The Bedford 20-5331 is a direct-fit replacement for the Graco 25D140 piston seal repair kit for Xtreme and XP Xtreme 115cc lowers, supplying the piston glands and leather and UHMWPE v-packings that seal the piston against the cylinder wall.

The leather and UHMWPE combination is the abrasion package for high-solids and filled coatings. Piston packing wear shows up as a rising cycle rate at unchanged output, since the pump has to work harder each stroke to move the same volume.

Common reasons for replacement:

  • Pump cycling faster than normal to hold the same spray pressure
  • Pressure bleeding off under a closed gun rather than holding
  • Uneven delivery between the upstroke and the downstroke
  • Hardened, glazed or worn leather packings found when the cylinder is opened

Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
