For contractors who demand power, precision, and uptime, the Graco 455 ST Pro Hi-Boy Airless Paint Sprayer delivers jobsite-ready performance every time. But even the most durable tools need care—and that’s where Sprayersandparts.com comes in. We make it easy for professionals to source and service their Graco systems with a full lineup of genuine parts and accessories, ready to ship and backed by expertise.

Whether you're handling daily maintenance or a full equipment rebuild, our parts store is your one-stop solution. From Graco drywall texture sprayers to Graco 455 ST Pro replacement parts, we provide everything you need to finish faster and minimize downtime.


Why Choose Genuine Graco 455 ST Pro Hi-Boy Airless Paint Sprayers?

Your equipment is an investment—and cutting corners with aftermarket or off-brand parts can cost you in the long run. When uptime and finish quality matter, choosing authentic Graco 455 ST Pro parts is the smartest move.

✅ Engineered for Maximum Uptime

Each part is built to precise OEM tolerances, ensuring seamless fit, consistent spray patterns, and dependable operation. From packings and valves to filters and tip guards, every Graco part is designed for compatibility with your 455 ST Pro Hi-Boy model.

✅ Proven Pressure Ratings and Chemical Resistance

All parts are tested to meet Graco's high-performance standards for pressure output and material compatibility. You can count on safe and reliable operation whether you’re spraying latex, primers, texture, or solvent-based finishes.

✅ Backed by Graco Warranty and Our Technical Support

Don’t gamble with generic. Every part from Sprayersandparts.com is Graco-authorized and warrantied, and our expert support team is on hand to offer real-time advice on install procedures, compatibility, and maintenance best practices.


Key Features & Specs: Get the Details Before You Buy

When it comes to sourcing airless sprayer parts, accuracy matters. That’s why every product listing on our site includes:

  • Detailed Measurements (length, thread type, and diameters)

  • Material Grade Information (stainless steel, tungsten carbide, nylon, and more)

  • Max Pressure Ratings (to match your pump’s PSI specs)

  • Interchange Compatibility (with related Graco units and legacy assemblies)

Need to match a legacy Graco 455 sprayer configuration or check if a part fits other units like the Graco TrueCoat 360 Electric TrueAirless Sprayer? We’ve done the research for you.


Same-Day Shipping & Professional-Grade Support

Time is money, especially on the jobsite. That’s why all orders confirmed by 12 PM Central qualify for same-day shipping from Graco warehouse (Terms & Conditions apply).

Pro Tips for Long-Term Reliability

Keeping your Graco 455 ST Pro Hi-Boy sprayer in top shape doesn’t require a lot of time—it just takes the right practices. Here are expert-backed recommendations to help you maximize equipment life:

Track Usage and Schedule Maintenance

Create a simple log of operating hours and coating types used. Replace packings, valves, filters, and seals on schedule—not after failure.

Always Lube New Seal Kits

Graco seal kits are designed for extended life, but they still require proper lubrication during installation. Use OEM-recommended lubricant to avoid dry starts and premature wear.

Stock Spare Components

When deadlines are tight, you don’t want to be caught without a critical part. Keep extras of common wear items like inlet strainers, piston rods, and prime valves in your jobsite kit or van.

Organize Parts for Quick Access

Set up color-coded bins or compartments for related components like Graco airless sprayer accessories, extension tools, and gun rebuild kits. This makes on-site maintenance or last-minute repairs faster and error-free.
