O-rings are a type of mechanical gasket and are one of the most common types of seals used in machines due to their cost effectiveness, high durability, simple manufacturing process, and easy installation into machines.

O-rings can be used with a large variety of pressure, temperature, and tolerance ranges. Due to their durability, small size, and cost effectiveness, it’s no surprise why O-rings remain dominant in the sealing space.

O-rings offer a plethora of advantages when it comes to many different types of applications. Not only are they are cheap, simple to install and able to withstand a large amount of wear and tear over time, provided that they are maintained properly. Due to how adaptable they are, they prevent leakage.

For example, hydraulic cylinders move very quickly and put a large amount of pressure on their seals. The simple o-ring can handle it. O-rings can function properly in many types of mobile or immobile joints and piping. They are also present in many other types of equipment that wouldn’t first seem obvious, like laptops and computer mice. They are, by and far, the most dominant type of seal.

And that’s just the O-ring, I didn’t even start talking about when you may want to consider using an o-seal. A tale for another time.

You can read even more about O-rings and their various applications with Gallagher’s O-Ring design guide. A 36 page resource which details their technical performance, materials, compatibility, hardware, failure modes, and more. It’s worth the read if you’re interested in better understanding the technical application and usage of O-rings.

Such a simple, but yet critical component for so many industries. In the future, advancements like rubber nano-tech have the potential to take some of the market share away from the O-ring, but for now it remains in its throne.
