Aftermarket GRACO® 245103 Drain Valve Assembly, large handle with cap nut on top (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 735309

Comparable OEM Part Number: 245103

Description: Total Finishing’s part # 20-3591 is a direct-fit replacement for the Spray Prime/Drain Valve Kit, a critical component in GRACO® airless spray equipment that manages fluid evacuation and system priming between jobs.

Spray equipment technicians and rental equipment maintenance staff rely on this valve assembly to maintain proper fluid control during equipment setup, shutdown, and storage cycles. A functional drain valve prevents residual material buildup, ensures clean system priming, and supports efficient equipment changeovers on job sites.

Common reasons for replacement:

• Valve seat degradation or internal corrosion causing slow or incomplete drainage
• Seal failure resulting in fluid leakage around the valve body during pressurized operation
• Spring tension loss preventing the valve from fully opening or closing
• Debris accumulation or dried material blocking proper valve operation

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