The "Yutaito Seal" is a metal O-ring shaped gasket that incorporates an elastic core (coil spring). Despite being made of metal, it exhibits properties similar to elastomers (rubber) due to its excellent compression and recovery characteristics. It can be used in various locations that require long-term continuous use and is economical. It can be applied in areas where the use of elastomer O-rings and gaskets is restricted due to issues such as vacuum and ultra-high vacuum, accelerator facilities, nuclear applications, aerospace engineering, valves, and requirements related to temperature, corrosion, pressure, radiation, gas release, and durability. 【Structure】 ■ The standard type has a circular cross-section and consists of an elastic core (coil spring) tightly wound in the center, covered by one or two layers of coating. ■ The outer coating (outer layer) is made of a familiar, ductile metal, while the inner coating (inner layer) in the case of two layers is made of a relatively hard metal. *For more details, please download the PDF or feel free to contact us.
