Fluorine rubber O-rings are available in various types, each with distinct properties based on their molecular structure and fluorine content. These differences affect their chemical resistance and low-temperature performance. Known for their self-extinguishing nature, fluororubber offers excellent airtightness—capable of maintaining a vacuum as low as 1.33×10â»â· to 1.33×10â»â¸ Pa. It also exhibits strong resistance to ozone, weathering, and aging, making it highly durable in harsh environments.
In addition to its flame resistance, fluororubber is widely used in high-performance applications due to its exceptional sealing capabilities. It can operate effectively at temperatures up to 250°C, making it ideal for use in automotive and aircraft engine systems. It is particularly well-suited for sealing bearings in engine power units, as well as for engine stem seals, cylinder liner seals, and clutch seals. Other common applications include air filter seals, fuel pump seals, and the inner linings of fuel hoses.
Fluororubber O-rings are commonly used in a wide range of industries, including electronics, automotive components, hydraulic systems, oil pumps, sanitary equipment, bearings, antenna waterproofing, and lighters. They provide reliable sealing performance in environments that require electrical insulation, oil resistance, and resistance to non-polar solvents. These materials are compatible with aliphatic hydrocarbons such as propane, hexane, mineral oils, and fuels, as well as vegetable and animal oils, silicone oils, greases, fire extinguishing agents, and diluted acid-base salt solutions.
Whether in industrial machinery or everyday consumer products, fluororubber continues to prove its value through its versatility, durability, and ability to perform under extreme conditions. Its unique combination of properties makes it a preferred choice for critical sealing applications where reliability and longevity are essential.
Manhole Cover
A manhole cover is a removable plate that is used to cover the opening of a manhole, which is a hole in the ground that provides access to underground utility lines, such as sewer, water, or electrical systems. Manhole covers are typically made of cast iron or other durable materials to withstand heavy loads and prevent unauthorized access to the underground infrastructure. They are usually round in shape to prevent them from falling into the hole and are designed to be easily lifted and replaced by maintenance workers when necessary. Manhole covers are an essential component of urban infrastructure, ensuring the safety and functionality of underground utility systems.
