The "U-TIGHTSEAL" is a metal 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. The shape is a ring with a circular cross-section, and the structure consists of an elastic core tightly wound in the center, covered by one or two layers of coating. 【Features】 - The outer coating is made of a ductile metal that is easy to work with, while the inner coating in the case of a two-layer design uses a relatively hard metal material. - It can be used in environments where the use of elastomeric O-rings and gaskets is restricted due to issues related to vacuum and ultra-high vacuum, accelerator facilities, nuclear applications, aerospace engineering, valves, etc., including temperature, corrosion, pressure, radiation, gas release, and durability requirements. - As it is produced domestically, stable supply is possible, and we can also discuss short delivery times of around 30 days.
