The Graco 01/0084/98 Shaft Piston 1/2 SS is a genuine OEM stainless steel piston shaft engineered for high-pressure Graco pumping systems. It functions as a critical internal motion component that drives the piston assembly within industrial fluid handling and spray equipment. Manufactured from corrosion-resistant stainless steel, it is designed to ensure smooth reciprocating movement, stable pressure output, and long service life in demanding operating conditions.
This component is typically used in precision pumping systems where consistent fluid displacement is required, especially in applications involving coatings, sealants, and industrial chemicals. Its OEM-grade design ensures exact fitment and reliable performance within compatible Graco machinery systems.
The shaft piston transmits mechanical motion within the pump assembly, enabling controlled fluid compression and discharge. This ensures consistent spray patterns, stable output pressure, and reduced wear on surrounding pump components.
