Aftermarket GRACO® 25D165 Packing Set, piston Teflon (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75495

Comparable OEM Part Number: 25D165

Description: Total Finishing's part # 20-3441 is a direct-fit replacement for the piston package set designed for Xtreme 290cc TFE airless spray equipment. This complete kit restores the reciprocating motion and pressure dynamics essential to consistent paint delivery and atomization in high-volume coating applications.

Pump rebuild specialists and spray equipment technicians rely on this piston package set to restore performance in Xtreme 290cc TFE units that have experienced pressure loss, inconsistent flow, or reduced spraying efficiency. The kit addresses wear and degradation in the piston assembly, which directly impacts pump displacement and outlet pressure stability during extended contractor use.

Common reasons for replacement:

• Piston surfaces become scored or worn after extended pump cycles, causing pressure bleed-off and reduced spray consistency
• Reciprocating seal surfaces lose their seal integrity, allowing fluid bypass and lower system pressure output
• Piston package components fracture or deform under sustained high-pressure operation in demanding contractor environments
• Fluid contamination or abrasive particles embed in piston surfaces, triggering friction and premature wear progression

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