ABSTRACT:
The present invention is an improved gasket for use in a wide variety of sealing applications. The gasket comprises a sheet of expanded polytetrafluoroethylene (PTFE) that is helically wrapped around itself and sealed in that orientation. This construction produces a gasket that has significant tensile strength in both its longitudinal and transverse axes. As such, the gasket of the present invention retains all of the operational advantages of PTFE while being quite resistant to creep.
