Use this ceramic plunger on General Pump and Interpump brand pumps.

A cracked or broken ceramic piston can allow water into the pump crankcase, reducing lubrication and possible pump damage. A broken ceramic plunger can also sometimes be seen by a slight water leak between the pump body and pump manifold. Failure to replace a broken ceramic piston can result in further damage to pump, pump seals, unloader valves, and other pressure washer parts.
