摘要： A method of manufacturing a spiral-wound PTFE gasket includes winding a laminated PTFE tape (300) around a shaft (305) that has an outer diameter that coincides with the gasket inner diameter to create a PTFE cylinder (315) having an outer diameter that coincides with the gasket outer diameter; sintering the PTFE cylinder (315); and removing a radial segment of the PTFE cylinder (315) to form the gasket (100), the radial segment having a thickness that coincides with the gasket thickness.
