Advantages & Disadvantages of Standardizing O-Rings

When the O-Ring concept was originally developed, there was no standardization of sizes. Product designers and manufacturers would design O-ring seals specifically for their applications and machinery, meaning O-Ring suppliers would only produce specific sizes they had customers for. Very few sizes, if any, were used by more than one customer and this lack of standardization discouraged O-Ring manufacturers from producing in the most economical quantities.

How To Measure An O-Ring?

O-rings come in different shapes and sizes. Knowing the measurements an application needs can make a difference on how well an O-ring works. If the O-ring is too big for the application, it will not seal properly. If the O-ring is too small for the application, the seal might break. The performance of an O-ring seal can be optimized by choosing the most appropriate size, which can be found by measuring an O-ring.

What Is An O-Ring? History and Applications of O-Rings

Most mechanical systems require seals. These devices help join mechanisms together by preventing leakage and are crucial to the functionality of machinery. A gasket is a type of seal that is compressed in the area between two or more surfaces. O-Rings (also known as packing joints) are donut-shaped gaskets that can be used in static or dynamic applications. O-Rings are easily manufactured, inexpensive, and dependable; making them one of the most common seals used in machinery across the globe.
