Description
The Bedford 19-2628 is a compatible replacement for Graco parts 176-751 and 176751 — the lower packing nut-ultra used in Graco spray equipment. The packing nut threads down on the packing stack to set its compression — it is the adjustment that keeps the throat sealing as packings wear, and on many pumps it doubles as the reservoir for throat seal liquid. Compatible with Graco 190 ES (st-style), Graco 290 Easy, Graco 390 st, Graco 390 sts, Graco 395 st, Graco 450 st and other compatible equipment.
Common reasons for replacement:
- Stripped or galled threads from repeated adjustment
- Worn wrench flats after years of service
- Packing compression no longer holding between adjustments
- Renewed during a full pump repack
Manufactured to OEM-equivalent dimensions for proper fit and performance.
