Installation & Maintenance Tips

When installing the 127480 kit, follow these best practices:

Depressurize the system before disassembly.
Refer to the Graco service manual for torque specs and lubrication points. :contentReference[oaicite:3]{index=3}
Clean all mating surfaces carefully — any debris or dirt can reduce seal life.
After installation, run the pump at low pressure to “seat” the new piston before full operation.
Regular maintenance (e.g., lubrication, inspection) will extend the life of repaired components.

Why Use the 127480 Kit?

Using a factory-repair kit like the 127480 ensures that worn piston parts are replaced with high-quality, precisely engineered components. This not only helps restore your sprayer’s performance but also reduces the risk of future failure. Because these are genuine OEM parts, they maintain the correct tolerances and materials used by Graco in its original pump assembly.

Frequently Asked Questions

The kit includes a **piston** designed for the Graco 127418 pump and the required seals or rings. It does *not* include other components like valves, unloader, or rod — those must be sourced separately if needed.

Replacement intervals depend on usage, fluid type, and maintenance. However, if you start seeing leakage, loss of pressure, or uneven operation, it's a strong sign the piston or its seals are worn and may benefit from the 127480 kit.

No — the 127480 Piston Repair Kit is specifically for Graco’s **127418** pump, which is used in certain G-Force II direct-drive models. Using it in unapproved pumps may result in poor fit or failure.

While the 127480 covers the piston, other components like valves, unloader, or oil seals may require separate repair kits. To fully rebuild a pump, check your pump’s service manual for the correct part numbers. :contentReference[oaicite:4]{index=4}
