Graco 116166 Carbide Ball Check Valve

Graco 116166 Carbide Ball Check Valve

The Graco 116166 Carbide Ball Check Valve — listed as “BALL, CARBIDE” by Graco — is a genuine OEM check‑valve ball used in valve assemblies for fluid/pump systems. The carbide construction ensures high wear resistance and reliable one‑way flow control, preventing reverse flow or back‑pressure that can damage pump or fluid circuits. :contentReference[oaicite:4]{index=4}

Compatible Systems / Applications

• Graco hydraulic / pump / fluid‑handling systems using check‑valves that require a carbide ball — whenever part # 116166 is specified. :contentReference[oaicite:5]{index=5}
• Industrial spray, coating, or fluid‑transfer equipment where durability and resistance to wear/abrasion is needed — especially with abrasive coatings, solvents or heavy‑duty fluids. :contentReference[oaicite:6]{index=6}

Product Features

• Genuine Graco OEM‑ball — exact spec for check‑valve assemblies requiring 116166. :contentReference[oaicite:7]{index=7}
• Carbide material — provides high wear & abrasion resistance, enhancing valve lifespan under harsh / abrasive fluid applications. :contentReference[oaicite:8]{index=8}
• Compact ball design — suitable for check‑valves with tight internal tolerances; ensures reliable sealing and flow control. :contentReference[oaicite:9]{index=9}

When & Why to Use / Replace

• Use when original check‑valve ball is worn, leaking, or damaged — replacing with the genuine carbide ball helps restore proper one‑way flow and prevents leaks/backflow.
• Recommended for systems handling abrasive or heavy fluids (paint, coatings, resins) where generic valve balls may wear quickly — carbide gives better longevity.
