Aftermarket GRACO® 25D191 Packing Set, piston T/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75573

Comparable OEM Part Number: 25D191

Description: Total Finishing's part # 20-3426 is a direct-fit replacement for the piston packing set used in GRACO® Xtreme 220 TFE/PE airless spray equipment. This sealed assembly maintains pressure integrity within the pump's piston chamber, allowing consistent fluid delivery across high-demand coating applications.

Pump rebuild specialists and spray equipment service technicians rely on piston packing sets to restore worn pumps to OEM performance standards. When a packing set degrades, system pressure drops and fluid begins to bypass internally, compromising spray pattern and application quality.

Common reasons for replacement:

• Pressure loss or inability to reach rated PSI during priming or spraying
• Fluid weeping around the piston rod or visible leakage from pump seals
• Inconsistent spray output or reduced flow rate during active application
• Excessive heat buildup in the pump housing, signaling internal friction from worn packings

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