Every Graco part belongs to one of seven functional categories: pumps & repair kits, spray guns & gun parts, tips & guards, filters & strainers, valves, seals & packings, and hoses & fittings. Identifying which category your problem falls into narrows the search from thousands of parts to a handful in seconds. This index covers all seven with real OEM part numbers for each.
Graco's catalog runs to tens of thousands of individual components, which makes searching by part name alone slow and error-prone. Organizing by function instead — what the part actually does inside the machine — is dramatically faster. This index maps every major category with genuine OEM part numbers you can order directly.
1. Pumps & Repair Kits
The fluid section is the heart of any airless sprayer: a piston rod moving inside a hardened cylinder, pulling material in on the downstroke and pressurizing it on the upstroke. Most pump problems are wear-item problems, not full-pump failures, which is why repair kits usually make more sense than replacement.
| Component | Part Number | Fits |
|---|---|---|
| Displacement Pump | 239769 | Ultra Max II 695, Series A-G frames |
| Pump Repair Kit | 248212 | 695 and 795 — shared kit |
| Endurance Pump Repair Kit | 255204 | Long-life option for high-volume use |
| Endurance Chromex Rebuild Kit | 15H240 | Rated 500+ gallons between repacks |
| Magnum Pump Repair Kit | 17V781 | Select Magnum series machines |
| Motor Repair Kit | 17L282 | Magnum X5, X7, LTS 15 |
| Pump Inlet Valve Kit | 16E844 | Magnum X5 / LTS 15 |
| Pump Outlet Valve Kit | 16E845 | Magnum X5 / LTS 15 |
| Displacement Pump | 246428 | LineLazer 3400 striper |
Pump components wear as a system. A worn piston rod usually means the cylinder has scoring too. Repair kits bundle the parts that fail together, which is both cheaper and more complete than chasing one component at a time.
2. Spray Guns & Gun Parts
Graco's gun lineup splits into two repair families that are not interchangeable, despite looking similar: the SG-series (SG2, SG3, SG20, SGPro) and the contractor-grade Contractor/FTX line.
| Component | Part Number | Fits |
|---|---|---|
| Gun Repair Kit | 288817 | SG2, SG3, SG20, SGPro |
| Gun Repair Kit | 288488 | Contractor, FTX |
| Needle-Diffuser Seat Kit | 218070 | Cross-family: Contractor, FTx, ST, SG2, SG3 |
| Trigger Repair Kit | 243639 | SG-series |
| Swivel Repair Kit | 238817 | Model-specific — confirm gun family |
| Trigger Guard | 195495 | Broadly compatible |
| SG2 Spray Gun (complete) | 243011 | Ships with most Magnum models |
| SG3 Spray Gun (complete) | 243012 | Drop-in upgrade from the SG2 |
Assuming an SG-series kit fits a Contractor or FTX gun. They look similar externally but use different internal geometry. Kit 218070 is one of the few genuine cross-family exceptions — most others are not.
3. Tips & Guards
The tip shapes the fan pattern and controls flow rate. Graco tip numbering is readable once you know the system: the first digit doubled gives fan width in inches, the last two digits give orifice size in thousandths of an inch. A 515 sprays a 10-inch fan through a 0.015-inch orifice.
| Tip | Part Number | Typical Use |
|---|---|---|
| RAC X SwitchTip 515 | LTX515 | Standard interior latex |
| RAC X SwitchTip 517 | LTX517 | Interior/exterior latex workhorse |
| RAC X SwitchTip 519 | LTX519 | Exterior siding, light elastomeric |
| RAC X SwitchTip 521 | LTX521 | Elastomeric stucco, masonry |
| RAC X SwitchTip 415 | LTX415 | Interior walls, deck stain |
| RAC X SwitchTip 413 | LTX413 | Deck stains, fence rails |
| Fine Finish Low Pressure 310 | FFLP310 | Varnish, lacquer, precise trim |
| Fine Finish Low Pressure 208 | FFLP208 | Fine finish, thin coatings |
| RAC X Tip & Guard Combo, .015 | 246215 | Tip pre-paired with guard |
4. Filters & Strainers
Filtration happens at two points: an inlet strainer at the pump intake and a gun filter inside the handle. Higher mesh numbers mean finer filtration. This is the single cheapest category to keep stocked, and the most common cause of problems that look far more serious than they are.
| Component | Part Number | Mesh / Fits |
|---|---|---|
| Gun Filter | 288749 | 60-mesh — standard latex, fits all Graco guns |
| Gun Filter | 288750 | 100-mesh — fine finish, fits all Graco guns |
| Manifold Filter | 243080 | 60-mesh — pump inlet filtration |
| Tip Filter | 238562 | 100-mesh — in-line before the tip |
| Inlet Filter / Strainer | 288716 | 3/4-inch — Magnum X5, LTS 15 |
A partially clogged filter produces symptoms that look alarming — pressure loss, uneven fan, intermittent spitting — but resolve entirely with a two-minute swap. Make this the automatic first check on any performance complaint.
