20562X254 Black Cap Filter Piston Assembly
Used on some older Water Soft Filters. If your piston has a black cap like the one shown in the picture, this is the piston that you need.
If your piston has an Orange Cap, you need the 20922C203
If your piston has a White Cap, you need the 20561X254
Note: We recommend installing a new seal & spacer kit anytime a piston is being replaced.
