The Story
The Bedford 20-3429 is a direct-fit replacement for the Graco Xtreme 250cc piston package set, a core component assembly used in professional spray equipment maintenance and pump rebuilds. This kit supplies spray equipment technicians, pump rebuild specialists, and professional painting contractors with the precision-engineered pistons and related sealing elements required to restore full pressure capacity and flow consistency in Xtreme 250cc pump systems.
Piston package sets like this one are frequently serviced during routine pump rebuilds when equipment operators notice performance degradation or when preventive maintenance schedules demand component renewal.
Common reasons for replacement:
- Piston wear or scoring that reduces pump displacement and system pressure output
- Worn or damaged seals and packings around piston rod assemblies causing internal leakage
- Loss of prime or inability to maintain consistent spray pressure during production runs
- Scheduled maintenance intervals specified by equipment operators or fleet service protocols
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
Replacement for: Graco 25D-144, Graco 25D144.