5. Valves
Check-ball valves control fluid direction through the pump, while prime and drain valves handle startup and cleanup. A machine that primed fine last season but won't hold prime after storage is almost always a valve issue, not a failing pump.
| Component | Part Number | Fits |
|---|---|---|
| Drain Valve Assembly | 235014 | 695 platform |
| Prime/Drain Valve Kit | 239914 | 695 and 390 PC platforms |
| Prime Valve Kit | 257352 | GMAX II filter-series machines |
| Magnum Prime/Drain Valve Kit | 17V783 | Magnum X5, LTS 15 |
| Prime Valve Seat | 15E022 | 390 PC Cordless and related electric models |
| Inlet Valve & Carbide Seat Kit | 246429 | Multiple pump series — confirm against diagram |
6. Seals, Packings & O-Rings
Packings seal the piston rod against pressure loss and are the pump's primary wear surface. Graco's general service guidance for these runs roughly every 100-200 gallons sprayed, though this varies significantly with coating type and operating pressure.
| Component | Part Number | Fits |
|---|---|---|
| Pump Packing Repair Kit | 18B260 | 390, Ultra 395/495/595, Ultra Max II 490/495/595, FinishPro 390/395 |
| Packing Repair Kit | 239939 | Ultra Max II 695 |
| Female Gland Packing | 176757 | Displacement pump fluid section |
| Male Gland Packing | 176754 | Displacement pump fluid section |
| O-Ring Packing | 17V093 | Displacement pump |
| Sleeve Seal | 179733 | Gun body to handle seal |
| Hydraulic Seal Set | 248977 | DutyMax GH hydraulic systems |
7. Hoses & Fittings
Airless hoses are pressure-rated components, not generic tubing — using an underrated hose is a genuine safety issue at 3,000+ PSI. Suction hose kits often bundle the small washers and fittings that would otherwise need separate ordering.
| Component | Part Number | Fits |
|---|---|---|
| Suction Hose Kit | 246386 | 390, 395, 490, 595, 695 — genuinely cross-platform |
| Suction Hose Kit | 249356 | LineLazer 3400 |
| Garden Hose Washer | 115099 | Included in kit 249356 |
| Gun Inlet Adapter | 195384 | Model-specific fitting |
| Return Hose Assembly | 244240 | Varies by cart configuration |
How to Find Your Exact Part
- Identify the category first using the seven sections above — is it gun-side, pump-side, or hose/fitting? This alone narrows most searches dramatically.
- Get your model number and series letter from the serial tag, usually on the cart frame or motor housing. The series letter affects compatibility on pump components.
- Open the parts diagram for your model and match the numbered callout to the failing component.
- Cross-reference the callout against the parts list to get the real part number, then confirm compatible models before ordering.
Filters, common tip sizes, and Pump Armor storage fluid (17S980 8oz / 243104 32oz) are compatible across most of the Graco lineup. Pump cylinders, gun assemblies, and suction tubes are usually model-specific.

Frequently Asked Questions
What are the main categories of Graco parts?
Seven functional categories: pumps and repair kits, spray guns and gun parts, tips and guards, filters and strainers, valves, seals and packings, and hoses and fittings. Nearly every repair draws from just one or two of these.
Which Graco parts wear out most often?
Filters, spray tips, and packings. Filters clog with normal use, tips widen as they wear and change the spray pattern, and packings wear continuously against the piston rod under pressure.
How do I know which Graco part number fits my sprayer?
Check the model number and series letter on the serial tag, then match against the exploded parts diagram for that model. The series letter matters — the same model number can have different part compatibility across production runs.
Do Graco parts cross over between different sprayer models?
Some do. Filters, common tip sizes, and Pump Armor are widely compatible. Pump cylinders, gun assemblies, and suction tubes are usually model-specific. Always confirm against your machine's diagram before ordering.
