The Story
The Bedford 20-3658 is a direct-fit replacement for the Intake Seat O-Ring Kit (Graco 16W-484), a critical sealing assembly in the fluid intake pathway of airless spray systems. This kit restores the seal integrity at the intake seat, where incoming fluid enters the pump chamber during the intake stroke. Pump service technicians and spray equipment specialists rely on this kit to eliminate fluid leakage, restore priming efficiency, and prevent air infiltration that degrades spray quality.
Common reasons for replacement:
- Fluid seepage around the intake seat, indicating worn or hardened elastomer seals from prolonged exposure to solvents or coating materials
- Loss of prime or difficulty achieving vacuum during the intake cycle due to compromised seal surfaces
- Visible deterioration of O-ring material during pump inspection or routine rebuild procedures
- Pressure fluctuations or inconsistent spray patterns caused by air entry through a failing intake seal
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 16W-484, Graco 16W484.
