Aftermarket GRACO® 288818 Pump Repair Kit & Plunger (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 866454

Comparable OEM Part Number: 288818

Description: Total Finishing’s part # 20-3696 is a direct-fit replacement for the repair kit for GRACO® ProX7, X9, and SR7 pumps, designed for professional technicians who service high-volume airless sprayers. This kit contains the internal components needed to restore worn or damaged pumps to original operating condition, making it essential for pump rebuild specialists and spray equipment service shops that maintain professional-grade coating equipment. 

Pump repair kits like this one are stocked by equipment technicians, rental service centers, and contractors who operate their own maintenance programs. Rather than replacing an entire pump assembly, field technicians can restore pump performance quickly and cost-effectively by installing fresh internal packings, seals, and wear components.

Common reasons for replacement:

• Pump output pressure drops or becomes inconsistent during spray application, indicating packing wear or seal degradation
• Fluid leaks from pump rod or backstroke rod seal areas, requiring internal component replacement
• Pump performance deteriorates after extended use or seasonal storage without proper fluid flushing
• Routine preventive maintenance on heavily used spray equipment to avoid unscheduled downtime

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