Description
The Bedford 0-139 is a direct-fit replacement for the Graco 156633 o-ring used on Graco airless spray equipment. It maintains a fluid-tight seal at the installed location under operating pressure.
Common reasons this o-ring is replaced:
- Fluid leaking at the seal during operation
- Pressure loss or pump cavitation from a bypass at the worn seal
- Visible cracking, swelling, or deformation of the o-ring
- Scheduled seal replacement during pump or filter 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.
