O-Rings are circular elastomeric rings with a round cross-section, typically made from materials such as rubber or silicone. They are designed to create a tight seal between two mating surfaces, preventing leakage of fluids or gases.

In the NATO Supply Group 53, which encompasses Hardware And Abrasives, O-Rings fall under the specific class of 5331. This class is dedicated to the categorization and identification of O-Rings within the NATO supply system.

O-Rings are widely used in a variety of industries, including automotive, aerospace, plumbing, and manufacturing. They are known for their versatility, durability, and ability to withstand high pressures and temperatures. O-Rings are commonly used in hydraulic and pneumatic systems, engines, pumps, valves, and other mechanical applications.
