Aftermarket GRACO® 25D192 Packing Set, piston T/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75429

Comparable OEM Part Number: 25D192

Description: Total Finishing's part # 20-3435 is a direct-fit replacement for the GRACO® Xtreme 250cc piston package set with TFE and polyethylene components. This kit supports the full piston assembly rebuild for high-volume airless spray systems, enabling spray equipment technicians and pump rebuild specialists to restore worn or damaged pump internals without replacing the entire pump unit.

Xtreme 250cc pumps are workhorses in professional painting operations and rental equipment fleets, where reliable pressure and flow are essential. This piston package set contains the precision-engineered components needed to restore original performance and pressure consistency. Professional painting contractors depend on these pumps for day-in, day-out production spraying, making timely piston maintenance critical to job continuity.

Common reasons for replacement:

• Piston ring wear or scoring caused by abrasive fluid circulation and repetitive stroke cycles
• Seal degradation from extended run time, reducing pump pressure and increasing internal bypass
• Polyethylene component brittleness or cracking from thermal cycling or age
• Loss of pump prime or inconsistent pressure output indicating internal seal failure

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