This fitting is needed to fill and empty old water bed technology sacs using the Tsunami Pump

This Pro X Fat Sac Check Valve prevents spilling in between taking the pump off and putting the cap on, but it will take 5 minutes longer to fill and empty with it. Therefore we decided not to include it with the Pro X Fat Sacs because most people want to save the extra 5 minutes filling and the extra 5 minutes emptying. The way this Pro X Series Check Valve works is by incorporating a rubber flap that prevents water from spilling, but it is impossible to make any Check Valve that does not slow the flow of water when filling and emptying.

A turn of this air release plug will release unwanted air from your Fly High Pro X Series Fat Sacs.
