In the high-paced world of professional spraying, equipment reliability spells the difference between finishing on schedule and facing costly delays. The Graco 490 XT Lo‑Boy Pump Assembly (19D873) stands as a resilient, well-designed cornerstone of many spray rigs—but even this workhorse needs the right parts to maximize uptime and longevity. At Sprayersandparts.com, we’ve built a reputation as the factory-authorized supplier of genuine Graco parts, offering everything from major pump units to fine valves, filters, and rebuild kits—complete with the expert insight to keep you spraying at full capacity.
OEM components are crafted within exact tolerances. That means you’ll maintain steady pressure, a stable spray pattern, and reliable performance—every time.
Graco tests each part under rigorous conditions: high-viscosity coatings, solvents, high temperatures, and extreme pressures. Counterfeit or aftermarket parts frequently fail these criteria—leading to costly downtime.
Using genuine parts protects your warranty, and our technical team—drawn from seasoned field operators—offers installation advice, torque specs, and troubleshooting to back you up at every step.
The 490 XT Lo‑Boy pump assembly isn’t just one piece—it comprises a number of interworking parts that each need to be maintained. At Sprayersandparts.com, we break it all down for you:
Central to fluid movement, featuring precision-fit housings, mounting hardware, and robust construction to handle thick materials.
Hardened, coated piston rods engineered to resist wear, along with sleeves and bearings.
Complete kits featuring Bytek™ V-rings, O-rings, fan packings, and all necessary hardware for a leak-free assembly.
Includes hoses, clamps, quick couplers, and suction filters designed to stand up to harsh jobsite environments.
Switches your pump between spray and prime, precision-crafted to minimize internal leakage.
Includes seats and balls—ensuring efficient material movement and backup flow control.
Manifold, suction, and inline filters to protect sensitive parts from premature wear.
Ensures your electric motor performs dependably under load, with replacement brushes, control boards, and plugs.
Clamps, seals, retainer plates—making it easy to rebuild without missing small parts.
Cross-compatible with RAC X tips, Magnum X7 guns, and robust guards for edge protection.
