The Bedford 20-3434 is a direct-fit replacement for the Graco 25D-178 throat package set, a complete seal and packing assembly for Xtreme 250cc pump models. This kit equips spray equipment technicians and pump rebuild specialists with the TFE and polyethylene components required to restore proper throat sealing during major pump overhauls or routine maintenance intervals.

Professional painting contractors operating high-volume airless equipment rely on throat package sets to maintain consistent spray patterns and prevent fluid bypass during mid-job repairs. Rebuilding the throat section is a critical step in extending pump service life and ensuring reliable performance on multi-day jobsites.

Common reasons for replacement:

  • Fluid leakage around the pump throat area during spraying or idle periods
  • Worn or hardened seals causing reduced pump pressure and inconsistent spray output
  • Scheduled preventive replacement as part of annual pump rebuild protocols
  • Damaged packings discovered during pump disassembly for routine maintenance

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