Graco 116308 External Retaining Ring

Graco 116308 External Retaining Ring

The Graco 116308 External Retaining Ring is an OEM-grade snap-ring / circlip designed to fit around a shaft or external surface to hold internal components — such as bearings, sleeves, seals or rotating parts — securely in place. It prevents unwanted axial movement or disassembly under pressure, vibration, or load. :contentReference[oaicite:4]{index=4}

Compatible Assemblies & Use Cases

• Graco spray, pump or fluid-handling equipment assemblies that include external snap-rings in their parts breakdown (part # 116308). :contentReference[oaicite:5]{index=5}
• Any mechanical assembly within Graco machines — shafts, couplings, housings or swivel joints — where an external retaining ring is required to lock components axially and maintain alignment under operational stresses. :contentReference[oaicite:6]{index=6}

Product Features & Benefits

• External ring design: snaps onto shaft or external groove to retain components part-axially, preventing sliding or disassembly under load or vibration. :contentReference[oaicite:7]{index=7}
• OEM-spec part: ensures correct size, fit and material quality as per Graco original design — important for safety and reliability. :contentReference[oaicite:8]{index=8}
• Maintains mechanical integrity: by holding bearings, spacers or seals firmly in place, reduces wear, misalignment risk, leakage or mechanical failure due to part movement. :contentReference[oaicite:9]{index=9}

When & Why to Use / Replace

• Use during assembly or re-assembly when original retaining ring is missing, worn, damaged or lost — ensures correct axial retention and safe operation.
• Replace if ring shows deformation, wear or loss of tension — a weak or damaged ring may fail to hold parts, leading to dangerous disassembly under pressure, leaks or mechanical damage.
• Important for maintenance of pumps, guns, couplings or any shaft assemblies — correct retaining ring helps preserve longevity and safe functioning of Graco equipment.
