A Silicone O-ring is a type of seal that is made from a silicone elastomer material. O-rings are designed to provide a tight, leak-proof seal between two separate parts, either stationary or moving. They are commonly used in a variety of industries, including automotive, aerospace, medical, and food and beverage, due to their excellent temperature resistance, chemical resistance, and low compression set. Silicone O-rings are particularly useful in high-temperature applications where other types of o-rings may not be suitable. They are also resistant to UV light and ozone, making them ideal for outdoor applications. Silicone O-rings are available in a range of sizes, shapes, and colors, and can be customized to fit specific sealing needs.
