GRACO 288897 - Gun Rebuild Kit w/ Stainless Steel Trigger for Finex Side Cup & Pressure Feed Guns (0.031"–0.098" Nozzle)

Restore like-new trigger feel, shutoff, and air valve performance on your Finex spray gun with the genuine GRACO 288897 Gun Rebuild Kit. This kit is designed to refresh the common wear points inside Finex side cup and pressure feed guns—helping prevent air leaks, inconsistent triggering, and poor fluid control that can show up after heavy use or aggressive solvents. A stainless steel trigger is included for improved durability in demanding shop environments.

Fits These Finex Gun Styles

• Finex Side Cup guns (HVLP or Conventional)
• Finex Pressure Feed guns (HVLP or Conventional)
• Compatible with Finex setups using 0.031" to 0.098" needle/nozzle sizes (range varies by gun style)

What’s Included

• Stainless steel trigger (included with the kit)
• Trigger wear parts (trigger pin/retainers and trigger-related service parts)
• Air valve service parts (seat/valve/spring and sealing components)
• Fluid needle sealing components (packings, packing nut, and related seals)
• O-rings and internal seals used throughout the gun body
• Adjustment and guide components commonly replaced during a rebuild
• Additional included items may apply to specific Finex configurations (gravity vs pressure feed)

Why Replace the Rebuild Kit

• Helps correct air leaks at the trigger/air valve and inconsistent on/off
• Improves trigger response and repeatable spray control
• Replaces seals and wear components that can swell, harden, or cut from solvents
• Extends gun life without replacing the entire spray gun

Specs

Notes

• This kit rebuilds the gun’s internal wear components; it does not replace the needle/nozzle/air cap set. If your spray pattern is worn or the nozzle is damaged, you may also need the correct needle/nozzle/air cap kit for your size.
• Confirm your Finex gun style (side cup vs pressure feed; HVLP vs conventional) to ensure you’re pairing the correct needle/nozzle size with your setup.
