Spiral Wound Gaskets are the most used semi-metallic Gaskets for high pressure joints. Depending on the flange type and application, a wide variety of configurations of the Spiral Wound Gasket can be used.
Metal Jacketed Gaskets, as the name suggests, consist of a metallic outer shell with either a metallic or nonmetallic compressed fiber filler. The filler material gives the gasket resilience while the metal jacket protects the filler and resists pressures, temperatures and corrosion.
In order to overcome some of the setbacks of the solid polymerized Teflon, gaskets have been produced to take advantage of the resilience of asbestos, rubber and other like materials.
