Rubber O-Rings & Kits
O-rings are circular rubber sealing components installed in grooves. When compressed, they deform to fill gaps between mating surfaces and prevent liquid or gas leakage. They are suitable for both static and dynamic sealing applications and are widely used in hydraulic systems, pneumatic equipment, automotive parts, and industrial machinery.
YMI offers standard and custom O-rings in various materials, hardness levels, sizes, and colors. Custom mold development is available based on customer drawings, dimensions, or samples.

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.
