The General Pump 44040266 is a 13mm ceramic piston (plunger) for General Pump EZ Series 44 triplex plunger pumps. The polished ceramic surface resists abrasion and heat for long seal life, and replacing a worn or cracked plunger keeps water out of the crankcase so the pump stays properly lubricated.
