Graco Mark HD for Intumescent FireProofing Sprayers

OEM Graco Mark HD Electric Airless — Intumescent Fireproofing Powerhouse

High-solids intumescent coatings don’t forgive weak pumps.Graco Mark HD Series was engineered to atomize viscous, fiber-filled fireproofing at 3,300 psi through tips up to .041 in, delivering a glass-smooth film build in a single pass. Yet even a beast needs fresh consumables. Our curated catalog of graco parts keeps every Mark V HD, VII HD, and X HD rig spraying profitably—no “close-enough” knock-offs. Graco Mark HD Electric Airless Sprayers are ideal for contractors who need versatility, reliability and performance. The Mark HD Series delivers time after time and gives contractors the flexibility to accomplish fireproofing and other jobs with the same sprayer.

Why Choose Genuine Graco Mark HD Parts Over Imitations?

• Exact-Fit Machining — Piston & packings held to ±0.002 in so SmartControl™ never hunts for pressure.
• MaxFlo™ Filter Stack — Triple-stage strainers rated for 100-KU slurries—aftermarket baskets collapse at half the load. 
• Vortex Chromex™ Rod — Rotates 360° each stroke, doubling packing life versus straight-plated steel.
• Drivetrain Warranty — Only OEM gears qualify, protecting the investment you charge for in every bid.
• BlueLink™ Connectivity — Log gallons, hours, and locations from your phone—vital when overseeing multiple sites.

Five Ways Genuine Parts Slash Field Costs

1. Zero Re-work Finish.  Machine-cut RAC X LP tips stay sharp 60 % longer, laying intumescent smooth and sagg-free.

2. Lower Pressure. Tight packings let you dial back to 2,400 psi, cutting overspray and solvent flash—less masking time.

3. Five-Minute Pump Swaps. QuikPak™ lowers change in five minutes with one wrench—priceless on a swing-stage at midnight.

4. Real-Time Diagnostics. BlueLink™ alerts flag suction leaks before they score the piston, saving a $500 rebuild.

5. Documented Compliance. Graco’s factory data sheets simplify FM-approved intumescent submissions.

Pro Tips for Multi-Season Reliability

Log every flush. Add the gallons to BlueLink™; schedule seal kits every 500,000 cycles.
Heat helps. Flush with 100 °F water—melts latex skin 4× faster than cold.
Color-code bins. Separate graco 360 paint sprayer parts from Mark HD components—one swapped O-ring can idle a $9 K pump.
Keep a spare. A backup pump lower costs less than two hours of crew downtime.
Reference the sheet. Mount the graco x7 airless paint sprayer manual and graco spray gun parts diagram at the wash-down station—one missing gasket can blow tonight’s bid.
