Seal structure for positioning between two members disposed for sliding relative movement includes a band component that is adapted to be carried by one member and that has a front surface for engagement with the other member and a backup component that is seated in slidable relation on a rear surface of the band component. A seal surface is defined between two pressure distribution regions formed in the front surface of the band component, and the backup component is located in general alignment with the seal surface and provides pressure compensation at the seal interface between the seal surface and the juxtaposed surface of the other member.
