What are O-rings?

An O-ring, which may also be known under other names like toric joints, is a specific type of mechanical gasket. As the name suggests, an O-ring is formed in an O or donut-like shape, technically known as a torus. Made from simple polymers, O-rings are used for forming seals between parts. They can have many applications and are some of the cheapest, easiest-to-make, and most reliable seals used in industrial applications today.

What are O-rings Used for?

The main function of O-rings is to form a seal between two joining parts. The O-ring is placed between the parts, acting as a sealing connector and helping to stop leaks and losses of gas or liquid, while also forming a layer of protection against debris. Different types and materials of O-rings may be used to seal components against various liquids and gases, and O-rings can handle high levels of pressure without breaking or bursting.

The Best O-rings

When using any kind of seal or gasket, including O-rings, it’s important to use good quality parts that won’t let you down. A good O-ring should be able to reliably keep your components and machines safe, while poor quality products can break or fail. At Motion, you’ll find nothing but the very best O-rings for sale from leading brands.
