What is an O-Ring?
It`s a doughnut-shaped loop designed to prevent the passage of liquids or gases. It`s one of the simplest precision mechanical pieces ever produced, and continue to be one of the most widely-utilized sealing products.O-Rings can be made from plastic or metal, but for the purposes of our blog, we`ll focus solely on rubber – or elastomeric - O-Ring design. An O-Ring, also known as a [torus," works in tandem with the glands in which they are installed. The gland is normally cut from the metallic hardware, and works with the O-Ring to seal. The gland and the O-Ring must be designed together to insure top performance.
How does an O-Ring seal?
Seals prevent fluids from escaping through the gaps in mating pieces of hardware. The O-Ring sits in the middle of a gland when it`s at rest, but as pressure begins to rise in the sealing system, the O-Ring shifts to the opposite side of the pressure.Because the material is soft, the O-Ring is mechanically squeezed to plug the hole between the two mating hardware pieces.Limitations of O-Ring use[Although it has been stated that O-Rings offer a reasonable approach to the ideal hydraulic seal, they should not be considered an immediate solution to all sealing problems."
Pearl wrote those words almost 70 years ago, but distinct limitations remain for using O-Rings as a primary seal. These limitations include:
*Rotary speeds above 1,500 feet per minute
*Improper mating hardware design
*Incompatible temperature, pressure and fluid chemical compatibility
