4110-801 (FAM-PB3) - Filling Adaptor to fill Puritan Bennett from male CGA 540 - 3 length

If you have a bottle from Aircraft Spruce, or an Aerox bottle with a Schraeder-type filling valve (such as the PrO2 Plus), this is the filling adapter you need - it adapts the PB3 typle valve to a standard CGA540 hose for easy filling.
