MS28774 - SPLIT TEFLON® O-RING BACK UP - INCH

These spiral 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 spiral design allows for ease of installation. These parts do not meet mil spec testing requirements. Prices can be quoted for mil spec applications requiring additional testing and certification.
