G14-46 Common Rail Pipe Sealing Surface Grinding Tool

The G14-46 Common Rail Pipe Sealing Surface Grinding Tool is a critical maintenance instrument for diesel fuel technicians. High-pressure common rail systems rely on perfect metal-to-metal seals at the pressure limiting valve connection. Over time, these surfaces can suffer from erosion, pitting, or carbon buildup, leading to pressure drops and fuel leaks.

This tool provides a manual, high-precision way to restore the sealing seat directly on the rail without needing to replace the entire common rail assembly.
