Comprehensive Overview of Graco 107161 Seal, Rod, Valve Pilot
The Graco 107161 Seal, Rod, Valve Pilot is a high-precision sealing component designed for the pilot-valve rod assemblies in Graco’s industrial and airless spray equipment. It ensures reliable operation by maintaining a tight seal around the rod interface, minimizing air and fluid leakage and supporting consistent valve actuation under high-duty conditions.
Key Features
- Precision rod-seal geometry provides robust sealing on the pilot-valve rod, preventing air or fluid leaks that can compromise performance.
- OEM-specified for Graco systems ensuring exact fit, correct material, and retention of factory tolerances.
- Durable elastomer construction (commonly Buna-N) designed to resist wear, cycling, and exposure to typical spray-equipment fluids and air/gas systems.
- Service-friendly design allowing straightforward replacement during valve maintenance, reducing downtime and restoring OEM function.

Installation & Maintenance Guidelines
- Depressurize and power-off the system before servicing the pilot valve to avoid injury or damage.
- Remove the old seal and thoroughly inspect the rod and bore for scoring, corrosion or wear before installing the new seal.
- Install the 107161 seal ensuring correct seating, no twisting, and that the rod moves freely without binding.
- During scheduled servicing, check for leaks, drifting pressure, or increased rod play which may indicate seal wear and need for replacement.
Frequently Asked Questions
This seal prevents unwanted air or fluid leakage around the pilot-valve rod, maintaining consistent actuation and pressure control in the valve assembly.
Check the equipment’s parts list or exploded view diagram. If it lists “Seal, Rod, Valve Pilot – 107161,” then this is the correct replacement component.
While the seal may physically fit other applications with the same dimensions, it is engineered to Graco’s material and performance specifications. Using non-specified seals may impact performance or void warranty.
Replace the seal whenever you find leakage around the pilot valve rod, increased rod play, or during scheduled maintenance to maintain system reliability.
By choosing the correct component — the Graco 107161 Seal, Rod, Valve Pilot — you ensure reliable pilot-valve performance, reduced downtime, and long-term stability of your Graco fluid-handling and spray equipment.
