What is an O-ring?
This mechanical gasket is formed of a loop with a round cross-section which would usually sit in an indentation. It would then be compressed between two or more parts at time of assembly.
The ring will return to its natural shape once the cross section is compressed to create an effective seal.
This component is also known as a 'toric joint' owing to its shape or an elastomeric O-ring seal based upon its function. It is both reliable and easy to use and is a frequently purchased part from our product portfolio.
Though it can be used for static applications, this important rubber part has the ability to seal a good amount of pressure. This makes it the ideal choice for dynamic applications with swivelling joints such as hydraulic cylinder pistons.
