Manufacturer: Total Finishing Supplies

Part Number: 53070

Comparable OEM Part Number: 17K690

Description: Total Finishing’s part # 20-4211 is a direct-fit replacement pump repair kit for GRACO® 390, 395, 490, 495, 595, and 695 series sprayers, as well as Gmax 3400 units. This comprehensive kit is designed for spray equipment technicians, pump rebuild specialists, and professional painting contractors who service high-volume airless systems in the field.

Pump repair kits for these GRACO® models typically contain packings, seals, O-rings, check balls, and other internal wear components necessary to restore hydraulic function and pressure integrity after extended use or maintenance cycles. Having the correct kit on hand allows technicians to complete full pump rebuilds without ordering individual components separately, reducing downtime for rental fleets, service shops, and contractor operations.

Common reasons for replacement:

• Pressure fluctuations, loss of spray pattern consistency, or inability to maintain rated PSI during active application
• Fluid leakage from pump housing seams, shaft seals, or connection ports indicating internal seal degradation
• Reduced flow rate or weak spray output despite engine operation at full throttle
• Cavitation noise, sputtering discharge, or visible fluid aeration in the spray line suggesting internal component wear

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