Silicone o ring is a mechanical gasket in the shape of a torus. Silicone o ring is a loop of elastomer with a disc-shaped cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. Silicone o ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the silicone o ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
Silicone o rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. A silicone o ring is a round ring that is used as a gasket for sealing a connection. Silicone o rings are commonly used in mechanical applications, such as pipe connections, and help to ensure a tight seal between two objects. Once in its track, the silicone o ring is compressed between the two pieces and, in turn, creates a strong seal where they meet. The seal that a silicone o ring creates can either exist in a motionless joint, such as between piping, or a movable joint, such as a hydraulic cylinder. However, movable joints often require that the silicone o ring be lubricated. In a moving enclosure this ensures slower deterioration of the O-ring and therefore, extends the useful life of the product. Silicone o rings are made of silicone. Silicones are inert, synthetic compounds with a variety of forms and uses. Typically heat-resistant and rubber-like, they are used in sealants, adhesives, lubricants, medical applications, cookware, and insulation. Silicones are polymers that include silicon together with carbon, hydrogen, oxygen, etc.
