Rubber O-Ring Temperature Ranges

O-Ring Compound Materials are a type of elastomeric material used to make O-Rings. It is a rubber-like material that is designed to provide a seal against liquids, gases, and other materials. O-Ring Compound Material is designed to provide superior temperature and chemical resistance and is available in a variety of compounds designed to meet the requirements of a wide range of applications. They are often used in the automotive, aerospace, and medical industries, as well as in other areas where a reliable seal is required.-Ring Compound Material is able to withstand a wide range of temperatures, from -80°F to 617°F, making them an ideal choice for use in extreme environments.
