Aftermarket GRACO® 25D237 Pump Repair Kit with Leather & Polyethylene Packings (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75711

Comparable OEM Part Number: 25D237

Description: Total Finishing's part # 20-3427 is a direct-fit replacement for the GRACO® 25D-237 pump repair kit designed for the Xtreme 250cc - L/PE airless sprayer. This comprehensive kit equips spray equipment technicians, pump rebuild specialists, and professional painting contractors with the packings, seals, and internal components needed to restore worn or damaged pumps to OEM performance standards.

The Xtreme 250cc - L/PE is widely deployed on job sites requiring high-volume coating output, making reliable pump function essential to contractor schedules and equipment uptime. When rebuild components wear or fail, a complete kit approach minimizes downtime by addressing multiple wear surfaces in one service interval.

Common reasons for replacement:

• Pressure seals and packings deteriorate from abrasive fluid contact and cyclic compression, leading to internal leakage and loss of spray pressure
• Check balls and seats accumulate coating residue or mechanical wear, reducing pump efficiency and causing weak or stuttering spray patterns
• O-rings and gaskets harden or crack from exposure to solvents and UV, allowing air ingestion or fluid bypass around pump chambers
• Worn rod seals permit fluid weeping around the connecting rod, contaminating the motor area and reducing overall pump reliability

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