It is virtually impossible to find an o-ring that is made from natural rubber - the stuff that comes from rubber trees - today. What you will find instead is a product that is made out of a synthetic material, called an elastomer, that looks, feels and behaves like one might think natural rubber would.
An O-ring is a solid-rubber seal shaped like a doughnut or torus. When compressed between mating surfaces, an O-ring blocks the passage of liquids or gases. Parco O-rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications. Two dimensions describe the size of an O-ring: its inside diameter (ID) and its cross-sectional diameter (CS) (see Figure 1). Understanding O-ring Sizes and Tolerances Standard Sizes The standard sizes used by Parco and the other major O-ring manufacturers in the United States are defined by Aerospace Standard AS568B, Aerospace Size Standard for O-rings. That document, published by the Society of Automotive Engineers (SAE), lists the sizes of
