Why Choose Genuine Graco 390 PC Cordless Airless Sprayer Stand Pump (17C487) Parts?

The Graco 390 PC Cordless (17C487) is one of the most trusted cordless sprayers in the industry—renowned for portability, durability, and consistent atomization. But the pump is its heart—and worn-out or aftermarket components can quickly derail even the best rig.

✔ Built to Exact Tolerances

Genuine parts ensure perfect fit, fluid integrity, and operational efficiency. Whether it’s a pressure control knob, piston rod, inlet valve, or full pump replacement, OEM tolerances keep your sprayer spraying like new.

✔ Tested for Chemical & Pressure Compatibility

All parts meet strict Graco standards for use with high-pressure, solvent-based, and water-based coatings. Substandard materials can deform, corrode, or fail under load—OEM replacements don’t cut corners.

✔ Supported by Warranties & Technical Expertise

All products come backed by Graco’s manufacturer warranty and our own technical team’s jobsite-tested experience. When you're on deadline, that peace of mind is priceless.

Pro Tips for Long-Term Equipment Performance

Want to reduce your repair budget and increase sprayer uptime? Integrate these proven maintenance strategies:

Track Service Intervals

A simple logbook or digital app helps you preempt wear failures. Key intervals include pump seals (every 400 gallons), inlet strainers (every 100 hours), and fluid section rebuilds (seasonally or as needed).

Re-Lube with Every Seal Kit

Graco’s TSL™ (Throat Seal Liquid) extends the life of your piston and packing by reducing heat and wear. Don’t reuse old lubricant when replacing seals—it’s a small step that makes a big difference.

Keep a Backup Pump Handy

Store an assembled 17C487 Stand Pump or displacement assembly on the truck to slash downtime during multi-day jobs or remote site work. That’s money in your pocket every time you avoid a service delay.

Color-Code Your Parts Bins

Avoid misplacing critical parts like Graco nozzles and tips or Graco paint sprayer parts diagrams by organizing your kits with color-coded labels—especially important when managing multiple crews or rigs.
