Claim 1:
2. A gasket interposed between flanges which are connection parts between pipes, the gasket comprising:
a kammprofile having sawteeth on an upper surface and a lower surface thereof;
a first C-ring end having an opening and a self-energizing function and formed at an inner side of the kammprofile to be integrally formed with the kammprofile;
a first core spring having a circular shape and assisting the self-energizing function of the first C-ring end and accommodated in the first C-ring end;
a second C-ring end having an opening and a self-energizing function and formed at an outer side of the kammprofile to be integrally formed with the kammprofile;
a second core spring assisting the self-energizing function of the second C-ring end and accommodated in the second C-ring end;
a stopper formed on at least a part of the upper surface and the lower surface of the kammprofile,
wherein the stopper is a flat plane extending horizontally from a point on the kammprofile which is lower than peaks of the sawteeth and higher than valleys of the sawteeth;
a first eyelet disposed on an outer surface of the first C-ring end, covering the first C-ring end and blocking the opening of the first C-ring end; and
a second eyelet disposed on an outer surface of the second C-ring end, covering the second C-ring end and blocking the opening of the second C-ring end,
wherein the first eyelet covers a whole outer side surface of the first C-ring end such that the first C-ring end and the first core spring are protected from outside of the gasket; and
wherein the second eyelet covers a whole outer side surface of the second C-ring end such that the second C-ring end and the second core spring are protected from outside of the gasket.
