The genuine Pumptec "Kit B" valve and seal rebuild kit for Pumptec plunger pumps with M-style valves, with Viton seals. The valves open and close with every plunger stroke to move liquid through the pump. When debris fouls them, or they wear out, the pump loses prime, loses pressure, or delivers uneven flow. Viton seals hold up to pest control chemicals, herbicides and solvents better than Buna.

M valves or U valves?
It depends on your pump. This M-valve kit fits the 112, 113, 212, 217, 348 and 356. The 114T uses U valves, so it needs the 10020 kit instead.
How do I know the valves are bad?
Common signs are a pump that won't prime, pressure that drops or pulses, or reduced flow at the gun. Debris is the most common cause, so keep a clean strainer on the pump inlet.
Should I replace the plungers and seals too?
For a complete rebuild, yes. Kit A replaces the plungers and seals. Use the 10005 for the 112T, or the 10013 for the 348U. Together, Kit A and Kit B restore the pump's wear parts.
