Graphite seal / metal - -200 - 900 °C | Steel Trap™
Manufactured by Chesterton, this Steel Trap metal/graphite gasket has concentric and isolated convolutions made from sheet stainless steel. They are used to trap pure graphite against the flange face. The graphite sealing media is trapped because the flange is tightened so as to gradually flatten the convolutions. This results in protection of the graphite against oxidizing corrosive agents and atmospheres, as well as a highly effective seal against both faces of the flange. The gaskets can stay in place, providing effective seals until it is necessary to remove them for equipment repair or servicing. Due to the reduced downtime and maintenance, the seals repay their cost several times over. In addition, the same size of gasket is useful in most flange pressure classes because of its unique, self-locating design. This provides multiple advantages, such as the inventory is reduced, the prospect of incorrect gasket selection is practically eliminated, and it provides tremendous time savings in locating the correct gasket.
