Claim:
1. A method of manufacturing a gasket having a gasket thickness, a gasket inner diameter, and a gasket outer diameter, the method comprising: winding a PTFE laminate tape around a shaft that has an outer diameter that coincides with the gasket inner diameter to create a PTFE cylinder having an outer diameter that coincides with the gasket outer diameter, wherein the PTFE laminate tape includes a filler; winding a polymer tape around the shaft, the polymer tape being less porous than the PTFE laminate tape; sintering the PTFE cylinder; and removing a radial segment of the PTFE cylinder to form the gasket, the radial segment having a thickness that coincides with the gasket thickness.
