Graco 495st ProB Lo-Boy was engineered for crews that need pro-grade performance in a compact, low-profile chassis that slides under van shelving. Its 3000 psi (210 bar) pressure rating keeps atomization tight on interiors, while Lo-Boy 232944 frame centers the weight over rugged pneumatic tires for stair climbing without blow-outs. Contractors choose OEM parts because a single “close-enough” gasket can stall a five-person crew and burn profit by the hour.
Why Choose Genuine 495st ProB Lo-Boy Parts Over After-Market Copies?
- Factory CNC Tolerances ±0.002 in—SmartControl feedback never hunts, so your fan pattern stays razor-straight.
- Endurance Chromex Rod rotates a full 360° every cycle, doubling packing life versus straight-plate steel rods found in knock-offs.
- QuikPak Lower swaps in under five minutes—ideal when you’re on the clock for a hotel-turnaround.
- Gear-train Warranty—valid only when you run genuine Graco internals.
- ProConnect Pump Replacement means zero special tools on the jobsite: pull, snap, spray.

Drop-In Compatibility One Parts Bin, Many Rigs
Stocking 495st spares keeps more than one sprayer running. The displacement pump, filters and control boards also fit:
- Graco 490 PC Pro Lo-Boy & Hi-Boy (2014+ units share pump and control)
- Ultra Max II 495 PC Pro Lo-Boy (same 0.6 gpm pump)
- Ultra Max II 595 (2014 batch—identical packings and piston rod)
- Graco 650 Pro frame when converted with 17H200 manifold kit
- LineLazer 3400 stripe pump (uses the same 17C718 lower)
Five Tangible Ways OEM Parts Cut Costs
1. Fuel-Free Efficiency — Because the 495st is electric, a tight pump lowers amperage draw and keeps the generator on eco-throttle.
2. Longer Tip Life — Clean Easy-Out manifold filters stop grit that rounds graco nozzles and tips; lab panels show a 30 % extension in tip edge life.
3. Less Overspray — Steady pressure lets you back down to 2200 psi on finish coats, cutting masking time by half.
4. Five-Minute Pump Swaps — A spare QuikPak lower costs less than one hour of idle payroll; simply pull, pin, prime, and go.
5. Warranty Intact — The moment you drop a non-OEM seal into the mix, the lifetime drive guarantee disappears.

Field-Tested Tips for Multi-Season Reliability
Top up TSL daily. A dime of throat-seal lubricant each morning keeps packings slippery.
Rotate tip sizes. Start with .021 for primer, finish with .015 doubles tip life.
Flush warm. 45 °C water dissolves latex 3× faster than cold save solvent for oil jobs.
Color-code bins. Store graco paint sprayer parts separate from gun rebuild kits to avoid O-ring mix-ups.
Log gallons. Use a dry-erase tally on the frame or the BlueLink app; rebuild at 500 K cycles.
Keep a laminated graco pump parts diagram on the trailer wall for quick torque checks.
