps (Schnozzel Pumpbag, Pillow Pump, Mini Pump) are solid performers. So much so it’s not a bad idea to use them with other pad brands as well.
This adapter enables use with external valves with a diameter between16 and 25 mm. A flat valve can needs to be between 14 - 16 or 20 - 22 mm. If the adapter doesn’t fit, Exped recommends the use of self-amalgamating tape to enlarge the diameter.
