Graco GMAXII 5900 Series Gas Airless Sprayer Parts

Unlock Maximum Uptime with Quality Graco GMAXII 5900 Series Gas Airless Sprayer Parts Spares

Graco GMAXII 5900 airless sprayer is the contractor’s “Swiss-army” gas rig—pairing a dependable Honda GX200 with a 1.6 gpm Endurance™ pump that will shove a 0.043″ tip through high-solids elastomeric all day long. 3 300 psi on tap means exterior block walls, intumescent coatings and two-gun production are fair game. But one worn packing or torn suction tube can switch the meter from billable gallons to $0/hr idle crew. That’s why pro painters, fire-proofing outfits and DOT stripers trust SprayersAndParts.com for OEM-serialized parts that ship same day and arrive torque-sheet ready.

Why Genuine Graco Parts Are the Only Parts Worth Buying

1. Chromex® Rod & MaxLife™ Seats – 64 Rc nitrided steel shrugs off titanium-dioxide that shreds stainless copycats in a weekend.
2. V-Max Blue™ Packings – UHMW/leather stack self-lubricates from 40 °F dawn starts to 110 °F rooftops—zero weep-by, zero callbacks.
3. SmartControl™ 4.0 Board – Holds fan width ±1 %; clone boards “hunt” and blow 10 % of every bucket into overspray with graco gas airless sprayer.
4. Endurance™ Vortex Pump – Up to twice the life of standard lowers and swaps in 60 s via ProConnect 2—no vise, no downtime with airless sprayer accessories.
5. Warranty Intact – Graco honours engine / pump coverage only when every replacement carries a factory serial.

• Ultra Max II 1095 / 1595 – Endurance 287513 lower bolts right on when the big electric coughs.
• Graco TrueCoat 360 VSP – LP tips & guards ensure touch-up blends match the main rig.
• Graco Magnum Project Painter Plus & XR7 – share RAC X guards, suction strainers and tip cleaning needles.

Five Daily Habits for a 1 000-Hour 5900 Run

• Flush Warm @ 100 °F – latex breaks down 30 % faster; BlueMax liners safe to 160 °F.
• Add TSL Each Bucket – five wet-cup drops every fill keeps Chromex rods mirror-smooth.
• Re-torque Packings After First Hour – leather seats when hydrated; one snug lasts the season.
• Mesh-to-Tip Discipline – 30-mesh ≥ 0.029″, 60-mesh 0.017–0.027″, 100-mesh for cabinet enamel.
• Colour-Code Parts Bins – blue = electric rigs, red = gas, green = handheld; no midnight mix-ups.

Lower Pressure • Fewer VOCs • Happier Clients

RAC X LP tips at 1 600 psi vs 2 300 psi save 0.12 gal paint per 1 000 ft²—cutting VOCs 11 lb on a 200-gal project. Chromex rods outlive clones by two repacks, sparing 1.2 lb steel landfill each swap. Kraft cartons are 90 % recycled; boards are RoHS-compliant.
