Aftermarket GRACO® 25D163 Packing Set, piston Teflon (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75489

Comparable OEM Part Number: 25D163

Description: Total Finishing's part # 20-3423 is a direct-fit replacement for the GRACO® 25D163 piston packing set, engineered for the Xtreme 220 TFE airless sprayer. This packing set maintains the dynamic seal between the pump's piston rod and cylinder, preventing fluid leakage while sustaining consistent pressure delivery during high-volume coating applications.

Pump rebuild specialists and spray equipment service technicians rely on this component to restore performance in Xtreme 220 TFE units that have experienced degraded pressure retention or visible fluid weeping around the piston rod. The TFE (polytetrafluoroethylene) formulation provides superior chemical resistance and wear characteristics compared to standard packings, extending service intervals in demanding professional environments.

Common reasons for replacement:

• Fluid leakage or weeping around the piston rod during pressurized operation
• Loss of system pressure despite proper valve and seal integrity elsewhere in the pump
• Visible scoring or wear marks on the piston rod surface after extended use
• Recurring pressure drops following routine equipment maintenance or seasonal startup

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