Rubber O-Rings & Kits
What Is an O-Ring?
An O-ring is a rubber sealing component with a circular cross-section. It is named after its distinctive "O" shape and is one of the most widely used sealing elements worldwide.
Installed between two mating components, an O-ring creates a reliable seal through proper compression, effectively preventing the leakage of liquids, gases, oils, and other media while keeping dust, moisture, and contaminants from entering the equipment.
Thanks to its simple design, low cost, and excellent sealing performance, O-rings are widely used in a broad range of industrial equipment and mechanical systems.
How Does an O-Ring Work?
When installed in a groove and compressed, an O-ring generates elastic restoring force that allows it to fit tightly against the sealing surfaces, creating a reliable seal.
As system pressure increases, the pressure further forces the O-ring against the sealing surface, enhancing the sealing effect. This enables O-rings to provide reliable sealing performance in both low-pressure and high-pressure applications.
