ring seal
Loop-shaped sealing component
A ring seal is a circular gasket—typically rubber, metal, or plastic—that fits into a groove to create a watertight or airtight connection between two surfaces.
O-rings are the most common type.
Ring seals appear in plumbing, hydraulics, and engine components: The leak was caused by a worn ring seal.
Separately, a ring seal is an Arctic seal species with distinctive circular markings on its coat.
