Cross-Model Compatibility That Shrinks Your Parts Wall
You don’t park just one sprayer on the trailer, so we’ve built a catalog that links the 595 to the rest of your fleet:
- Graco 395 PC: Shares the same SmartControl pressure sensor and many fluid-section O-rings —ideal for touch-up rigs when 595 is pushing primer.
- Graco TrueCoat 360 accessories: RAC X tips, FlexLiner bags, and 20 in extensions keep handheld units productive and fit directly on 595 guns for door jambs and cabinets.
- Graco 490 parts: ProConnect™ pumps slide into 595 frames in a pinch, and packings interchange so one service kit covers two sprayers.
- Graco 7900: Filters, tip guards, and BlueMax II hoses are cross-platform, letting you bulk-buy consumables and score volume discounts.
Pro Tips to Triple Pump Life
- Clock your gallons: The 595’s digital display tracks pump hours—log them and swap packings every 500 gal to avoid midnight blowouts.
- Always use a Graco spray guard: The RAC X HandTite guard handles up to 4 050 PSI, reduces paint build-up, and threads onto any 7/8 G gun.
- Pump Armor nightly: Two-minute flush equals $0.40 in fluid—far cheaper than a $375 pump rod.
- Color-code consumables: Separate graco sprayers parts like filters and tip seals from graco paint sprayer attachments (extensions, roller kits)
Upgrade Path—Attachments
Boost versatility without buying another rig:
- Pressure Roller System: Snap a 40 in extension roller onto the 595 gun to back-roll decks four times faster than tray rolling.
- JetRoller® combo: Spray and back-roll in one pass—up to 4× faster.
- Tip Extensions & Pole Guns: Reach 12 ft ceilings without ladders—extensions up to 36 in available.
