Graco 495 PC Lo-Boy Sprayer Parts

Graco 495 PC Lo-Boy Sprayer Parts: OEM Reliability

Graco Ultra Max II 495 PC Lo-Boy is famous among repaint pros for its “just-right” balance of muscle and maneuverability. A 1.2 hp MaxPower™ brushless motor drives an Endurance™ Chromex pump that delivers 0.60 gpm through tips up to 0.025 in. while holding a rock-steady 3,300 psi. That’s enough output to spray a 2,500 sq ft home before lunch—without the bulk of a two-gun rig.

But big-name productivity crashes the moment a three-dollar O-ring fails. SprayersAndParts keeps every component on the official Graco 495 PC Lo-Boy parts list—from 17C487 ProConnect pumps to 18B260 packing cartridges—on the site and ready to ship. 

Why Stick with Genuine Parts?

• Chromex-hardened rods resist abrasive fillers and extend pump life up to twice as long as aftermarket chrome-plated steel.
• V-Max Blue™ leather/PTFE packings keep seals tight for 200-plus operating hours—copycat Teflon rings leak in half that time.
• SmartControl™ 3.0 sensors require factory impedance to hold pressure within ±1 %; off-brand sensors drift and leave tiger stripes in satin finish.
• Warranty integrity—Graco backs the drive train sprayer only when you document OEM parts.

Core Specifications at a Glance

Lo-Boy’s low centre-of-gravity cart slides under van shelving yet tows a 50-ft hose and gun on the same handle, keeping crews nimble on townhouse stairwells.

Cross-Fleet Compatibility That Shrinks Van Inventory

Your service van probably carries a mix of Graco airless paint sprayers—maybe a beefy GMAX II 7900 gas rig for elastomerics, a cordless Project Painter Plus for punch-outs, and a FieldLazer S100 striping rig for the athletic-field contract. Luckily, more parts overlap than you’d think:

• The 17C487 pump also bolts onto 390 PC, 395 PC and even the 7900 Graco paint sprayer for emergency field swaps (flow is lower on gas frames; size tips accordingly).
• V-Max packings, inlet balls and springs match those in the GMAX 7900 and Ultra Max II 695 pumps—one box protects three revenue streams.
• Graco extension tools (20- or 30-in. CleanShot poles) thread straight into the Contractor PC gun, so you can back-roll high walls without ladders.
• RAC X LP tips and 60-mesh gun filters migrate from the Lo-Boy to Graco Project Painter Plus parts, letting you carry one wallet of tips for fine-finish and production.
• Graco FieldLazer S100 uses the same SG2/SG3 gun seals—no special kit needed for sideline touch-ups.

Order-by-Diagram: One-Tap Accuracy

Copy-pasting long part numbers on a smartphone invites typos. Our interactive Order By Graco Parts Diagram overlays the official exploded view on every product page: tap the piston rod, filter, or o-ring you need and it lands in your cart pre-formatted—no guesswork. Superseded SKUs are flagged automatically, so you never ship an obsolete seal kit to a job 200 miles away.

Maintenance Blueprint for Zero Surprises

Daily

Run FastFlush™ 60 sec, relieve pressure, add two drops of TSL throat lube and wipe the piston rod.

Weekly

Replace 60-mesh manifold filter; back-flush gun; inspect hose jackets and extension-tool gaskets.

200 hrs

Install 18B260 packing cartridge; polish cylinder sleeve; check Advantage Drive belt tension.

500-700 gal

Drop in a fresh 17C487 pump—five minutes, one wrench, no vise. Record gallons in BlueLink™ for warranty traceability.

Pro Tips from the Field

• Color-code bins: blue for graco parts replacement, red for gun kits, green for Project Painter Plus items—techs grab right the first time.
• Pair every seal kit with fresh lube. A $10 bottle of TSL can save a $400 pump from dry-run burn-out.
• Swap inlet strainers, not just filters. A crushed 60-mesh strainer starves the pump and fakes a pack-off failure.
• Use a 20-in. extension tool on soffits. It speeds coverage by 30 % and keeps overspray off staging planks.
• Keep a Project Painter Plus gun in the van. Its RAC IV tips double as emergency backups for the Lo-Boy when the nearest dealer is hours away.

Frequently Asked Questions

Can the 495 PC spray hot solvents?

Yes—Chromex rods and PTFE/leather packings handle material up to 110 °F; always flush with mineral spirits, not lacquer thinner.

Will the Lo-Boy pump fit my stand-mount 495?

Absolutely. The 17C487 ProConnect pump fits stand, Lo-Boy, and Hi-Boy frames built after 2015.

What generator size keeps full pressure?

A 3.8 kW inverter handles start-up inrush and maintains 3,300 psi without brown-outs.

Which mesh filter for elastomeric?

Use 30-mesh inlet strainer and 60-mesh manifold screen; anything finer starves the pump.

Do RAC-X tips fit FieldLazer S100?

Yes—the S100 shares RAC X guards, so one tip wallet works across line-stripers and wall sprayers.
