Steel Trap™ is the preferred gasket when you need improved performance but require lower seating stresses. It offers the sealing properties of an encapsulated element in a compression seal, is blowout resistant, and reduces the risk of fire often caused by leaky gaskets.
Steel Trap is the ideal replacement for problem applications. It is available in standard and custom designs, including a unique self-locating design. It also offers the ability to target the location sealing element and tailor the gasket placement to the desired flange surface.
Chesterton Steel Trap Metal/ Graphite Gasket is manufactured with concentric, isolated convolutions in sheet stainless steel that trap pure graphite against the flange face. As the flange is tightened, the convolutions are progressively flattened, thus trapping the graphite sealing media. Not only is a highly effective seal effected against both faces of the flange, but the graphite is protected against oxidizing atmospheres and corrosives. Steel Trap gaskets can remain in place and will continue to seal effectively until removal is necessary for equipment servicing or repair.
These seals pay for themselves many times over in reduced maintenance and downtime. The unique, self-locating design allows the same size gasket to be used in the vast majority of flange pressure classes. This results in unmatched time savings in locating the right gasket, while reducing inventory and virtually eliminating the chance of incorrect gasket selection.
