o-ring design

The face seal design chart below explains the hardware dimensions to use for an O-ring seal when the groove is cut into a flat surface.
Systems Which Contain Internal Pressure
For designing systems which contain internal pressure, like the example below, the groove's outside diameter (OD) is primary, and the groove's width then determines the inside diameter.

Technology is always moving forward, but some things stand the test of time.
One of those things is the O-Ring, which was first patented in 1896. 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.
