The Graco 803502 Piston is a precision ceramic plunger used in Graco high-pressure pump systems to generate consistent fluid pressure and reliable pump performance.
The Graco 803502 Piston is used inside specific Graco pressure washer pump assemblies. It is commonly installed in systems using the Graco 803508 pump.
The Graco 803502 Piston is a high-precision ceramic plunger piston designed for use in industrial high-pressure pumps. It moves inside the pump cylinder to generate the pressure required for efficient fluid delivery in professional pressure washer systems.
Manufactured for durability and performance, this piston works together with the pump seals, packings, and connecting rod to create the pumping action that produces consistent high-pressure output. Its ceramic construction provides excellent wear resistance and helps extend the service life of the pump.

Inside the pump assembly, the Graco 803502 Piston moves back and forth within the cylinder. This motion is driven by the pump crankshaft and connecting rod. As the piston travels forward and backward, it compresses fluid inside the pump chamber and pushes it out at high pressure.
This pumping cycle allows the pressure washer system to deliver strong and consistent spray performance required for industrial and professional cleaning applications.
