Both meet the implied condition: when the sealing contact pressure is greater than the pressure of the sealed medium, the sealing effect is maintained; When the sealing contact pressure is less than the pressure of the sealed medium, the gasket or O-ring is pushed open, and there are many leaks in the medium
Learn more >Flat gasket seal contains gasket, flange and bolt, constitute a chaotic statically indeterminate system; The seal contact pressure is provided by the deformation of the bolt. The contact pressure distribution of flat gasket operation is uniform. When the medium pressure is shaken and greater than the contact pressure, leakage may occur

The comparison of O-ring and gasket:
For the condition of constant pressure, both of them can be matched; But on variable working conditions, when the pressure rises, it is possible to exceed the size of the contact pressure of the gasket, and the dielectric top opening sealing gap leakage. O-ring finishing gasket.Learn more >
In application, gasket is only used for static seal, O-ring can be used for static seal, but also can be used for reciprocating linear motion of dynamic seal. In terms of planning, the traditional method of gasket sealing planning is not tight enough, and the new specification of flange gasket planning is in the process of test and research. O-ring planning only needs to be determined according to the trench scale, which is simple and reliable, convenient and useful. In fact, whether it is O-ring or gasket, the most important thing is suitable, can be better play its sealing effect.
