The Bedford 20-2904 is a direct-fit replacement for Graco check valve O-ring kits, essential consumables for maintaining seal integrity in airless spray systems and fluid handling equipment. Pump rebuild technicians and spray equipment service staff rely on these kits to restore proper sealing function when check valves begin to leak or fail to hold pressure.

Check valve O-ring kits typically include a complete set of elastomer seals sized to fit the valve chamber, ensuring reliable one-way flow control and pressure retention during spray operations. Replacing worn or degraded O-rings restores the check valve's ability to prevent backflow and maintain system pressure stability.

Common reasons for replacement:

  • Check valve leaks or weeps fluid under pressure, indicating O-ring deterioration or loss of elasticity
  • Pressure drops during idle periods, suggesting the check valve is not sealing effectively
  • System will not prime or build pressure, often traced to a compromised check valve seal
  • O-rings show visible cracks, hardening, or permanent deformation during routine inspection

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