Chad's Tips - Why the Graco PC Gun Is a Game Changer for Paint Professionals

Written by Chad Robinson, Service & Hire Manager at SprayPlant

If you're spraying all day, you know the importance of a reliable, comfortable, and easy-to-maintain spray gun. Graco's PC Gun, part of its ProConnect™ system, was designed with productivity and comfort in mind. From tool-free rebuilds to reduced operator fatigue, it's a smart investment for any pro. Here’s why.

1. Revolutionary Cartridge System: Easy, Efficient, Smart

One of the standout features of the Graco PC Gun is its all-in-one plastic cartridge. This cartridge includes the needle, seals, springs, side-seals, and o-rings - 13 small parts in total - packaged into a single unit that can be replaced in seconds.

Benefits of the Cartridge System:

• Tool-free swaps: Just pull out the old cartridge and snap in a new one, no tools, no downtime!
• Consistent performance: Each cartridge guarantees a perfect rebuild, eliminating common assembly errors.
• Simplified troubleshooting: Diagnose issues like spitting by quickly swapping in a fresh cartridge. One small Caveat is that the guns are prone to clog more easily because parts are not made from higher quality metal. However, plugging in a new cartridge will solve any issues quickly and easily.
• Training made easy: Fewer internal parts mean less to learn and a lower chance of mistakes by new users.

Recycling: As for disposal, Graco hasn’t confirmed whether the cartridges are recyclable. They contain mixed materials and internal rubber seals, so recycling depends on local regulations. Always check with your local recycling centre, or Graco themselves.

2. Trigger Flexibility: Comfort for Every Hand

Graco clearly had user fatigue in mind when designing the PC Gun’s trigger system.

Here’s what makes it stand out:

• Adjustable trigger size: Switch between 2, 3, or 4-finger configurations to match your grip and spray style.
• Lighter trigger pull: Up to 50% less effort than traditional guns, helping reduce strain on your hand and wrist when you have a big spray job to complete.
• Real-world approval: Painters report significant reductions in fatigue during extended use.

Whether you're tackling large surfaces or doing detailed work, the customizable trigger helps you stay in control without wearing out.

3. Lower Inventory and Maintenance Overhead

Because the cartridge replaces 13 separate parts, you no longer need to stock needles, springs, or seals individually. That means:

• Fewer SKUs to manage.
• Less storage space needed.
• Lower risk of part mismatch or rebuild errors.

Plus, the internal components, especially in newer PC Compact models use Chromex-coated needles and stainless end caps, making them far more durable than older aluminium parts.

4. Ergonomics and Fatigue Reduction

Spraying for hours takes a toll. That’s why the PC Gun is built to minimize strain:

• Lighter design: The Contractor PC Compact weighs just 21oz, around 25% lighter than older guns.
• Balanced feel: Improved weight distribution makes for smoother motion and less hand tension.
• Customizable grip: With adjustable triggers and slimmer designs, operators can fine-tune for their comfort.

5. Improved Spray Quality and Reduced Clogging

Thanks to RAC X™ tip guards and integrated 60‑mesh filters, the PC Gun delivers:

• More stable spray patterns.
• Quick tip reversal to clear blockages on the go. With RAC X tips, you can twist (reverse) the tip 180 degrees, pull the trigger to blow out the blockage, then twist it back to normal spraying position, all without disassembling anything. This allows you to clear clogs quickly, mid-job, without stopping to clean the tip manually.

All of this results in a better finish quality and fewer interruptions. Please make sure you only use materials which are suited for spraying with this gun.

Additional Tips and Considerations:

• Daily lubrication: Use Graco Fusion grease and Quick-Shot grease to maintain o-rings and smooth performance.
• Watch for spitting: With thicker paints, ensure proper thinning or filtering to avoid performance issues.
• Handle with care: Some users mention the plastic handle may crack if dropped—so avoid impacts or consider protective casing.
