- Made from durable 50A silicone, this product withstands extreme temperatures ranging from -40℉ (-40℃) to 392℉ (200℃). It offers excellent waterproofing, ozone resistance, and strong sealing capabilities, ensuring reliable insulation for various applications. - Size specifications: The outer diameter is specified alongside the wire diameter. The inner diameter can be calculated as follows: inner diameter = outer diameter - 2 x wire diameter. For example, with an outer diameter of 15mm, the inner diameter is 5mm, and the cross-sectional diameter is also 5mm. - Versatile applications include: - Gas compressors - Heat exchangers - Boilers - Filters - Blenders - Coffee machines - Plumbing systems - Doors and windows - Household electrical appliances - Electronic instruments - The silicone O-rings are designed in a round cross-section to create effective seals between cylindrical overlapping surfaces. These O-rings are commonly used in engines, flanges, valves, and various cylinders, providing an essential solution for preventing leaks and ensuring optimal performance in demanding environments.
