Your One-Stop Source for OEM Graco 190PC Lo-Boy Electric Airless Sprayer Parts & Kits
Graco 190PC Lo-Boy is the lightest professional-grade sprayer Graco makes—just 14 kg / 30 lb—yet it still drives a 0 .021″ tip at 3300 psi thanks to its 5⁄8-hp DC motor. That translates to a usable flow of 1.8 L / min (0.47 gpm), the sweet-spot for residential repaints, small commercial interiors and remote punch-list jobs. The Lo-Boy frame straddles a 19-litre pail so you can roll and spray without lifting buckets up to a stand cart.
Why Choose Genuine Graco 190PC Parts?
- Endurance™ Pump with Chromex Rod — lasts 2 × longer than aftermarket steel; V-Max Blue™ packings shrug off grit and hot solvents.
- ProConnect™ one-minute pump swap keeps you spraying instead of driving to service centres.
- Advantage Drive™ gears run whisper-quiet and carry a lifetime warranty.
- Easy-Out™ Filter bleeds from the inside out, purging debris with a fraction of the flush water.
- SmartControl 2.5 holds fan width steady within ±1 %—critical when you’re feathering join lines on cabinets.

Compatible Rigs You Can Cover with the Same Parts Shelf
Graco standardises hoses, guns and guards across its small-electric family, so stocking 190PC spares also keeps these money-makers running:
- Graco Magnum X7 — use the graco magnum x7 replacement spray gun or RAC IV tips on either rig.
- Graco Magnum LTS 17 — identical piston seals; our graco magnum lts 17 parts diagram shows cross-references.
- Graco 230 Paint Sprayer — shares 50-mesh gun filters and BlueMax™ hoses.
- Graco 3400 LineLazer — manifold ball, suction tube and graco 3400 parts match the 190PC’s pump thread.
Accessory Upgrades That Pay for Themselves
- RAC X LP Tips & Guards — spray at 50 % lower pressure for 2 × tip life and 30 % less overspray; pair with our graco paint sprayer guard catalogue.
- Contractor PC Gun plus graco nozzles and tips kit—20 % lighter trigger force keeps wrists fresh on long cut-ins.
- 15 m BlueMax II Hose + 0.9 m Whip — reduce hand torque while keeping pressure solid at the gun.
- SmartStart™ Cordless Pressure Monitor — log gallons and hours to the BlueLink app for predictive maintenance.
- Power Flush Adapter — hooks to a garden hose; cut cleanup water use by 40 %.
Maintenance Blueprint for Zero Downtime
- Daily — Flush with warm water or mineral spirits, then add five drops of TSL at the wet-cup.
- Every 200 h — Swap the Easy-Out filter; colour-code filters to material families to avoid cross-contamination.
- Every 500 h — Repack the pump with the QuikPak cartridge (10 min, no vise).
- Quarterly — Inspect drive gears; Advantage Drive’s hardened steel should show no wear—if it does, you’re under-lubricating.
- Annually — Replace suction & drain tubes, O-rings, and graco paint sprayer attachments that contact solvent-borne coatings.
Frequently Asked Questions
Will 190PC parts fit my older 190 ES or 210 ES?
Yes—the pump thread and drive pin are unchanged since 2010. Just confirm you have the ProConnect door; retrofit kit 17J872 updates early frames.
What’s the longest hose I can run?
A 50 ft × ¼″ main with a 3 ft whip keeps 2800 psi at a 0 .019″ tip. For 100 ft runs step up to 3⁄8″ main hose.
Can I spray elastomeric roof coatings?
Stay within 0 .021″ tip and keep viscosity under 110 KU; otherwise step up to a Graco 230 paint sprayer with a 0 .027″ tip.
How do I cross-reference RAC IV to RAC X tips?
Subtract 6 from the RAC IV size; e.g., a 515 IV equals a 209 X LP—our graco spray tips and guards chart lists every conversion.
