50Helical alloy spring energized seals for medical device
The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material. Working in the temperature range from -196℃ to 121 ℃, suitable for complicated chemicals.
Spring seals are popular in the medical device industry for many reasons, because of their low friction, chemical resistance, and excellent performance under various pressures, temperatures and speeds. Spring actuated PTFE seals provide a reliable sealing solution that is effective even in low pressure environments. Even if JST's existing energized PTFE seals cannot meet your needs, you can customize and design appropriate energized PTFE seals according to requirements and specifications.
JST provide customers with various types of spring energized seal products, which have been widely used in occasions with high requirements for durability, chemical resistance and work at extreme temperatures. They are widely recognized in the LNG industry, oil production, petrochemical, compressor, semiconductor, hydraulic equipment, and medical equipment industries.
