Frequently Asked Questions

Check your sprayer’s parts manual for the exact fluid-section/pump number. If it lists 239922 (or an alternate like 246429), you’re good to go. Model names alone can vary by generation.

Hard or no priming, pressure drop when the gun is released, or fluid leak-back at the inlet side usually indicate a worn seat/ball or damaged O-ring.

Basic hand tools and cleanliness usually suffice. Follow torque and assembly order in your manual. Always clean the seat cavity before reassembly.

No—this is the inlet (intake) seat kit. Outlet/discharge seat kits are different part numbers. Use the manual to avoid mix-ups.

Some revisions reference 246429 as an updated or alternate kit. If your manual lists 246429, order that part number. For older manuals listing 239922, this kit is the intended match.
