Explore Our Full Line of Professional-Grade Graco 495 ST Pro Lo-Boy (232941) Airless Paint Sprayers
Graco 495 ST Pro Lo-Boy marries big-job muscle with apartment-friendly portability. Its 1.2-hp brush-type motor drives an Endurance piston pump that outputs 0.60 GPM at up to 3300 psi enough to atomise high-solid acrylics through a 0.025 tip without thinning. Field crews love the low-slung chassis (under 36 lb) that rides beside the pail instead of over it, lowering the centre of gravity for stair climbs and van loading.
Why Choose Genuine Graco 495 ST Pro Parts Over Knock-Offs?
- Machined to ±2 µm—OEM Chromex rods keep packings alive twice as long as aftermarket steel.
- 3300 psi validation—each valve is burst-tested; many clones start weeping at 2500 psi.
- SmartControl handshake—factory sensors plug-and-spray; generics can trigger “pressure error” shutdowns mid-job.
- Full warranty —by Graco

Must-Have Graco Sprayer Accessories
Upgrading a 495 ST Pro Lo-Boy is the cheapest way to add speed and finish quality:
- Graco airless sprayer tips – step up to LP517-619 tips for 30 % lower overspray on interior latex.
- Graco paint sprayer attachments – a 20-inch Tip Extension keeps crews off ladders and OSHA inspectors happy.
- Graco texture sprayer guns – swap the Contractor PC nose for an RTX texture gun and atomise knock-down mud without changing rigs.
- Color-coded graco sprayer accessories bins – green for filters, blue for packings, red for gun kits zero mix-ups.
Pro Tips for Long-Term Reliability
Daily—Flush with FastFlush for 60 seconds; add five drops of TSL into the throat port. Cost: pennies. Payoff: packings that last a season.
Every 40 engine hours—log stroke count and inspect filter core; a clogged 60-mesh doubles pressure spikes and destroys rods.
Every 500 gallons—drop in a full packing kit (Rebuild 17C489), torque to 75 ft-lb, and purge with clean mineral spirits. A $130 kit beats a $700 pump rod.
