Graco 106524 Packing O-Ring

The Graco 106524 Packing O-Ring operates as a sealing element that controls fluid containment within pump and hydraulic assemblies. It works by fitting into a machined groove where it compresses between mating surfaces, forming a circular seal that blocks leakage while allowing internal components to move during pressure cycles. This compression-based action supports controlled transfer within the system during operation. This is typically positioned inside pump housings, piston assemblies, or valve sections where shafts or plungers interact with sealed chambers. It is installed during maintenance or replacement of worn parts in compatible fluid equipment systems.
