A single pinhole leak or worn needle can halt that fireproofing schedule cold. Smart contractors rely on SprayersAndParts.com for factory-serialized graco parts that swap in minutes, preserve warranty, and get revenue flowing again.

Stay Job-Ready with Long-Life Graco DutyMax DH230 HD Spray Gun & Hose Components

Our most-ordered kit pairs a Contractor PC airless gun and a BlueMax II 3/8 in × 50 ft hose (240797) rated at 3300 psi and 180 °F. The whip-ready hose core resists solvent swell, while the gun’s modular cartridge swaps a worn needle in 60 seconds no bench vice, no special tools.

Five Reasons Pros Buy Genuine

• True 3300 psi burst margin. Each BlueMax II hose is hydro-tested to 5000 psi (150 % of working pressure) before it leaves the factory.
• Viton + PTFE seals. Contractor PC gun seals shrug off hot solvent blends that shred nitrile knock-offs.
• 50 % lighter trigger pull. The gun’s SmartTrigger spring cuts fatigue on all-day roof jobs game-changer when running a graco drywall skimming blade in the other hand.
• Color-match rebuild cartridges. Swap a red (.017) or blue (.021) seat in under a minute.
• Full Graco warranty.

Key Specs at a Glance

One Kit Many Compatible Rigs

Because Graco standardizes threads and pressure ratings, this gun-and-hose combo drops into a surprising number of sprayers, slashing inventory clutter:

• DutyMax GH230 / EH230 / DH300—identical 3/8 in outlet, 3300 psi system.
• GMax II 7900 gas frame—swap directly for texture or block-filler days.
• Ultra Max II 795 / 695 ( 2.2 hp electric )—same BlueMax hose rating and Contractor PC seats.
• LineLazer 3400 stripers—filter, seat and swivel all match graco 495 paint sprayer family rigs.
• Magnum X7 & Project Painter Plus—use RAC X tip guard; see graco magnum project painter plus parts diagram for thread adapter 17M223.

Smart Add-Ons for a Bullet-Proof Fluid Path

1. BlueMax II 3 ft Whip (25C827). A 1/8-in micro-hose at the gun cuts wrist torque and dampens pressure spikes ideal for overhead work.
2. RAC X LP & FFLP Tips. Twelve low-pressure patterns slash overspray 50 % and extend hose life by reducing amp-draw-induced surges.
3. Quick-Flush Valve. Plug in a garden hose, back-flushing the pump and hose in 60 sec perfect when spec calls for a graco extension tools boom.
4. Ground Strap Kit. Stops static arcs when spraying silica-filled elastomerics or heavy iron-oxide primers.
5. Contractor PC Repair Cartridge (17Y297). Keep one in the gang box; swap an entire needle, spring & seat mid-shift no bench vise.

Field-Proven Maintenance Blueprint

1 — Log Hose Hours. Swap at 500 gal latex or 250 gal roof mastic.
2 — Flush Warm. 40 °C water dissolves acrylic twice as fast; half-pressure back-flush keeps grit from the transducer.
3 — Lube the Rod. Two drops TSL every coffee break keeps seats mirror-bright.
4 — Re-Torque Weekly. Gun handle 17 N·m; swivel 20 N·m.
5 — Stock Redundancy. One $70 hose + $200 gun kit saves a $5 000 shift carry two per crew.
