Professional Pressure-Feed Finishing Gun - Overview & Key Details
Graco 289247 Finex Air Spray Pressure Feed Gun is a lightweight, ergonomic finishing gun designed for consistent atomization and an excellent surface finish. It ships configured with a 1.0 mm needle/nozzle set and optimized air cap for fine-finish work.
Compatible Machines / Systems
This model is a Pressure-Feed air spray gun. It connects to pressurized fluid supplies and shop air it does not use a gravity or suction cup. Pair it with the following:
- Pressure pots / pressure tanks (e.g., 2 qt, 2 gal, 10 gal) providing regulated fluid pressure to the gun.
- Pressure-feed pumps/packages (diaphragm or piston feed units) used in industrial/auto/wood finishing lines.
- Finishing systems with dedicated fluid regulators, fluid hoses and shop air.
Connections: Air inlet 1/4" NPSM | Fluid inlet 3/8" NPSM. Ensure your pot/pump and hoses match these sizes for a direct fit.
Why choose the Finex Pressure-Feed Gun
- Easy trigger pull and balanced body to reduce operator fatigue in long spray sessions.
- Optimized air cap and 1.0 mm setup for fine atomization on clears, stains and light-to-medium viscosity coatings.
- Durable build for shop use; simple needle/nozzle swaps for different materials.
- Works seamlessly with common pressure-feed pots and pump systems.

Frequently Asked Questions
Yes- if your system can supply regulated fluid pressure and shop air, and your hoses terminate to 3/8" NPSM (fluid) and 1/4"NPSM (air). Adapters can be used if your hose ends differ.
For many light waterborne finishes, the 1.0 mm works well. For heavier waterborne or high-solids materials, move up to a larger needle/nozzle and fine-tune air/fluid pressures from your pot or pump.
No. This is a Finex Air Spray gun for pressure-feed systems. It is not designed for airless or AAA tip setups.
Use a compatible air hose to 1/4" NPSM and a fluid hose to 3/8" NPSM. Many pressure pots ship with these standards; otherwise, choose hoses/adapters to match your tank or pump outlets.
