Aftermarket GRACO® 245525 Pump Repair Kit with Leather & Polyethylene Packings (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 736575

Comparable OEM Part Number: 245525

Description: Total Finishing's part # 20-2781 is a direct-fit replacement for the GRACO® 245525 pump repair kit designed for 1900 series sprayers. This comprehensive kit is essential for spray equipment technicians and pump rebuild specialists performing full-service maintenance and component restoration on these widely-used airless units.

Pump repair kits for the 1900 sprayer consolidate all wear-prone internal components into a single, coordinated package—seals, packings, check balls, and O-rings—ensuring that related parts are replaced together to restore consistent pressure performance and spray output. Professional painting contractors relying on 1900 equipment during active job schedules depend on quick, reliable kit-based rebuilds to minimize downtime.

Common reasons for replacement:

• Pressure fluctuations, loss of atomization, or inconsistent spray pattern indicating internal seal degradation
• Fluid leakage from pump housing seams or rod passages, pointing to failed packings or O-ring seals
• Reduced flow rate or difficulty priming after extended operation, suggesting accumulated wear in critical seal areas
• Contamination or scoring of internal pump surfaces requiring full component replacement as part of preventive maintenance

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