Spiral Wound Gaskets are extremely popular and widely used. A spiral Wound Gasket is manufactured by spirally winding a preformed metal strip and a filler on the outer periphery of metal the inner diameter of the Gasket and superposed metal and nonmetallic windings are continually wound until the required outer diameter is attained. This engineered product is tailor made to be compatible with the flange closure in which it is to be used.

They are more resilient than any other type of metallic Gasket with the exception of pressure sealing metal Gaskets and, as a consequence, can compensate for flange movement that may occur due to temperature gradients, variations of pressure and vibration.

They can be used over the complete temperature range from cryogenic to approximately 20000 degrees Fahrenheit. This type of Gasket can be used in all pressures form vacuum to the standard 2500 PSI flange ratings.
