Titan part 106-005 is an upper packing spring designed to maintain proper tension on the upper packings inside the displacement pump. This spring ensures a reliable seal between the piston and cylinder, preventing fluid bypass, pressure loss, and leakage. Replacing a worn, broken, or collapsed spring restores pump efficiency, consistent output pressure, and extends the life of the packing assembly.

The Titan 106-005 Upper Packing Spring is a precision component that applies consistent upward pressure against the upper packings inside the pump cylinder. This tension keeps the packings properly expanded against the piston and cylinder wall, creating a tight seal that prevents fluid from bypassing the piston.
Over time, the spring can lose its tension, become distorted, or break entirely due to fatigue, chemical exposure, or debris. A failed spring leads to pressure loss, erratic spray performance, pump stall, or fluid leaking into the lower pump section. Replacing the upper packing spring restores proper seal compression and ensures reliable, consistent output.
| Maintains seal pressure | Keeps packings expanded to prevent fluid bypass |
|---|---|
| Supports consistent output | Helps maintain steady pressure and flow |
| Prevents packing extrusion | Proper tension reduces wear on packings |
| Loss of pressure | Pump cannot maintain rated output pressure |
|---|---|
| Fluid leakage | Material seeps past packings or into lower pump |
| Broken / collapsed spring | Visible damage or spring no longer provides tension |
| During packing replacement | Preventive replacement to ensure long seal life |

When replacing the upper packing spring, inspect or replace these associated components to ensure a complete, reliable pump repair.
Replace the upper packings at the same time if they show wear or if the spring failed due to packing extrusion.
Fluid leaking past the upper packing spring may indicate lower packings also need service.
Inspect the piston rod for scoring or corrosion that could damage the new spring and packings.
