Spiral Wound Gaskets
Construction: Special Spring like Metal strips are wound with an Asbestos Filler by a special process to assure a leak proof seal. The sealing is done by the Asbestos Filler and the metal strip provides the spring. This combination of metal and soft asbestos Filler piles compresses to its predetermined thickness under bolting pressure and thereby preventing leakage within the limit of its specified pressure and temperature ranges. With the addition of Centering devices, adapt  Spiral Wound Gaskets to use on many types of flanges and closures.

Materials: Standard materials are type 304 Stainless steel with white Canadian (Chrysotlie) Asbestos Filler
