A Guide to Graco Sprayer Parts and Spray Guns

Graco Sprayer Parts and Spray Guns: Your Complete Guide

If you own or service a Graco paint sprayer, knowing your Graco sprayer parts is the fastest way to keep jobs on schedule and finishes consistent. From routine wear items to upgrade accessories, every component affects spray quality, uptime, and total cost of ownership.

Why Knowing Your Parts Matters

Graco sprayers are popular with contractors and DIYers for their reliability. Like any pro tool, they need periodic service. Understanding the system pump, filters, hose, gun, and tip lets you swap the right piece at the right time, avoid downtime, and extend your machine’s life.

Core Airless Components You’ll Service Most

• Pump (piston/endurance): Pressurizes material and drives it through the hose to the gun. When performance drops, slow priming, pressure loss, inconsistent fan, plan a rebuild or swap with a kit matched to your model. For a broad, model-agnostic selection, see Graco pumps, pistons, cylinders & repair kits.
• Pressure control: Match output to coating and surface for uniform atomization.
• Manifold & gun filters: Keep debris out of the fluid path to prevent clogs and “tails.”
• High-pressure hose: Delivers consistent flow; inspect for wear, kinks, and fittings.
• Airless spray tips: Control fan width and orifice size. Use Graco’s Spray Tip Selector to size properly, and shop compatible Graco spray tips & guards.

Paint Spray Gun Parts & Accessories

The gun is the most handled component expect normal wear. Common service items include needles/seats, springs, trigger kits, seals, and gun filters; replacing these restores crisp patterns and smooth triggering. For comfort and control, add swivels, guards, extensions, and other accessories to reduce fatigue and improve reach. If you run a 490-class rig, keep model-specific spares handy see Ultra Max II 490 PC parts.

Pumps & Repair Kits

Because pumps do the heavy lifting, they’re serviced most. A typical kit includes packings, valves, O-rings, and lubricant so you can rebuild quickly and get back to work. If you’d rather swap whole assemblies or need pistons/cylinders and related pieces, browse pump repair components or the site-wide catalog of Graco painting & coating sprayer parts.

Choosing OEM vs Aftermarket

OEM parts ensure fit and performance; quality aftermarket can reduce costs on high-wear items. Whichever you choose, match the part number to your model and keep spares for the pieces you replace most (filters, tips, seals, gun kits). Using the correct components prevents overspray, clogging, and uneven finish.

How to Pick the Right Replacement

• Compatibility: Verify model and series for every order.
• Usage volume: High-output users may prefer heavy-duty kits and longer-life tips.
• Coating type: Thick elastomerics need larger orifices; thin stains need smaller tips and finer filtration.
• Maintenance cadence: Replace filters regularly, rotate spare tips, and keep a small seal/needle kit in the rig.

Quick Maintenance Playbook

1. Strain coatings and size your tip to the material; confirm your sprayer’s max tip rating (use the Tip Selector linked above).
2. Install fresh manifold and gun filters matched to the tip orifice.
3. Set pressure just high enough to remove tails; overlap passes ~50% at ~12″ distance.
4. Flush immediately after use; clean filters, tip, and guard.

Final Thoughts

With the right spares filters, tips, seals, and targeted gun or pump kits you can maintain performance, reduce downtime, and deliver a professional finish on every job. Keep a compact kit of essentials, lean on the resources above for part selection, and you’ll be ready for anything your next project throws at you.
