Abstract
A C-shaped seals is used under severe conditions in which rubber gasket and o-ring can not be used. Furthermore, C-seals exhibit various advantage such as small fitting space and light weight, therefore widely used as sealing elements for rocket engines and automotive engines. And also particular advantage offered by C-seals is good springback, high level of sealing performance under high pressure condition, stretching of the flange bolts.
This paper is concerned of the sealing mechanism of C-seal by experimental work and finite element stress analysis. As a result, the lead coated layer on a C-seal has an important function on the sealing performance. In the present paper we describe on an interesting results reached by experiments regarding correlation of helium leakage late and contact pressure.
