Get the Right Graco 490 XT Lo‑Boy Pump Assembly (19D873) Electric Airless Sprayer Parts Breakdown Components for Peak Performance

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.


Why OEM Matters: The Value of Genuine Graco 490 XT Parts

1. Precision Engineering for Consistent Fit & Output

OEM components are crafted within exact tolerances. That means you’ll maintain steady pressure, a stable spray pattern, and reliable performance—every time.

2. Chemical & Pressure Compatibility

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.

3. Warranty Integrity & Expert Guidance

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.


Comprehensive Breakdown of 490 XT Pump Assembly (19D873)

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:

• Pump Assembly / Housing

Central to fluid movement, featuring precision-fit housings, mounting hardware, and robust construction to handle thick materials.

Piston Rod Kit

Hardened, coated piston rods engineered to resist wear, along with sleeves and bearings.

• Packing & Seal Kits

Complete kits featuring Bytek™ V-rings, O-rings, fan packings, and all necessary hardware for a leak-free assembly.

• Inlet Suction Assembly

Includes hoses, clamps, quick couplers, and suction filters designed to stand up to harsh jobsite environments.

• Prime/SPGM-Valve

Switches your pump between spray and prime, precision-crafted to minimize internal leakage.

• Check Ball Kit

Includes seats and balls—ensuring efficient material movement and backup flow control.

• Filters & Strainers

Manifold, suction, and inline filters to protect sensitive parts from premature wear.

• Motor Brushes & Electrical Bits

Ensures your electric motor performs dependably under load, with replacement brushes, control boards, and plugs.

• Fluid End Hardware Kits

Clamps, seals, retainer plates—making it easy to rebuild without missing small parts.

• Spray Gun and Tip Components

Cross-compatible with RAC X tips, Magnum X7 guns, and robust guards for edge protection.
