ABSTRACT:
Disclosed herewith is a ball bladder orifice formed by a ball bladder orifice saddle, an orifice set, an inset tube and a strength washer. Since the saddle is welded to the bladder on the inside of the bladder, it will much more firmly adhere to each other than the conventional ones, wherein the saddle is attached to the bladder from the outside of the bladder. There is a hook at the bottom end of the orifice set. The hook possesses two functions: one is to hold all of the pieces stably and firmly; and, the other is to give more strength to seal the tube fissure at the lower end of the inset tube to keep the air from leaking as more air is pumped into the ball.
