A comprehensive technical analysis of O-rings!

O-rings, rubber rings with a circular interface shape, play a crucial sealing role in the fields of hydraulics and pneumatics and are regarded as the most widely used sealing components. Its unique bidirectional sealing design enables the O-ring to be endowed with a strong initial sealing capacity through the initial compression in the radial or axial direction during installation. As the system pressure increases, the force acting on the O-ring will also increase accordingly, thus ensuring that its total sealing force continuously strengthens as the system pressure rises.

When subjected to pressure, the shape of the O-ring is quite similar to that of a liquid with high surface tension, presenting a characteristic of uniform deformation. This deformation enables the pressure to be evenly transmitted in all directions, thus ensuring its excellent sealing effect.
