Graco 116550 Retaining Ring

Product Description

The GRACO 116550 is a retaining ring designed to secure internal components within Graco-manufactured spray and fluid-handling equipment. Retaining rings of this type provide a mechanical stop that prevents axial movement of shafts, pins, or other rotating parts inside pumps, spray guns, and related assemblies. This part is typically installed or replaced by contractors, industrial maintenance technicians, and equipment service professionals working on Graco-branded spray finishing or fluid transfer systems.

The 116550 retaining ring is suited for repair and maintenance applications where internal components need to be held in position within a housing or bore. It is commonly used as a direct service replacement when the original ring shows signs of wear, deformation, or damage during disassembly. Service intervals often require inspection of retaining rings any time a pump or spray gun assembly is opened for internal maintenance.

Key Features

• Maintains axial positioning of internal components within Graco fluid-handling assemblies
• Designed as a direct OEM-style replacement part for Graco equipment
• Compact form factor suited for installation in tight internal bores or around shafts

Installation Notes

Retaining ring installation and removal should be performed by a qualified technician using the appropriate internal or external retaining ring pliers to avoid ring distortion or personal injury. Depressurize and power down all equipment completely before beginning any disassembly. Follow Graco service documentation for the specific assembly to confirm correct ring orientation and seating position. Inspect the groove and mating surfaces for wear or debris before installing the replacement ring.
