O-ring because of its low manufacturing cost and easy to use, which is widely used in a variety of dynamic and static sealing occasions. O type sealing ring sealing mechanism: O-ring is an automatic two-way sealing element. The pre-compression of its radial and axial aspects during installation gives the O-ring its own initial sealing capability. It increases with the increase of system pressure.

O type sealing ring sealing mechanism:
O-ring is an automatic two-way sealing element. The initial sealing capability of the O-ring itself is given by the pre-compression of its radial and axial aspects during installation. It increases with the increase of system pressure. Kan
Factors to consider when choosing an O-ring:
1. Seal Form
According to the load type, it can be divided into static seal and dynamic seal; according to the sealing purpose, it can be divided into hole seal, shaft seal and rotating shaft seal; according to its installation form, it can be divided into radial installation and axial installation. For radial installation, for shaft seals, the deviation between the inner diameter of the O-ring and the diameter d2 to be sealed should be as small as possible; for hole seals, the inner diameter should be equal to or slightly less than the diameter d1 of the groove.
2, working medium and working conditions.
In the specific selection of O-ring material, we must first consider the compatibility with the working medium. The working conditions such as pressure, temperature, continuous working time and operation cycle of the seal shall also be comprehensively considered.
