  • the core spring can be easily fixed and attached without an outer jacket through the sealing end formed at one side of the camp profile. Therefore, there is an effect that can provide a gasket to reduce the production cost through this simple structure. In addition, the restoring force of the gasket can also be improved at the same time.
  • the load of the fastening bolt can be concentrated in the mo part of the tooth member even under the underbody negative pressure through the tooth members formed on the upper and lower surfaces of the camp profile. Therefore, there is an effect that can provide a tight sealing.
  • the sealing end is formed on both sides of the camp profile has the effect of further improving the restoring force and sealing of the gasket.
  • the eyelet surrounding the sealing end of the camp profile has an effect of reducing the turbulence caused by the fluid by blocking the direct contact of the fluid flowing through the tube with the internal components of the gasket.
  • the sealing profile covering the gasket at the center with the highest gasket mounting surface pressure is provided with a camping profile including a central portion that is more convex upward and downward than both ends of the camp profile. Digging more firmly in between can increase the sealing effect.
  • gasket of the present invention has the following effects.
  • the core spring can be easily fixed and attached without an outer jacket through the sealing end formed at one side of the camp profile.
