Seal O-Ring for Foot Valve – Product Overview
The Graco 504817 Seal O-Ring Foot Valve is a genuine replacement sealing component designed for use inside Graco foot (intake) valve assemblies. This seal plays a critical role in maintaining proper pump prime by preventing material from flowing backward through the intake valve during operation.
Installed at the fluid intake section of the pump, this O-ring helps ensure consistent suction, smooth material flow, and reliable pump performance. Worn or damaged foot valve seals can cause pressure loss, poor priming, and uneven spraying, making timely replacement essential.
