Ground Balls are precision-engineered sealing elements used in static sealing applications where spherical geometry is required. Made from high-performance elastomers or polymers, these ground balls ensure tight, leak-proof sealing under pressure and temperature variations. Commonly used in valves and check systems, they offer excellent chemical resistance, durability, and long service life in demanding industrial environments.
