An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section, from which the "O" in its name is derived. O-rings function as compact and reliable sealing devices by absorbing the tolerance stack-up between closely mated surfaces in both dynamic (moving) static (stationary) applications.
An oring seals by blocking any potential leak path of a fluid (liquid or gas) between two closely spaced surfaces. The oring is generally installed in a machined groove
in one of the surfaces to be sealed. As the two surfaces are brought together, forming a gland
, they squeeze the cross section on the oring.
