OEM Parts for Graco 455 ST Pro Lo-Boy Airless Paint Sprayers, Get the Right Graco 455 ST Pro Lo-Boy Airless Paint Sprayers Components for Peak Performance
When Graco 455 ST Pro Lo-Boy airless paint sprayers keep your crew productive, downtime is money lost. Professional contractors rely on SprayersAndParts.com because every component—from graco 395 pc displacement rods to graco 360 paint sprayer parts kits—is factory-authorized, in stock, and ships. 455 ST shares the 3000 psi (210 bar) fluid section found in Graco’s entire ST Pro family, so many of the pumps, seats, and seals interchange with the 395 ST and 495 ST lines, simplifying on-site inventories.
Why Choose Genuine Graco 455 ST Pro Lo-Boy Airless Paint Sprayers?
- Exact engine-to-pump tolerances: the 242011 120 V motor couples to a hardened 243183 Endurance™ pump rated 0.48 gpm, delivering consistent atomization at tip sizes up to .021″.
- 3000 psi maximum working pressure verified in ISO-certified test cells—after-market clones rarely publish pressure curves.
- Backed by Graco Warranty.
Key Features & Specs
• Motor: Permanent-magnet DC, brush-replaceable (kit 243214).
• Flow: 0.48 gpm @ 3000 psi lets you spray interior latex, primers, and light elastomerics.
• Tip compatibility: .010″–.021″ RAC V or RAC X tips; swap to RAC X LP 517 to cut overspray by 55 %.
• Suction: flexible 195489 tube with 183770 rock-catcher strainer stops clogs before they reach the filter.
Cross-Compatibility With Other Graco Rigs
455 ST’s 243183 pump also fits the graco 395 PC and uses the same 187615 stainless valve seat as the graco 490 PC Pro parts crossover, allowing mixed fleets to run a single seal-and-seat kit. Stepping up? The 490 PC Pro pushes 0.54 gpm and supports .025″ tips while retaining the familiar one-minute swap pump you already know.
Must-Have Accessories & Texture Guns
- Graco TexSpray RTX Air-Spray Trigger Gun – filter-less, oversize passages for heavy knockdown mud. Matches RTX 750 through 1250.
- BlueMax™ II ¼″ x 50′ Hose – 10 % lighter than steel braid yet still rated 3300 psi.
- RAC X LP 517 & 531 Tips – spray at 500 psi lower pressure, saving paint and lungs.
- CleanShot™ Shut-Off Valve – eliminates “spit” when spraying cabinets or trim.
Pro Tips for Long-Term Reliability
Log strokes not days: the hour meter is good, but packings fail by stroke count—replace every 40 000 cycles to avoid cylinder scoring.
Top-off TSL daily: two drops of Throat-Seal Liquid in the wet-cup (part 206994) cuts friction and keeps paint out of the upper bearings.
Color-code bins: green for graco filters and strainers, red for graco airless spray guns, blue for graco texture sprayer guns—new hires grab the right part instantly.
Carry critical spares: a 243080 60-mesh manifold filter and 17P186 seat kit cost less than a gallon of finish but can save four hours of downtime on commercial rollouts.
