What is an O-ring
An O-ring is a circular rubber sealing ring with a round cross-section. It is designed to fit into a groove and create a seal between two surfaces. The main purpose of an O-ring is to stop liquids or gases from leaking while maintaining pressure inside the system. An O-ring is a circular rubber seal with a round cross-section designed to fit into a groove between two or more components. When compressed during assembly, it creates a reliable seal that prevents the leakage of liquids and gases.
Despite its simple design, an O-ring is one of the most effective sealing solutions used in machinery, hydraulic systems, pneumatic equipment, automobiles, pumps, valves, and industrial machinery. Modern industries depend on quality O-rings to ensure smooth operation, improve equipment efficiency, and reduce maintenance costs.
