All You Need to Know About O-Rings

 First introduced at the start of the 20th century, O-rings are exceptionally simple and basic, yet still a very critical component of our industrial systems today.

We all know that the unprecedented technological advancements have completely transformed the engineering, design, and manufacturing worlds, what may surprise you is that O-Rings are still used and designed the same way as they were a hundred years back!

Howsoever, some elements used in the O-ring manufacture have evolved they’re fundamentally simple and hence a reliable solution for industrial problems.

So, How Does an O-Ring Work?  

Whether you purchase O-rings individually or wholesale, they’re all the same. O-rings offer a leak-proof seal between the two components you want to keep separate from each other, As their name suggests, O-rings are spherical; just like classic doughnuts, and help in preventing the unwanted flow or escape of gasses or liquids.

They’re also regarded as a specified type of gaskets; what makes them different, however, is that they can be used in extreme pressures where an average cork, rubber gasket, or paper may fail or stop working.

Fundamentally, the O-ring seals rest on a channel or a groove between two components that are generally pushed together. Typically, O-rings are made out of elastomer, at the junction between the two parts and compress themselves to provide a tight and reliable seal system.

The amount of internal pressure applied to this junction directly affects how much the O-ring will be distorted inside its channel; thus improving the total sealing force. However, there’s always a certain limit up to which you can apply pressure, otherwise, it may lead to seal failure. You need to keep up the right balance between the O-ring material, working environment, and size.

Common Uses

Mechanical seals are critical for maintaining pump efficiency, energy consumption reliability, and emission control. O-rings are most commonly used in pumps, cylinders, connectors, or valves. The seal sits at the joining point of two different components. These components may be pneumatic, hydraulic, static, or dynamic.
