Explosive Decompression (ED) O-rings are seals used in high-pressure systems where a sudden decrease in pressure can cause gases or fluids to expand rapidly, leading to damage to equipment and endangering personnel. Explosive Decompression O-rings are designed to resist the effects of explosive decompression, providing a reliable and safe sealing solution in high-pressure applications.

ED O-rings are made from materials that are highly resistant to gas permeation, such as perfluoroelastomers (FFKM) and hydrogenated nitrile butadiene rubber (HNBR). These materials have a low gas permeation rate, which means they can resist the effects of gas expansion during ED.

FFKM materials are highly resistant to chemicals and high temperatures, making them suitable for use in harsh environments. They can withstand temperatures ranging from -10°C to 325°C and have excellent resistance to explosive decompression.

HNBR materials are known for their high tensile strength, wear resistance, and durability. They have a temperature range of -40°C to 150°C, making them suitable for use in a wide range of applications.

ED O-rings are commonly used in the oil and gas industry, as well as in aerospace and other high-pressure applications. In the oil and gas industry, they are used in various applications, including downhole drilling equipment, wellhead connectors, and high-pressure pumps. In aerospace, ED O-rings are used in applications such as rocket motors, fuel tanks, and hydraulic systems.
