Cryogenic seals are commonly used, such as in liquefied natural gas (LNG) and low-temperature food processing. In low-temperature environments, some materials may not maintain their desired physical properties. Temperatures below -150 °C (123 K; -238 °F) are considered a sealing-materials breaking point. FJSEALS has professional design and development capabilities to manufacture seals that can function normally at -196 ℃. Additionally, our spring energized seals can meet your requirements for both environmental conditions and sealing performance.
