Graco spray parts fall into five categories: spray tips & guards (shape the fan pattern), spray guns & gun parts (trigger, needle, seat, seals), filters & strainers (catch debris before it clogs the tip), hoses & fittings (deliver pressurized fluid to the gun), and pump & manifold components (the machine's internal fluid section). If you're new here, start by identifying which category your problem falls into — it narrows the search from hundreds of parts to a handful in seconds.
If you're new to Graco equipment, the parts catalog can look overwhelming at first glance — hundreds of listings, similar-looking part numbers, and terminology that assumes you already know what you're looking for. This overview breaks the entire catalog down into five categories, with real part numbers as examples, so you can walk in knowing exactly what section you need.
1. Spray Tips & Guards
The spray tip is the small, precisely-machined insert at the front of the gun that shapes the fan pattern and controls how much material comes out. Tips are sized by two numbers: the first digit(s) indicate fan width, the last two or three indicate the orifice size in thousandths of an inch. A wider fan and larger orifice mean more material per pass — useful for large flat surfaces, but too aggressive for fine trim work.
| Part | Part Number | Use Case |
|---|---|---|
| RAC X SwitchTip (reversible, general use) | LTX311 | Standard latex and stains, general exterior/interior work |
| Fine Finish Low-Pressure Tip | FFLP112 | Cabinets, furniture, fine finish work at lower pressure |
| SwitchTip, .009 orifice | LTX209 | Fine detail, thin coatings, small trim |
| RAC X Tip & Guard Combo, .015 | 246215 | General-purpose tip pre-paired with a guard |
The tip is the wear item that eventually needs replacing as it widens with use. The guard is the plastic housing that holds it and provides the safety shield — it lasts much longer and is usually only replaced if cracked or lost. Confirm which one you actually need before ordering.
2. Spray Guns & Gun Parts
Graco's airless gun lineup includes the SG2, SG3, SGPro, SG20, Contractor PC, and FTX families. Most gun-related repairs come down to one of three failure points: a worn needle/seat causing drips after the trigger releases, a stiff or unresponsive trigger, or a leaking swivel connection where the hose meets the gun.
Dripping After Trigger Release
The most common gun complaint. Almost always a worn needle and seat, not a pump issue. Repair kit 288817 covers SG2/SG3/SG20/SGPro; Contractor/FTX guns use a separate kit.
Leaking at the Swivel
The connection where the hose rotates against the gun. Worn O-rings here let paint escape under pressure — a small, inexpensive fix once identified.
Stiff or Unresponsive Trigger
Usually dried paint or a worn spring in the trigger assembly. A full trigger kit resolves this faster than trying to clean the existing one repeatedly.
For the complete gun parts breakdown, repair kit numbers by gun model, and full diagnostic steps, see the Graco Spray Gun Parts page.
3. Filters & Strainers
Filters exist at two points in the system: an inlet strainer at the pump intake, and a gun filter inside the gun handle. Both catch debris before it reaches the tip, and both are rated by mesh size — the higher the mesh number, the finer the filtration.
| Filter | Part Number | Mesh | Best For |
|---|---|---|---|
| Gun filter, SG-series guns | 288749 | 60-mesh | Standard latex |
| Gun filter, SG-series guns | 288750 | 100-mesh | Fine finish coatings |
| Short horizontal manifold filter | 243080 | 60-mesh | Pump inlet filtration |
| Tip filter | 238562 | 100-mesh | Fine finish, in-line before the tip |
A clogged filter causes symptoms that look alarming — reduced pressure, uneven fan, spitting — but resolve completely with a two-minute swap. Check the filter before assuming anything more serious is wrong.
4. Hoses & Fittings
Airless hoses are rated for high pressure (typically 3,300+ psi) and come in different lengths and diameters. A shorter "whip hose" is often used between the main line and the gun to reduce operator fatigue and improve maneuverability, especially on detail work or overhead spraying.
- Main line hose: connects the pump to the whip hose or directly to the gun; length affects both reach and pressure drop over distance
- Whip hose: a short (typically 2-4 ft) flexible section at the gun end that reduces strain during continuous use
- Swivel fittings: allow the hose to rotate at connection points without kinking or twisting
Full hose specifications and gas/electric-specific fitting requirements are covered on the Gas Airless Paint Sprayer Parts page and the Graco Accessories category.
5. Pump & Manifold Components
This is the machine's internal fluid section — pistons, packings, prime valves, and the manifold that routes fluid to the outlet. These are the parts most owners are least familiar with, since they're inside the housing rather than visible during normal use.
| Component | Part Number | Fits |
|---|---|---|
| Manifold filter assembly & return valve | 15G455 | Ultra 395/495/595 and related models |
| Manifold return valve (alt. number) | 287167 | Same family as above |
Pump and manifold parts are the least standardized across models — always confirm against your specific machine's parts diagram rather than assuming compatibility from a similar-looking part.
6. What to Order First as a New Customer
If you're setting up a maintenance stock for the first time rather than chasing a specific repair, this is a sensible starting order that covers the most common failure points across categories:
- One spare tip matched to your most common coating type
- 2-3 gun filters in the mesh size matching your gun model
- One inlet strainer
- A gun repair kit matched to your specific gun model (SG-series vs. Contractor/FTX)

What are the main categories of Graco spray parts?
Five categories: spray tips & guards, spray guns & gun parts, filters & strainers, hoses & fittings, and pump/manifold components. Most repairs only touch one or two of these.
Which Graco spray part wears out fastest?
Filters and spray tips, since both are direct-contact consumables. Tips widen gradually with use; filters clog with paint debris. Both are inexpensive, expected replacements — not signs of a bigger problem.
Do all Graco spray guns use the same filter?
No. SG2, SG3, SG20, and SGPro guns typically share one filter family; Contractor PC and FTX guns use a different one. Confirm your gun model before ordering.
What's the difference between a spray tip and a tip guard?
The tip shapes the fan pattern and controls flow — it's the wear item. The guard is the housing around it, providing safety shielding and holding the tip in place. They're sold separately but always used together.
