0406R Replacement Flapper Valve for 1-Gal & 2-Gal Power Bleeder Pumps

The Motive Products 0406R is a direct-fit replacement flapper valve for the pump assembly used in Motive 1-gallon and 2-gallon Power Bleeder tanks. The flapper valve is the check valve that allows fluid to move on the down-stroke and seals on the up-stroke — a worn or torn flapper kills pumping efficiency and prevents building adequate pressure.
