Why Choose Genuine Graco 190 PC Hi‑Boy Sprayer Parts (1)?
Precision Manufacturing for Peak Productivity
Every OEM part is machined and molded to exact factory tolerances. When you replace components like a prime valve or packing kit, you're restoring your sprayer’s original performance—delivering smoother flow, consistent spray pressure, and longer service life. Off-brand alternatives lack this precision, leading to premature wear and downtime.
Verified for Chemical Compatibility & Pressure Load
The 190 PC Hi‑Boy is built to handle heavy-duty coatings—thick elastomerics, solvent-rich primers, and high-build textures. Genuine Graco parts are rigorously tested to withstand pressures of up to 3000+ PSI and resist chemical degradation. Copycats often falter under these extreme conditions, risking seal failure or corrosion.

Pro Maintenance Tips That Save Time & Money
Log Regular Service Intervals
Track wear items like packings, filters, and seals. Replacing these components before failure helps avoid sudden shut-downs—especially on multi-day projects.
Lubricate With Every Seal Kit Install
Always pair kits with Graco Throat Seal Liquid (TSL) or Pump Armor. This reduces friction on pistons and valves, doubling seal life.
Keep Critical Spares In-Stock
Downtime is a productivity killer. Stock essentials like control box modules, prime valves, inlet strainer assemblies, and set of spray tips so quick repairs don’t sideline your crew.
Color-Code Your Spare Bins
Organize by sprayer model: Hi‑Boy components in one bin, 395 & Magnum parts in others. It keeps things efficient and mistake-free during busy mornings.
Match Tips & Guards With Care
Change tips regularly (every 50 hours or when flow drops). Use HC-grade stainless or chrome tips. Our listings include PSI charts for each tip/guard combination to maintain ideal spray patterns.
