ID-5.625 Nominal CS-1/4" 70 Duro NBR Standard O-Ring Inch

These solid TFE backup rings are machined from virgin TFE to military drawings and are popular in commercial applications requiring low friction, fluid compatibility or high temperature. The solid design is easier to install in larger bore sizes as there are no ends to catch. These parts do not meet mil spec testing requirements. Prices can be quoted for military applications requiring additional testing and certification.

An O-ring is a mechanical gasket in the shape of a torus or donut; it is a loop of elastomer or other material with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
