Why Choose Genuine Graco Ultra 500 Parts Over Copycats?
- Exact-spec machining. Ultra 500’s pressure circuit is calibrated for 2 750 psi (195 bar); any deviation risks blowing seals or flashing error codes.
- Certified electrical safety. OEM boards carry UL listings and are matched to the sprayer’s ½ HP, 115 VAC DC motor for cool, consistent starts—even on 100 ft cords.
- Warranty intact backed by Graco.
Ultra 500 Punch-List Specs Contractors Care About
Ultra 500 is the “pickup truck” of Graco’s electric line—light enough for daily remodels, tough enough for commercial interiors:
- Motor: 0.5 HP DC, 2 700 RPM, 6.5 amps
- Max Working Pressure: 2 750 psi
- Cycles per Gallon: 470 (ideal for one-coat flat or low-VOC acrylics)
- Recommended Tip Range: 0.009-0.021 in for fine finish; 0.023-0.027 in for drywall primer
our control-box kit and your pressure stays rock-steady through the entire trigger pull—no sags, no streaks, no callbacks.
What’s Inside the Control Box Assembly?
Every kit ships shrink-wrapped and labeled for speed staging. Standard contents:
- Pre-calibrated pressure-control board (set to 2 750 psi stall)
- Factory toggle switch (
105679) and weatherproof boot (105659) - Switch guard (
107255) to stop accidental bumps in tight closets - Color-coded female/male insulated terminals for tool-free swaps—match the diagram, crimp, and spray
- Conduit connector and vibration grommet to keep drywall dust out of your electronics
The parts list mirrors Graco’s official service drawing—no mystery hardware, no missing screws.
Cross-Platform Compatibility Means Fewer SKUs on Your Shelves
You probably run more than one machine. Good news: many Ultra 500 electronics and fittings interchange with popular DIY and pro models, so you can slash inventory overhead:
- The Graco X7 and LTS 17 Diagram and Parts share the same ¼-turn pressure-sensor connector—keep one harness in the truck and repair any Magnum series pump mid-job.
- Order Graco Accessories like RAC X tip guards or BlueMax whips from the same cart—free shipping threshold hits faster and you only enter your card once.
- Need more flow for roof elastomerics? The Graco 7900 gas rig pushes 2.2 gpm at 3 300 psi—and its Graco tip guards, filters, and inline strainers drop straight onto Ultra 500 guns in a pinch.
Pro Tips to Stretch Control-Box Life 3×
- Log pump hours. A Sharpie on the skid plus a spreadsheet reminder keeps you swapping brushes every 400 hours—before arc flash cooks your board.
- Keep dust out. Add the optional gasketed motor cover if you spray attic knockdown; electronics hate gypsum.
- Use true ground. A 14-gauge, 3-wire cord and metal bucket grounding clip prevent static spikes that fry boards.
- Flush with Pump Armor. Two minutes at day’s end stops corrosion on terminals and pump rods alike.
- Color-code parts bins. Store Ultra 500 and graco machinery fasteners in separate totes so a missing lock-washer doesn’t derail tomorrow’s mobilization.
Frequently Asked Questions
Is calibration required after installing the board?
No factory board ships without a full 2 750 psi stall-pressure calibration. Just set max pressure once and you’re spraying in under five minutes.
Do I need special tools?
A #2 Phillips, a ¼-in nut driver, and a digital multimeter for continuity checks are all you need. Wire crimp sleeves are included in the kit.
Can I still find boards for legacy Series A rigs?
Yes—SprayersAndParts stocks new-old-stock boards for Series A and B Ultra 500 units.
