Leak Protection Seal Rings
Precision rings, inc. is a leading manufacturer of custom seal rings. All metallic rings, whether they are piston rings or seal rings, allow some amount of leakage. Seal rings provide better sealing capabilities than piston rings. As such, a seal ring is typically used in applications where leakage is critical. Types of seal rings include, but are not limited to, two piece and three piece ring assemblies. Piston rings are used when leakage is not as critical. When the ring is properly seated via a differential in pressure, flow across the ring is restricted but not eliminated.
