O-rings function as a means of sealing, essentially closing off a passageway to prevent the escape or loss of a fluid, either a liquid or a gas. An O-ring has a toric shape, and is typically manufactured from an elastomeric material. The seal is established by placing the O-ring into a cavity, known as a gland. The gland acts to compress the O-ring, and produces a zero-clearance condition, which effectively blocks the flow of the fluid. The sealing effect is produced through axial or radial compression of the O-ring.

In general, O-ring seals are considered to be particularly reliable due to the simplicity of the O-ring/gland design and overall material resilience. However, under a number of circumstances failure can occur. O-ring failure can range from minor leakage to catastrophic equipment breakdown. Regardless of the magnitude, an O-ring failure can be diagnosed through proper visual and analytical techniques.

This webinar will review:

  • O-ring Function
  • Failure Modes
  • Sealing System Design Factors
  • O-ring Materials – Selection and Specification
