Graco XT Mark IV Pro Hi-Boy Sprayer

Graco XT Mark IV Pro delivers contractor-grade muscle without the bulk of a gas rig. Powered by a 2.9 HP brushless Xtreme-Torque motor and an Endurance Vortex MAXLIFE pump, it moves up to 4.5 L min^-1 (1.2 gpm) through .031-in tips at 3 300 psi. That throughput turns blank walls into revenue fast right up until a 60-mesh filter plugs or a Chromex rod starts weeping. Seasoned contractors turn to SprayersAndParts.com for factory-serialized graco paint sprayer parts that bolt in, prime up, and get teams back on the gun. Our live exploded diagrams drill from the SmartControl 4.0 board down to the PTFE back-up ring.

Why Choose Genuine Graco XT Mark IV Pro Hi-Boy Parts?

Chromex rods = 2× life. A nickel-diffusion chrome layer resists silica fillers far longer than flash-chrome clones keeping volumetric efficiency ≥ 90 % past 1 000 hours.
SmartControl ±1 % accuracy. Boards ship pre-flashed for the Mark IV’s torque curve; knock-off boards hunt, surge, and waste paint.
3 300 psi burst margin. OEM manifold blocks, RAC X guards, and graco hose assemblies are hydro-tested to 4 950 psi critical during tip-clean spikes.
Plug-and-Spray warranty. Stay genuine to keep Graco’s Lifetime Advantage Drive coverage and warranty intact.
QR micro-guides. Every kit includes a scannable 90-second video correct torque & Loctite spec right on your phone 30 ft up a lift.

Cross-Fleet Compatibility One Bin Rescues Many Rigs

Graco builds on modular DNA; stocking Mark IV parts keeps a mixed fleet productive:

GMAX 7900 Gas. Same RAC X guard, tip seats & inlet strainer ideal when pairing electric for interiors and gas for rooftops.
Magnum Project Painter Plus 257025. Tip guard and manifold filter match via adapter see Buy Graco Magnum Project Painter Plus 257025 Parts List.
Graco 395 Sprayer. Shares filter core, ball seats, and many O-rings great for trim crews who need graco 395 sprayer parts on-site.
TrueCoat 360 Handhelds. LP tips preserve fan geometry; stocking graco truecoat 360 parts & graco truecoat 360 replacement parts means touch-up matches wall finish.

Five Habits for 2 000-Hour Pumps

1 — Log gallons. Swap packings every 1 000 L latex / 500 L elastomeric.
2 — Flush warm. 40 °C water dissolves acrylic twice as fast; half-pressure back-flush protects the transducer.
3 — TSL every break. Two drops keep Chromex rods mirror-bright.
4 — Monthly torque. Crankcase bolts 20 N·m; loose bolts pulverize gears.
5 — Stock redundancy. One $70 filter + $220 pump kit beats a $5 000 delay.
