Basic Concepts of O-Ring Seal Covers

An O-Ring Seal Cover is a type of gasket that uses an O-ring—a toroidal piece of elastomer with a round cross-section—to create a seal. This seal is achieved by the O-ring being compressed between two or more mating surfaces. In mechanical systems, O-Ring Seal Covers play a role in preventing the leakage of fluids and gases, thereby maintaining the integrity of the system. They are commonly used in applications where dynamic sealing is required, such as in rotating or reciprocating machinery ¹.
