Every Graco airless sprayer on this site falls into one of three lines: Homeowner (Magnum, Project Painter Plus, TrueCoat), Contractor/Prosumer (Ultra Max II, 390/395/695 series), or Gas-Powered (GMAX II, DutyMax). Each has its own dedicated parts section, sized to that machine's duty cycle. If you already know your model number, skip straight to the Order by Parts Diagram tool — it's faster than browsing by category.
With well over a thousand individual parts listings across the site, it's easy to land on the wrong category page before finding what you actually need. This guide maps the entire catalog into three main lines, so you know exactly which section to search first.
1. Homeowner Line
Built for weekend projects and occasional use rather than daily job-site duty. This category covers the Magnum family, Project Painter Plus, and TrueCoat handheld sprayers.
Magnum X5 / X7
The most common homeowner models, each with a dedicated exploded parts diagram.
Project Painter Plus
Entry-level stand sprayer; shares tip guards and inlet strainers with other homeowner models.
TrueCoat (Handheld)
Cup-fed handheld sprayers — simpler internal structure than bucket-fed stand models.
The full homeowner category, including maintenance schedules and cross-model accessory notes, lives at Graco Homeowner Paint Sprayer Parts.
2. Contractor / Prosumer Line
Built for daily or near-daily use, this category covers the Ultra Max II family and the 390/395/695 series machines used by painting contractors and maintenance crews.
| Model Family | Typical Use |
|---|---|
| Ultra Max II 490/495/595 | Mid-size contractor rigs, frequent daily use |
| Ultra Max II 695 (Standard, ProContractor, Hi-Boy) | Larger cart-based rigs for heavier volume |
| 390 / 395 Series | Long-standing contractor workhorse, electric-powered |
The 390 series category page notes direct cross-fit with the X7/LTS 17 diagram components and even the gas-powered 7900 on certain fittings — see Graco 390 Series Electric Airless Sprayer Parts for the specific overlap.
3. Gas-Powered Line
For large-scale jobs where voltage drops or limited flow aren't an option — block-fill, fireproofing coatings, stadium-wide striping. This category covers the GMAX II and DutyMax families.
GMAX II 5900 / 7900
Honda-powered engines driving heavy-duty piston pumps rated up to 2.35 GPM and 3,300 PSI.
DutyMax EH300 / GH Series
Hydraulic motor and displacement pump systems for the heaviest-duty applications on this site.
The Endurance Chromex pump rebuild kit, 15H240, is rated for 500+ gallons between repacks — a meaningfully longer service interval than standard rebuild kits, worth considering for gas-powered machines running high volume.
Full gas-powered category details are at Gas Airless Paint Sprayers & Parts.
4. What Crosses Over Between Lines
Graco standardizes certain accessory components across tiers more than most owners expect:
- Tip guards: RAC IV/5 guards used on the homeowner Project Painter Plus also fit the contractor-grade Ultra Max II 695 ProContractor.
- Low-pressure tip sets: The same low-pressure tips used across homeowner and prosumer lines reduce overspray consistently regardless of which pump is driving them.
- Manifold filters: The 390 series shares its manifold filter design with both the X7/LTS 17 diagram parts and, on certain fittings, the gas-powered 7900.
Pump cylinders, drive systems, and engine/motor components are line-specific and not interchangeable across homeowner, contractor, and gas-powered tiers, even when accessories look similar.
5. The Fastest Way to Find Your Category
- If you know your exact model number, skip categories entirely and use the parts diagram search tool.
- If you're not sure which line your machine belongs to, check the serial tag — model number prefixes generally correlate with a specific line (Magnum, Ultra Max II, GMAX, DutyMax).
- If still uncertain, call 713-931-4102 with a description of the machine — an advisor can place it in the right category in under a minute.

What are the three main lines of Graco airless sprayers?
Homeowner (Magnum, Project Painter Plus, TrueCoat), Contractor/Prosumer (Ultra Max II, 390/395/695 series), and Gas-Powered (GMAX II, DutyMax). Each has its own dedicated parts category.
Do homeowner Graco sprayer accessories work on contractor machines?
Some do — certain tip guards and low-pressure tips used on homeowner models are also compatible with contractor-grade machines, since Graco standardizes some accessory components across tiers.
Where do I start if I don't know which category my sprayer belongs to?
Use the Order by Graco Sprayer Parts Diagram tool and search by your exact model number — it routes you to the correct diagram and category regardless of which line the model belongs to.
Are gas-powered Graco sprayer parts different from electric ones?
The fluid section is often shared or closely related across families, but engine, drive, and fuel-system components are unique to gas-powered units and not found on electric machines.
