The Oxygen Tank Holder accessory from Pride allows you to ride with your oxygen tank for ultimate convenience. This oxygen tank holder is designed to fit both D and E size tanks. For the smaller D tank, there is an adjustment on the holder that allows the smaller tank to fit securely in the holder. As this accessory attaches to the universal rear hitch adapter, it is compatible on almost every Pride scooter, including the Victory, Maxima, Revo, Go-Go, and Celebrity Series's, as well as the Travel Pro.
