The Story
The Bedford 20-3677 is a direct-fit replacement for the Graco Dura-Flo 1100 leather repair kit, engineered to restore pump performance in high-volume fluid handling systems used by professional painting contractors and pump rebuild specialists.
This kit contains the leather packings and seals required to revive a worn Dura-Flo 1100 pump, restoring pressure capability and eliminating fluid bypass that occurs during extended service life. Spray equipment technicians rely on kits like this to extend equipment uptime on active job sites without requiring full pump replacement.
Common reasons for replacement:
- Leather packings compressed or hardened from age, reducing pump pressure and output
- Fluid seepage past the piston rod indicating seal degradation
- Inconsistent spray pattern caused by internal packing wear
- Pressure loss under load after extended operating hours
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 237166, Graco 237-166.
