This O-ring is crafted from red silicone rubber, featuring a round cross-section and a durometer rating of 50A, making it an excellent choice for applications requiring flexibility, weather resistance, and high/low temperature performance.
Silicone rubber provides outstanding resistance to extreme temperatures, operating effectively from -65°F (-54°C) to 400°F (204°C) while maintaining flexibility and resilience. It also offers excellent resistance to ozone, sunlight, and weathering, making it ideal for outdoor and aerospace applications. Silicone is generally compatible with water, many alcohols, dilute acids, and certain oils, but is not recommended for use with concentrated acids, fuels, aromatic hydrocarbons, or steam under pressure.
With a shore durometer of 50A, this silicone O-ring indicates a specific hardness level and its resistance to permanent indentation. A higher durometer value reflects greater resistance to indentation, with the scale ranging from 0 to 100, where 100 means no indentation occurs.
O-rings are typically employed to create pressure and fluid seals between overlapping cylindrical surfaces. They are commonly found in applications such as food processing equipment, medical devices, automotive components, aerospace systems, and outdoor enclosures. Shaped like a doughnut, these circular rings feature a hole in the center. O-rings come in various sizes and can be ordered based on the required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter.
These silicone O-rings conform to the standards set by Aerospace Standard AS568A, which defines the Aerospace Size Standard for O-rings.
Nominal Dimensions: These are the stated or labeled dimensions of a material but do not necessarily represent its true size. They are often rounded for convenience.
Actual Dimensions: These are the real, measured sizes of the material, which can be slightly smaller or larger due to manufacturing tolerances.
