  Spiral Wound Gaskets Spirals are used in very high pressure applications or in very corrosive or high temperature environments such as pipelines in the chemical and petroleum industries. Construction of the sealing part of the gasket is a strip of high grade metal, commonly stainless steel, wound in a spiral (known as the winding).

  Gasket Construction. The spiral wound gasket is semi-metallic, comprising of a spirally wound v shaped stainless steel strip and a non-metallic filler material, such as graphite or PTFE. Also on the gasket, is a solid outer ring used for centering and controlling compression. This minimizes the risk of material creep through over-tightening.
