The Bedford 20-1726 is a direct-fit replacement packing set for the 45:1 King, GH733, and 13:1 Senator airless spray pumps. This assembly contains the elastomer packings and seals required to maintain pressure integrity and prevent fluid leakage at the pump rod interface—a critical maintenance component for pump rebuild specialists and spray equipment service technicians.

Packing sets wear under normal operation as the reciprocating pump rod cycles through thousands of strokes. When packings degrade, system pressure drops, spray pattern quality suffers, and fluid seepage occurs around the rod. Rebuilding with genuine OEM-equivalent packings restores the pump to factory performance specifications and extends equipment service life.

Common reasons for replacement:

• Visible fluid weeping or spray around the pump rod during operation
• Loss of system pressure or inconsistent spray output without apparent hose or nozzle obstruction
• Difficulty achieving target pressure settings that previously worked reliably
• Degraded or hardened packing material visible during pump inspection or seal cartridge removal

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