Professional Overview - Graco 289241 Finex Air Spray Gravity Feed Gun
Graco 289241 is an HVLP, gravity-feed finishing gun with a 1.8 mm (0.071 in) nozzle. Designed for clean atomization and reduced overspray, it’s ideal for primers, enamels, sealers, and medium-to-higher viscosity coatings where a smooth, controlled finish is required.
Compatible Machines / Systems
Place this gun at the heart of your finishing setup. It “fits” (connects to and works with) the following:
- Air compressors with clean, dry air and a 1/4" NPSM air inlet line (typical shop/regulator setups).
- HVLP spray booths and finishing stations using standard air regulators and filters.
- Gravity cups for Finex/Graco gravity guns (mounted on the gun; no remote pump required).
- Optional remote supply (pressure pot / fluid line) using a 3/8-18 NPSM fluid connection (if adapted for pressure feed).
- Finex family accessories such as air caps, needle/nozzle kits, and typical HVLP air hoses/regulators.
Key Features
- HVLP gravity-feed design for efficient material use and lower overspray.
- 1.8 mm nozzle size suited for primers, sealers, and medium-body coatings.
- Ergonomic, well-balanced body with light trigger pull for reduced fatigue.
- Durable wetted parts (aluminum, stainless steel, engineered plastics).
- Easy maintenance with readily available Finex repair parts and kits.

Frequently Asked Questions
Yes. The 289241 is an HVLP gravity-feed model designed to reduce overspray and improve transfer efficiency compared to conventional air spray.
The factory setup is 1.8 mm (0.071 in), great for primers, sealers, and medium-body coatings. For thinner topcoats, consider a smaller orifice in the Finex family.
It connects to standard shop air compressors via a 1/4" NPSM air inlet and uses a gravity cup. You can optionally adapt to a remote pressure pot/fluid line using a 3/8-18 NPSM fluid connection.
Maximum air inlet is 100 psi (≈ 7 bar) and maximum fluid pressure is 100 psi (≈ 7 bar). Always spray within the coating and booth guidelines.
Flush after each use with a compatible solvent, keep air passages clean and dry, and periodically inspect the needle, nozzle, and air cap. Replace worn parts with genuine Finex/Graco kits.
