Graco 105280 Packing O-Ring

The Graco 105280 Packing O-Ring forms a sealed connection between internal equipment components to support containing fluid air, or pressure during operation. It works by compressing between mating surfaces and fitting into designated grooves where it reduces leakage around moving or stationary parts within the system. This is commonly installed inside pumps, spray equipment, or fluid handling assemblies near seals, valves, or piston components. The part is used in repair and maintenance applications involving worn or damaged sealing elements. It supports standard operations associated with fluid control and pressure management in compatible equipment systems.
