The hex adapter assembly consists of a Graphalloy bushing, standard wear washer, and flanged sleeve with hex adapter. Graphalloy works at temperatures from 400 to 1,000°F and has run-dry capabilities. It eliminates the need for lubrication and, therefore, doesn't contaminate equipment with oil or grease.
