Parker O Ring
A torus/doughnut-shaped ring, usually molded from a resilient elastomer, used to seal fluids (liquids or gases). O-rings provide wide pressure, temperature, and tolerance range sealing. They are easy to service, require minimal space, are reusable, and cost-effective with gradual failure patterns.
Overview
The O-ring is a torus (doughnut) shaped ring. It is usually molded from a resilient elastomer. It is used to seal fluids (liquids or gases). It is one of the simplest and most reliable seals ever developed. The seal is created by mechanically deforming (squeezing) the O-ring cross-section between the gland surfaces.
Advantages
O-rings seal over a wide range of pressure, temperature and tolerance. They can be used in static or dynamic applications. They are easy to service and require minimal space. They are reusable, cost-effective, and exhibit gradual failure patterns rather than catastrophic failure.
