The Graco 220658 Kit Conversion (4:1) upgrades compatible pump systems to a 4:1 pressure ratio for improved spraying of medium- to high-viscosity coatings.
At this time, Graco has not published an official public list of exact machines for the Graco 220658 Kit Conversion (4:1). Compatibility depends on pump series, drive type, and internal configuration. Always verify using your sprayer’s model and manual before installation.
The Graco 220658 Kit Conversion (4:1) is a genuine Graco conversion kit engineered to modify an existing compatible pump system to operate at a 4:1 pressure ratio. This conversion allows the sprayer to generate four times the fluid pressure relative to the supplied air pressure, making it ideal for handling medium- to high-viscosity coatings.
This kit is commonly used in professional and industrial coating applications where improved material flow, consistent pressure, and better atomization are required. It helps upgrade an existing system without the need to replace the full pump assembly.
