The Bedford 12-231 is a direct-fit replacement for the Graco 158491 nipple. It is a threaded nipple used to join two pipe or hose-end fittings of matching or adapted thread sizes in spray equipment fluid and air lines.

Common reasons this nipple is replaced:

  • Thread damage from cross-threading or over-torquing
  • Corrosion or pitting from aggressive coatings and solvents
  • Cracking at the hex shoulder under high working pressure
  • Routine replacement during scheduled plumbing or hose service

Service technicians install this part during routine maintenance and during diagnostic teardowns of Graco spray equipment when the listed failure modes appear.

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