Description
The Bedford 0-4187 is a direct-fit replacement for the Graco 117283 throat o-ring used on Graco airless pumps. It seals the piston throat against high-pressure fluid bypass.
Common reasons this throat o-ring is replaced:
- Fluid bypassing the piston past a worn throat o-ring
- Pressure loss or stalling pump from a leaking throat seal
- Visible compression set or extrusion at the throat seal groove
- Scheduled throat seal replacement during pump rebuild
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
