System and Method for Connecting a Compression-Type Coupling to a Coated Conduit

Abstract

A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.
