Whether you're a seasoned paint contractor or a passionate DIYer, maintaining your Graco spray equipment is key to achieving professional results on every job. The Graco 650 PC Pro is a mid-sized powerhouse, and this Parts 2 breakdown gives you an in-depth look at its essential components—perfect to extend the life of your unit, optimize performance, and reduce downtime.
The Parts 2 section is all about finer details. These paint sprayer parts complement what's covered in Parts 1, including:
Control components, knobs, and switches
Manifold hardware and fittings
Suction/filter accessories
Valve kits and seals
Mounting hardware such as screws, clips, and caps
This level of detail is designed to align seamlessly with the official Graco parts list, helping you pinpoint exactly what you need without guesswork.
The control section includes small but critical parts:
Pressure control knobs – precision potentiometers to set your spray pressure
Toggle switches, relays, wiring harness connectors – ensures safe and smooth operation
Digital display components – key for SmartControl models
Control box bushings and transducer grommets – essential graco sprayer accessories to protect wiring against wear and tear
These parts are vital for maintaining consistent output from your machine. Replacing worn knobs or faulty relays can restore full functionality and prevent electrical failures.
Fluid pathway integrity is paramount to a smooth finish. From inlet to outlet, key parts include:
O-rings and sealing kits compliant with the Graco parts list
Manifold filters, filter caps, and back-up seals
Inline strainers and pipe fittings such as nipples and adapters
Ensuring these components are in peak condition helps maintain even pressure flow and prevents debris from reaching your graco spray tips.
Spray valves are the gatekeepers of precision. In this section:
Valve seats and gasket kits restore fluid handling integrity
Rebuild kits include multiple seals and seats—perfect for DIY Graco pump repair kits
Critical for preventing leaks and ensuring reliable shutoff pressure
Replacing seats at the first sign of leakage saves you from frustrating spray issues later.
Although simple, these small parts make a big difference:
Suction tube clips and drainage tubing
Protective caps and small brackets
Ordering these paint sprayer parts ensures your system continues efficient fluid intake without interruptions
These are often overlooked but essential parts of any maintenance routine.
Even the smallest screw has an impact:
Hex washer screws, tapping screws, grooved pins
Clip assemblies, hose clips, drip tray caps
These graco sprayer accessories hold everything securely, reducing vibration-related wear and facilitating clean assembly
Replacing bent or worn hardware ensures your rig remains job-ready and rock-solid.
Using genuine OEM components means:
Guaranteed compatibility – exact fit as indicated in the factory graco parts list
Durability under pressure – designed for airless systems up to 3,300 psi
Warranty integrity – aftermarket parts can void warranties
Performance assurance – fluid flow and tip patterns remain consistent
Simplified ordering – exact part numbers make replacements quick and accurate
