Piston Rings » Piston Rings

Piston Rings are typically tempered to have an outward or inward tension to seal against the bore or cylinder of a device. Typical examples of where industrial piston rings are used are in valves, down hole tools, sealing one-time inserted devices, and in some higher dynamic applications like reciprocating piston compressors. Piston rings can also be engineered to provide a seal with better overal capabilities than a typical industrial piston ring. Seal Rings are used in applications where leakage is critical.
