Bushing

A threaded bushing commonly provides a transition between connection sizes or forms, but the generic identity does not establish the exact reducing relationship or end arrangement. Actual products may use different body styles, so hex or flush construction, outer and inner thread arrangement, and reduction direction must not be inferred from the name. Selection should define both interface sizes and types, body form, size transition, sealing method, tool-engagement clearance, thread engagement, and possible flow-path effects. Thread standard, material, coating, and operating conditions must be confirmed from actual product documentation and the project specification.
