Aftermarket GRACO® 176751 Lower Jam Nut, piston (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 530253

Comparable OEM Part Number: 176751

Description: Total Finishing's part # 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.
