Aftermarket GRACO® 25D190 Packing Set, piston T/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75570

Comparable OEM Part Number: 25D190

Description: Total Finishing's part # 20-3417 is a direct-fit replacement for the GRACO® 25D190 piston seal package set, engineered for pumps requiring TFE and polyurethane composite sealing elements. This kit delivers the precision sealing architecture that spray equipment technicians and pump rebuild specialists depend on when restoring worn fluid delivery systems to full operational integrity.

Piston seal packages are critical interfaces within airless pump assemblies, where they manage pressure cycling and fluid containment under demanding spray conditions. When these seals degrade, pump output suffers immediately—and so does job productivity for professional painting contractors and equipment service crews who operate the machines. The TFE/polyurethane material combination in this package provides the chemical resistance and wear durability necessary for extended service life across variable coating applications.

Common reasons for replacement:

• Reduced pump pressure or flow rate indicating seal face wear or material degradation
• Visible fluid leakage around the piston rod or external pump housing
• Erratic spray patterns or pressure fluctuations during jobsite operation
• Recurring loss of prime or slow recovery after idle periods

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