Aftermarket GRACO® 25D177 Packing Set, throat T/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75531

Comparable OEM Part Number: 25D177

Description: Total Finishing's part # 20-3425 is a direct-fit replacement for the GRACO® 25D-177 throat packing set, engineered for the Xtreme 220cc TFE/PE airless sprayer. This packing assembly seals the pump shaft and prevents fluid leakage at the gland, maintaining system integrity during high-pressure operation. Pump rebuild specialists and spray equipment service technicians rely on quality throat packing sets to restore proper sealing performance when equipment has experienced shaft wear or packing degradation.

Common reasons for replacement:

• Visible fluid weeping or dripping around the pump shaft during operation
• Loss of prime or inability to maintain pressure due to internal leakage
• Worn or hardened packing material that no longer compresses effectively against the shaft
• Routine rebuild service on Xtreme 220cc equipment approaching normal maintenance intervals

Manufactured to OEM-equivalent dimensions for proper fit and performance.
