Inquire About This Product
basic information
We deliver O-rings that utilize synthetic rubber tailored for various applications, capable of withstanding long-term use and harsh conditions. The shape of the O-ring is fundamentally determined by two dimensions: the "thickness" (outer diameter) of the circular cross-section of the O-ring and the "inner diameter" of the O-ring loop. It is used to be installed between two components, like an outer tube and an inner tube, to prevent the ingress and egress of fluids. By creating a groove and making its depth smaller than the thickness of the O-ring, the O-ring is compressed. This generates a restoring force between the O-ring and the two components, allowing them to be tightly sealed together. This is the fundamental sealing principle of the O-ring.
