Graco 245413 Pump Cylinder — Overview & Fitment
Compatible Machines
The Graco 245413 Pump Cylinder fits the fluid section on the following Graco units (always verify your unit’s series number in the manual before ordering):
- GMAX 7900 gas airless sprayers (select series)
- GH 200 gas hydraulic sprayers (select series)
- LineLazer 200HS line stripers (1-gun / 2-gun; IV/V generations as applicable)
What is the 245413 Pump Cylinder?
The 245413 is the fluid-section pump cylinder—the precision-bored sleeve where material is pressurized in Graco displacement pumps. Replacing a worn or scored cylinder restores sealing and pressure, reducing pulsation and improving spray quality.
- Direct replacement for the fluid section on compatible pumps
- Helps recover pressure, prime, and finish consistency
- More economical than replacing a full pump assembly

Fitment Notes
- Confirm your unit’s model and series (e.g., GMAX 7900, GH 200, LineLazer 200HS) against the parts list in your manual.
- If your pump lower has been upgraded or replaced previously, match by pump assembly number (e.g., 246257, 248971) instead of the sprayer family alone.
- Inspect piston/packings/ball seats during service; replacing the cylinder without addressing other worn components may not restore full performance.
Frequently Asked Questions
Check the parts list in your machine’s manual. If your lower assembly/pump group is listed as 246257 or 248971 (or fluid pump groups like 277068, 24W995), the 245413 Pump Cylinder is typically the correct fluid-section cylinder. When in doubt, match by pump assembly number and series.
It’s smart to inspect/replace packings, seals, and check-valve components during cylinder service. If your piston or seat shows wear, add the corresponding repair kit to ensure a complete, long-lasting fix.
Persistent loss of pressure, difficulty maintaining prime, pulsation at the gun, and visible scoring/pitting on the cylinder surface usually indicate replacement is needed.
After reassembly, prime with the appropriate solvent, check for leaks, and run at low pressure to ensure smooth cycling. Follow your manual’s torque specs and safety procedures during reassembly and testing.
Replacing a worn cylinder restores pump efficiency, but overall finish also depends on tip size, hose/filter cleanliness, material viscosity, and the condition of packings and check valves.
Service & Safety Notes
- Depressurize the system fully and follow all lock-out procedures before service.
- Use proper tools; avoid sharp tools that can damage the sleeve or sealing surfaces.
- Lubricate per manual, torque to spec, and perform a leak/pressure test after reassembly.
