Aftermarket GRACO® 235198 Bypass/Dump Valve Repair Kit (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 705594

Comparable OEM Part Number: 235198

Description: Total Finishing's part # 20-2078 is a direct-fit replacement for the drain valve kit used in GRACO® airless spray systems, where reliable fluid evacuation and system maintenance are essential during equipment servicing and seasonal storage.

Spray equipment technicians and rental equipment maintenance staff rely on drain valve kits to empty fluid lines, pump cavities, and fluid pathways without disassembly of major components. A functional drain valve reduces downtime during maintenance cycles and prevents fluid degradation or contamination buildup when equipment sits idle between jobs.

Common reasons for replacement:

• Valve seat corrosion or erosion from prolonged contact with solvents, thinners, or aggressive cleaning agents
• Stuck or sluggish valve operation caused by dried paint or coating residue blocking the valve opening
• Leaking around the valve body seals, resulting in slow drips or seepage during fluid drainage
• Loss of pressure-tight seal integrity, preventing complete system evacuation for storage or fluid changeover

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