Aftermarket GRACO® 210539 Pump Repair Kit with Polyurethane Packings (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 631617

Comparable OEM Part Number: 210539

Description: Total Finishing's part # 20-1268 is a direct-fit replacement pump repair kit for the 55:1 King and 20:1 Bulldog airless sprayers, designed to restore worn pumps to factory performance standards. Spray equipment technicians and pump rebuild specialists rely on this kit to address component wear during routine maintenance or major overhauls on high-volume professional painting operations. The kit enables professional contractors to extend equipment life and minimize downtime by replacing degraded internal components that compromise pressure output and spray consistency.

Common reasons for replacement:

• Packings and seals harden or compress over time, causing pressure loss and fluid bypass
• Check valves fail to seat properly, resulting in inconsistent atomization and poor spray patterns
• O-rings and gaskets degrade due to exposure to solvents, coatings, and prolonged high-pressure cycles
• Worn pump components produce audible noise, vibration, or reduced prime during startup

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