Replacement Plunger Assembly. Constructed from sapphire and has a diameter of 0.280 inches. The sapphire plunger, which moves with the piston, fits into the pump head and fills the pump head with solvent (through the inlet check valve) when it retracts. The plunger expels the solvent from the pump head when it extends forward. It is recommended to change seals when changing plungers. Used on 2525/2535/2545 Pumps.
