Graco spray guns split into two repair-kit families: SG2, SG3, SG20, and SGPro guns use repair kit 288817, while Contractor and FTX guns use 288488. Filters, trigger parts, and swivel kits are more universal and often cross both families. Always confirm your exact gun model — printed on the gun body — before ordering, since a kit built for the wrong family won't seat correctly even though it looks similar.
Graco's airless spray gun lineup looks more unified from the outside than it actually is internally. Two guns that look nearly identical can require completely different repair kits, while other components — filters, trigger guards — cross over cleanly between them. This reference lays out exactly what's compatible with what, using real part numbers, so ordering isn't a guess.
1. The Two Gun Families
SG-Series (SG2, SG3, SG20, SGPro)
Graco's most common homeowner and prosumer gun line, typically bundled with Magnum and mid-range Ultra sprayers. Shares one core repair kit family.
Contractor / FTX
The contractor-grade gun line, built for higher-volume daily use. Uses a separate repair kit family from the SG-series, despite looking visually similar.
2. Repair Kit Compatibility Table
| Part Number | Description | Compatible Guns |
|---|---|---|
| 288817 | Gun Repair Kit (needle, seat valve, nyloc nut) | SG2, SG3, SG20, SGPro |
| 243092 | Alternate repair kit, slightly different components | SG2, SG3 |
| 288488 | Gun Repair Kit for Contractor/FTX | Contractor, FTX |
| 218070 | Gun Needle-Diffuser Seat Kit (cross-family) | Contractor, FTx, FTx-E, Contractor ST, SG2, SG3 |
Part 218070 is one of the few genuinely cross-family kits, covering both SG2/SG3 and Contractor/FTX guns. This is an exception because it addresses a specific needle-and-seat assembly rather than the full repair kit — don't assume other kits share this same cross-compatibility.
3. Parts That Fit Across Both Families
| Part | Part Number | Notes |
|---|---|---|
| Gun Filter, 60-mesh | 288749 | Standard latex; fits all Graco gun models |
| Gun Filter, 100-mesh | 288750 | Fine finish coatings; fits all Graco gun models |
| Sleeve Seal | 179733 | Prevents leaks between gun body and handle |
| Trigger Guard | 195495 | Safety component, broadly compatible across models |
The internal filter cavity is standardized across nearly every current Graco gun model, which is why the 288749/288750 filters are the single most universally compatible part on this list — a safe default stock item regardless of which gun family you're servicing.
4. Parts That Are Not Interchangeable
| Part | Part Number | Fits |
|---|---|---|
| Gun Trigger Repair Kit | 243639 | SG-series only — not a Contractor/FTX fit |
| Gun Swivel Repair Kit | 238817 | Model-specific — confirm gun family before ordering |
| Gun Inlet Adapter | 195384 | Model-specific fitting, not universal |
These parts are easy to mis-order specifically because they look interchangeable at a glance. Confirming your gun's exact model before ordering avoids the return-and-reorder cycle these three cause most often.
5. How to Confirm Your Gun Model
- Check the label printed directly on the gun body, typically near the handle or trigger guard.
- If the label has worn off, compare the trigger guard shape and overall gun profile against reference photos — SG-series and Contractor/FTX guns have visibly different guard styles.
- If still unsure, call 713-931-4102 with a description of the gun and the sprayer it came with — an experienced advisor can usually confirm the family in under two minutes.

Which Graco gun repair kit fits my spray gun?
288817 fits SG2, SG3, SG20, and SGPro guns. 288488 fits Contractor and FTX guns. An alternate kit, 243092, also fits SG2/SG3 with slightly different components. Check the model label on your gun body before ordering.
Do Graco gun filters fit every gun model?
Yes — 288749 (60-mesh) and 288750 (100-mesh) fit across SG2, SG3, SGPro, SG20, Contractor, and FTX guns, since the filter cavity is standardized across these models.
Can I use a Contractor gun repair kit on an SG2 or SG3 gun?
Not directly. 288488 is built for Contractor/FTX; SG2/SG3/SG20/SGPro use 288817. Some needle-and-seat kits like 218070 are cross-compatible, but full repair kits are not.
Where is the model number on a Graco spray gun?
Printed on a label on the gun body, near the handle or trigger guard. If worn off, the gun's shape and trigger guard style can help narrow it down, but confirming the printed model number is most reliable.
