Five Wagner Replacement Parts Every Painter Should Own
Whether you’re rolling up to a commercial repaint or knocking out a weekend deck-stain project, your Wagner airless sprayer is the workhorse you can’t afford to sideline. Yet most breakdowns trace back to a handful of wear components that cost pennies compared with a missed deadline or an angry client. Below, we dive deep into five OEM parts Benny’s Spray Center keeps on the shelf—and why slipping them into your toolbox today could save you hours of frustration tomorrow.
1. Gun Filters, White 50-Mesh (2-Pack) — OEM #0516733
The gun filter is your sprayer’s final checkpoint before paint exits the tip. Wagner’s white 50-mesh insert catches dried pigment skins, rust flecks, and bucket debris that even a strainer bag can miss. When contaminants reach the tip they cause “spitting” and a frown-shaped fan, forcing you to stop and pick out clogs mid-stroke. Swapping filters every few gallons, or at the first sign of a pressure flutter, keeps the fan razor-uniform and reduces overspray touch-ups. Because this OEM element is precision-sized for the gun’s bore, it seats perfectly—no bending the screen or fighting leaks around the gasket. Keep a couple of twin-packs in your rig and treat them like printer ink: cheap, plentiful, and instantly fixes 80 percent of quality issues. bennysspraycenter.com
2. Inlet Strainer, 1-5/16″ Thread — OEM #5006536
Think of the inlet strainer as a goalie that never leaves the net. Sitting at the very bottom of the siphon tube, this stainless-steel screen blocks marble-size chunks of dried coating and job-site grit before they ever touch the pump packings. A torn or missing strainer turns every prime into Russian roulette—one stray chip can score the piston rod or pit valve seats and cut your pump life in half. Wagner’s OEM version threads directly into the pickup tube so it won’t snap off during aggressive bucket changes. Rinse it after each shift; replace it when the mesh bows or you spot pinholes. At barely ten bucks, it’s the cheapest insurance you can buy against a $300 pump rebuild. bennysspraycenter.com
3. Lower Packing Assembly — OEM #0551539
Packings are the heart valves of an airless sprayer, sealing high-pressure fluid around the piston on every stroke. Over hundreds of gallons they compress, scratch, and finally leak—first as a subtle pressure dip, then as a full-blown geyser of wasted material. Wagner’s lower packing assembly comes pre-stacked with genuine leather, PTFE, and backup washers in the exact order called for at the factory, so you’re not guessing which lip faces where. Drop-in replacement takes less than 30 minutes with a packing tool and basic wrenches, restoring the pump’s ability to hit and hold its rated PSI. Pair it with fresh throat seal fluid and you’ll push primer as smoothly in month 60 as you did on day one. bennysspraycenter.com
4. Piston Rod for EPX2155/2255, SW419 — OEM #0551537
Even the world’s best packings can’t save a gouged piston rod. Once the chrome plating wears or a scoring line forms, every down-stroke drags a new scar across the seal stack, creating a pressure-robbing bypass that snowballs fast. This OEM stainless rod is factory-machined to Wagner’s concentricity spec—critical for holding 3,000+ PSI without wobble. The beveled nose slips smoothly through fresh packings, reducing installation risk, and its integrated threads accept the original piston valve without shims. Contractors often run a tired sprayer “one more job” to avoid the cost, but a rod swap is still a fraction of buying a new rig—and cheaper than a rental if the current pump dies mid-project. bennysspraycenter.com
5. Spray-Gun Rebuild Kit (G-10XL, G-12XL, AG-08) — OEM #0556038
A draggy trigger or tailing fan often signals that the spray gun—not the pump—is begging for service. Over thousands of cycles, the needle tip dulls, the spring sags, and miniature O-rings harden until paint weeps down the handle. Wagner’s complete rebuild kit bundles a fresh carbide needle, stainless seat, calibrated spring, and all elastomers so you restore factory snap-off in one go. Rebuilding instead of replacing saves roughly 70 percent over a new gun and lets operators keep the grip they’re already comfortable with. Do the overhaul at season’s end or whenever you notice the fan curling at the edges, and you’ll cut edge-banding work on every wall you spray next year. bennysspraycenter.com
Pro Tips for Stocking and Swapping Parts
- Buy two of everything. Keeping a “hot spare” on the shelf means zero downtime if the first filter tears or the packing install goes sideways.
- Create a maintenance log. Date-stamp each part change—filters, strainers, packings, rod—to predict the next swap and order early.
- Bundle shipping. Benny’s offers free freight over $179; tossing small items into the cart with larger parts often pushes you past the threshold and saves a future shipping fee.
- Lean on the experts. Not sure which rod fits your exact EPX model? Call Benny’s certified techs—real people who wrench these sprayers every day and can walk you through the SKU maze.
