Whether you need silicone rubber or a fluoroelastomer material, we can fulfil and ship your order with accuracy and fast turnaround.
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.
Many aircraft manufacturers use this component as a seal in hydraulic systems for brakes.In addition, you may find it integrated into wing flaps and landing gear.
Most O-rings are made out of synthetic rubber that has been designed to withstand the high temperatures and extreme conditions of aerospace applications. This characteristic is the reason they are used in aircraft and even space shuttles.
Hydraulic rescue tools, which help release people trapped in vehicles after crashes, and medical devices such as IV and implant components also rely on this component to work.
Designed for hygiene-critical environments, they are typically made from special medical-grade rubber. This property enables them to be heat-resistant and chemical-resistant to prevent cracking, bacteria and toxicity.
