Aftermarket GRACO® 25D145 Packing Set, piston L/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75435

Comparable OEM Part Number: 25D145

Description: Total Finishing's part # 20-3438 is a direct-fit replacement for the piston package set in GRACO® Xtreme 290cc L/PE airless sprayers. This complete assembly is essential for pump displacement and pressure generation, making it a critical component for maintaining reliable spray output on high-performance coating equipment.

Spray equipment technicians and professional contractors rely on piston package sets to restore pump efficiency after extended use or wear. This kit addresses the core moving components that handle repeated pressurization cycles, ensuring consistent fluid delivery across residential, commercial, and industrial coating applications.

Common reasons for replacement:

• Visible scoring or wear marks on piston surfaces reducing seal integrity and causing pressure loss
• Loss of spray pressure or inconsistent output indicating piston-to-barrel wear exceeding service limits
• Fluid leakage from pump body seams suggesting worn piston packings cannot maintain proper sealing
• Reduced pump capacity or slower spray delivery requiring full piston package renewal rather than partial repairs

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