1. Fluid Section & Pump Components
The heart of your sprayer’s performance lies in its fluid section:
-
Piston rods, seals, and O-rings – Precision components (e.g. O‑ring packing 103413; cap sealing washer 115099) ensure leak-free, high-pressure sealing in the fluid section
-
Inlet strainers and manifolds – Graco 235004 inlet strainer and barbed deflector 244035 keep debris out while preserving flow consistency
-
Drive housing & repair kits – The 24W817 drive housing kit and 24W640 connecting rod are essential for fluid section rebuilds, available individually or teamed with full graco pump repair kits
Using certified OEM parts ensures pressure longevity and avoids the inefficiencies of aftermarket clones.
2. Power & Control Systems
Every sprayer relies on precise motor control:
-
Motor thrust bearings & thrust washers – Frequent replacement items like part numbers 107434, 116073, 116074, and 116079 maintain motor smoothness on heavy use
-
Control boxes & electronics – From power cord assemblies and on/off switches to pressure transducer and potentiometer modules, SprayersAndParts.com stocks full graco airless spray gun control components.
Maintaining these systems prevents voltage irregularities, keeps speeds consistent, and preserves spray quality.
3. Frame, Hoses & Mounting Hardware
Mobility and structural integrity are key:
-
Suction/drain hoses & clips – Replacement assemblies with spring clip retainers (195400) and prime hose setups ensure efficient cleaning and fluid handling.
-
Frame mounts & pail hangers – Durable parts like part 17C990 and rubber grip handles offer stability on tough job conditions.
4. Spray Gun: SG3 with 517 RST Tip
Every kit includes the iconic graco airless spray gun—SG3 with 517 stainless reversible tip—for professional-grade finish consistency. Upgrades and airless paint sprayer attachments like RAC‑X guards and multi-purpose whips also integrate seamlessly into the 190 PC system.
5. Complete Graco Pump Repair Kits

A pump kit combined with the drive housing and rod components maintains OEM reliability.

Multiple mesh filters (60–200 mesh suggested)

Compatible OEM parts like 243080 fluid filters and 235004 strainers

Quick-clean prime valve assemblies to prevent costly clogging
These items are essential airless paint sprayer attachments to ensure smooth, uninterrupted operation.
