The Bedford 19-391 is a compatible replacement for Graco parts 100103 and 100-103, a cotter pin for Graco spray equipment. A cotter pin is the small split pin that locks a castle nut or clevis in place so vibration cannot back it off. Cotter pins are single-use hardware: once the legs have been spread and bent back straight, the pin should be replaced, not reused. Compatible with Graco 13:1 Senator (HydraCat), 20:1 Bulldog (HydraCat), 45:1 King (HydraCat), Double Wall Hopper Feed Pump, GH 733 (Hydra-Spray), Monark 5:1 and other Graco equipment.

Common reasons for replacement:

  • Missing pin letting a nut or clevis work loose
  • Pin discarded during teardown — they are single-use hardware
  • Fatigued or cracked legs from repeated bending
  • Corrosion after exposure to coatings and solvents

Manufactured to OEM-equivalent dimensions for proper fit and performance.
