RUBASIA RUBBERTECH’s rubber O-ring, also called a sealing ring, is a circular, donut-shaped component made of a flexible material like rubber (elastomer) that creates a seal to prevent leaks of liquids or gases. O-rings work by being compressed in a groove between two mating parts, deforming to fill the gap and block unwanted leakage in both static (stationary) and dynamic (moving) applications. They are a simple, reliable, and cost-effective sealing solution used in a vast range of machinery and systems. 

 

Key features of O-rings 

• Shape: O-rings have a circular cross-section, like a donut.
• Function: They seal gaps between mechanical components to prevent leaks.
• Mechanism: When installed, they are compressed and deform to create a tight seal.
• Material: While they are often made of rubber (elastomers), they can also be made from materials like PTFE or metal.
• Applications: They are used in a wide variety of industries, including hydraulic and pneumatic systems, automotive engines, and aerospace components.
• Types: O-rings are classified by their application:
  • Static: Used for sealing between two surfaces that do not move.
  • Dynamic: Used for sealing between surfaces that move, such as a piston in a cylinder. 

 

Why they are widely used 

• Cost-effective: They are cheap to produce.
• Simple: They are easy to fit and require simple, inexpensive grooves to be manufactured.
• Reliable: They can reliably hold high-pressure fluid or gas.
