Overview & Key Details
Graco 289258 Finex Air Spray Gravity Feed Gun is a compact, lightweight HVLP gun designed for precise, fine-finish work. It features a gravity cup, a 1.0 mm (0.039 in) nozzle set, and ergonomic controls to deliver a smooth finish on wood, metal, plastic, and composites with reduced overspray.
Compatible Machines / Systems
This manual spray gun is not tied to a single sprayer model. It connects to standard finishing setups that meet the air and fluid requirements below.
- Shop air compressors or plant air capable of supplying clean, dry air (regulated) to the gun’s 1/4" NPS(M) air inlet (up to ~100 psi max at inlet).
- Gravity-feed finishing setups using the supplied cup for small to medium jobs.
- Pressure-feed systems/pressure pots with proper regulation and a 3/8" NPS(M) fluid connection (via appropriate adapter if used as a pressure-assist setup).
- Booth-based finishing lines with inline air regulators/filters and quick-disconnects matching the gun’s inlet thread.
- Compatible with a wide range of coatings the Finex series supports: waterborne, solventborne, urethane, epoxy, sealers, and many high-solids materials (viscosity appropriate for a 1.0 mm tip).
Why Choose the Finex 289258
- Compact HVLP control for detailed parts, trim, cabinetry, and touch-ups.
- Ergonomic, lightweight design reduces fatigue in all-day use.
- Gravity cup minimizes material waste and speeds color changes.
- Fine 1.0 mm setup for smooth atomization on thin to medium-viscosity coatings.
- Durable build with easy-to-service needle/nozzle/aircap set.

Set-Up Tips
- Use a quality air filter/regulator; target low, consistent atomizing pressure for HVLP.
- Strain coatings; adjust viscosity for the 1.0 mm setup as needed.
- Start with fan/flow controls centered, then fine-tune pattern, material, and air.
- Maintain 6–8 in (150–200 mm) gun distance and keep passes parallel.
- Flush and clean immediately after use to protect seals and maintain pattern quality.
Frequently Asked Questions
No. The Finex 289258 is a manual HVLP air spray gun that connects to standard compressed-air finishing setups. Ensure your compressor and (if used) pressure pot meet the thread and pressure requirements listed above.
Thin to medium-viscosity materials such as waterborne lacquers, clear coats, urethane topcoats, and well-reduced epoxies. For heavier materials, consider thinning or a larger tip/needle set.
The gun uses a 1/4" NPS(M) air inlet. Match your quick-connect and hose to this thread and ensure clean, dry, regulated air to achieve consistent HVLP atomization.
Yes. While the 289258 is a gravity-feed gun, it can be used with a pressure pot/remote supply when correctly adapted to the 3/8" NPS(M) fluid path and regulated within the gun’s pressure limits.
Use properly filtered air, set HVLP pressures just high enough to fully atomize, adjust fan/material flow, maintain correct distance and speed, and keep the needle/nozzle/aircap clean.
