The brush features a 0.375 inch diameter with steel wire filaments measuring 0.004 inches in diameter, delivering consistent scrubbing action along internal surfaces. With an overall length of 8 inches and a shank diameter of 0.132 inches, it mounts readily into standard rotary tools, drills, or flex-shaft machines.

This tube brush is used in residential and commercial applications wherever internal tube or bore cleaning is required. Typical use cases include cleaning heat exchanger tubes, copper pipe ends, condenser and evaporator tube sheets, and small-diameter bores before soldering or mechanical joining. The steel fill material makes it effective on ferrous and non-ferrous metals alike. It is sold individually and is well suited for service technicians who need a compact, reliable brush for field or shop use.
