Simple sealing element used predominantly for static sealing.
A PTFE o-ring is an endless round ring that has a circular cross section and is predominantly used as an axial static seal. By pressing the cross section during installation, the sealing effect comes into play. Since PTFE has a negligible elastic behavior, an expanding slot has been incorporated around the circumference. This side has to permanently face the pressure side.
PTFE o-rings are always used when the general elastomer o-ring cannot withstand the needed resistance for thermal or chemical applications. Due to good chemical resistance, physiological harmlessness and sterilizability, PTFE o-rings are widely used in the chemical industry, petrochemistry as well as in the medicine and food industry.
