Aftermarket GRACO® 245145 Pump Repair Kit – includes Carbide Ball, Ring, Teflon O-Ring, Seat & Gasket (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 735435

Comparable OEM Part Number: 245145

Description: Total Finishing’s part # 20-3014 is a direct-fit replacement for the GRACO® 245-145 sampling/dump valve kit, a critical component in airless spray systems that diverts material flow for pressure relief, testing, or system priming without shutting down the pump.

Spray equipment technicians and pump rebuild specialists rely on this kit to restore dump valve functionality when wear, contamination, or seal degradation affects system control. Professional painting contractors and rental equipment service staff depend on proper dump valve operation to maintain consistent spray pressure and protect equipment during startup sequences and pressure transitions.

Common reasons for replacement:

• Valve seals or packings harden or deteriorate, causing leakage or failure to hold pressure during dump cycles
• Check balls or internal seats accumulate dried material or sediment, preventing full closure or smooth material diversion
• O-rings crack or compress, allowing bypass flow that compromises pressure regulation during sampling or priming operations
• Spring tension weakens, reducing the valve’s ability to respond quickly to pressure changes or operator control commands

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