Product Overview

The Graco 16H932 Packing O-Ring is a factory replacement sealing component designed to maintain leak-free performance inside fluid passages. It is used in assemblies where a precise O-ring fit is required to maintain proper pressure and seal integrity.

Over time, packing components wear due to pressure cycles and material fatigue, making timely replacement important for maintaining sprayer performance and preventing fluid leaks.
