B Cartridge Valve 15918 for Meyer E-58H WILL NOT FIT E-47, E-57, and E-60 Plow Pumps. This is also the C & D Cartridge Valve for E-68 / 88. Scroll through ALL of the images for clarification. Might be clamshell packed, might be a zip lock bag. We have a few dozen new PA Blocks with all the Valves in them we disassembled for individual parts sales.
