An O-ring is a doughnut-shaped sealing element, typically made from various elastomers like Nitrile, FKM, or Silicone. Its primary function is to block the passage of fluids or gases by creating a secure seal between two mating surfaces. When compressed in a gland, the O-ring's elastic material deforms to fill the gap, preventing leaks. Known for their simplicity, reliability, and cost-effectiveness, O-rings are fundamental components in countless applications. They are essential in hydraulic and pneumatic systems, plumbing, automotive engines, and various industrial machinery. Their effectiveness relies on proper material selection for compatibility with the operating fluid, temperature, and pressure conditions.
