Project details

O-shaped rubber sealing ring is a type of rubber ring with a circular cross-section, which is the most widely used sealing element in hydraulic and pneumatic systems. It is a bidirectional sealing element that can provide sufficient sealing preload under initial radial or axial compression. The following is its working principle:

Under no pressure, the O-ring rubber seal remains in its original shape.

When an external force is applied to it, it will deform on the contact surface with the groove and generate a certain amount of pressure.

When the pressure continues to increase, the O-ring rubber seal will undergo greater deformation and further enhance the sealing effect.

When the pressure is unloaded, the O-ring rubber seal will return to its original shape.

Its characteristics include the following:

Small size, easy to assemble and disassemble.

Both dynamic and static seals are available.

The static seal has almost no leakage.

Single piece uses bidirectional sealing.

Low dynamic friction.

The price is low.

In short, the O-ring rubber seal is a reliable sealing element that can be used in various occasions. For more information, it is recommended to consult a professional.
