Abstract
An improved gasket with scavenging capabilities for sealing two relatively stiff mating pieces of an enclosure. The gasket comprises a flexible compressible gasket member shaped to fit between the mating pieces. The gasket member comprises a porous material configured so as to pass only a small amount of ambient atmosphere therethrough. The porous material is infiltrated with a scavenging compound for removing pollutants from the ambient atmosphere passing through the porous material. The gasket has particular application in instrumentality sensitive to pollutants, such as magnetic disc drive devices. Such a disc drive is also disclosed.
