Graco Pump Packing Repair Kit (18B260)
When a sprayer starts leaking at the throat, losing pressure, or pulsing instead of holding a steady stream, worn pump packings are usually the reason. This genuine Graco kit replaces the throat and piston packings, O-rings, and seals that wear out with regular use, restoring the seal without replacing the whole pump.
Fits
390, Ultra 395, Ultra Max II 490, 495, and 595, FinishPro and FinishPro II 390/395/595, ST Pro and STX, LineLazer, and FieldLazer. This kit is the direct replacement for the older part number 244194. Check your sprayer's model and parts manual to confirm fit before ordering, since Graco makes different packing kits for other pump sizes.
Signs it's time to rebuild
- Paint leaking at the throat or wet cup
- Loss of pressure or trouble holding pressure
- Pulsing or an uneven spray pattern
- Slow or difficult priming
Why genuine parts
Genuine Graco parts keep the correct material compatibility with the coatings your pump was designed for. A packing rebuild is routine maintenance on a sprayer that sees regular use, and keeping a kit on the shelf means a short repair instead of a day waiting on parts.
