Graco Sprayer Parts Guide: Pumps, Guns, Tips, Hoses, Filters & Repair Parts
A Graco paint sprayer is a system of components working together to move, pressurize, filter and spray coating material. Understanding the major Graco sprayer parts can make it easier to maintain your equipment, troubleshoot spray problems and identify the correct genuine replacement parts when service is required.
Looking for a Graco Replacement Part?
If you already know your Graco machine model or part number, you do not need to read the entire guide. Start with the appropriate parts catalog or accessory category and verify the component against your exact sprayer.
What Are the Main Parts of a Graco Paint Sprayer?
The exact construction depends on the machine, but a professional airless sprayer can be understood by looking at its major operating systems. These include the motor and drive system, piston pump, pressure control, filtration system, fluid hose, spray gun and spray tip.
1. Graco Pumps, Pistons & Fluid-Section Parts
The pump is one of the central components of an airless sprayer. It draws coating from the material source and delivers it under pressure through the fluid system.
Depending on the Graco model, serviceable pump components can include:
- Complete displacement pumps
- Pistons and piston rods
- Cylinders
- Intake and outlet valves
- Balls and seats
- Packings
- O-rings and seals
- Pump repair kits
Wear inside the fluid section may contribute to problems such as difficulty building pressure, pressure loss, leakage or reduced material delivery. The correct diagnosis should be based on the troubleshooting procedure for the exact machine rather than symptoms alone.
Do not select the component by appearance alone. Verify your complete Graco sprayer model and the pump or repair-kit part number first.

The airless spray gun acts as the operator-controlled valve at the end of the fluid system. Pulling the trigger allows pressurized coating to pass through the gun and spray tip.
Graco uses multiple spray-gun families across homeowner, contractor, industrial and finishing equipment. The correct gun should be selected according to the sprayer, pressure rating, application and compatible accessories.
Contractor PC Spray Guns
The Contractor PC platform is used with a number of professional Graco airless sprayers. Its serviceable design allows specified internal wear components to be replaced rather than automatically replacing the entire gun.
When selecting or servicing a spray gun, verify:
- Maximum working pressure
- Sprayer compatibility
- Hose connection
- Compatible spray-tip and guard system
- Gun filter requirements
- Exact Graco part number
3. Graco Spray Tips & Tip Guards
The spray tip controls two critical aspects of spraying: the amount of coating that can pass through the gun and the resulting spray-pattern width.
Tip selection should consider:
- Coating type and viscosity
- Required fan width
- Tip-orifice size
- Maximum tip size supported by the sprayer
- Desired finish
- Manufacturer recommendations
Graco offers tip families for different applications, including general-purpose airless spraying and low-pressure fine-finish work. The compatible tip guard holds the tip at the front of the gun.
4. Graco High-Pressure Spray Hoses
The fluid hose carries pressurized coating from the sprayer to the spray gun. Graco hoses are available in different lengths, inside diameters, pressure ratings and configurations.
Inspect high-pressure hoses regularly for abrasion, cuts, leakage, damaged fittings and other deterioration. Never operate an airless sprayer with a damaged hose or a hose that is not rated for the pressure produced by the machine.

Filtration helps prevent debris from reaching sensitive components and the spray tip. Depending on the Graco machine, filtration may occur at several points in the fluid path.
Inlet Strainers
An inlet strainer helps stop larger debris before material enters the pump.
Manifold Filters
Many professional sprayers use a manifold filter downstream of the pump. Available mesh sizes vary according to the machine and coating.
Spray Gun Filters
Some spray guns use an additional filter to help capture contamination before coating reaches the spray tip.
If a machine experiences repeated tip clogging, filters and strainers are among the components worth inspecting as part of the manufacturer's troubleshooting procedure.

The prime/drain valve is an important operating component on many airless sprayers. It is used during procedures such as priming and pressure relief.
A worn or damaged valve may contribute to priming or pressure-related problems. Because these components are model-specific, confirm the exact Graco machine and replacement part number before ordering.
7. Graco Packings, Seals & O-Rings
Packings, seals and O-rings help control fluid movement and maintain sealing surfaces within the pump and related assemblies.
Possible reasons to inspect these components include:
- Fluid leakage around the pump
- Difficulty maintaining pressure
- Reduced pumping performance
- Visible wear found during scheduled service
Packing arrangements differ between pumps, so use the repair kit or individual components specified for your exact machine.
8. Graco Pump Repair Kits
A complete pump does not always need to be replaced when service is required. Graco offers repair components and model-specific kits for many pump assemblies.
Before ordering a pump repair kit, confirm:
- Your complete sprayer model
- The machine part number when applicable
- The pump or fluid-section part number
- The correct repair-kit number
- The applicable parts diagram or service manual
9. Motors & Pressure-Control Components
Electric Graco airless sprayers use a motor, drive system and model-specific control components to operate and regulate the pump.
Depending on the machine, service components may include:
- Motor assemblies
- Control boards
- Pressure-control components
- Transducers
- Switches
- Power cords
- Displays
- Related electrical components
10. Suction Tubes, Drain Tubes & Intake Parts
Before coating can be pressurized, it must move from the material container into the pump. Depending on the machine, the intake system may include:
- Suction or intake tubes
- Inlet strainers
- Suction fittings
- Seals
- Drain or return tubes
Clogged strainers, damaged seals, air leaks or other intake-system problems can interfere with priming. These areas should be inspected as part of the applicable troubleshooting process before major components are replaced.
How Do I Find the Correct Graco Sprayer Part?
The most reliable method is to identify the component using your exact machine model and the official Graco part number, rather than selecting a part based on appearance.
- Identify the exact Graco sprayer.
- Record the machine part number and serial information when available.
- Locate the appropriate parts diagram or manual.
- Find the component on the exploded diagram.
- Record the manufacturer's part number.
- Check whether the original number has been replaced or superseded.
- Confirm compatibility before ordering.
This is particularly important because visually similar Graco sprayers can use different pumps, valves, filters, control boards and other service components.
Common Graco Sprayer Problems & Parts to Inspect
A symptom does not automatically prove that a specific component has failed. Use the table below as a starting point for inspection, then follow the service information for your exact machine.
| Sprayer Symptom | Components or Areas to Inspect |

| Spray tip clogs repeatedly | Filters, strainers, coating condition and spray tip |
| Poor spray pattern | Spray tip, filters, pressure setting and coating preparation |
| Fluid leaks around pump | Packings, seals and related fluid-section components |
| Gun spits or does not shut off correctly | Gun components, gun filter and applicable needle/seat components |
| Hose leaks or shows damage | High-pressure hose and fittings; discontinue use if damaged |
| Electric sprayer does not operate normally | Power supply and model-specific motor/control system following the service manual |
