Brush Research Mfg. 85B375 Helical Power Tube Brush Brass

Product Description

The BRUSH RESEARCH MFG. 85B375 is a helical-style power tube brush with brass fill designed for cleaning and deburring the interior surfaces of tubes, pipes, and bores. The single spiral configuration distributes contact evenly along the bore wall, making it effective for removing scale, deposits, light burrs, and surface contamination. The brush measures 1-1/4 inches in length with an overall assembly length of 4-1/2 inches. The shank is 0.14 inches in diameter, constructed from galvanized steel for corrosion resistance. Rated to 2000 RPM, this brush is sized for use with standard drill chucks and rotary tools. Plumbers, HVAC technicians, and pipe fitting professionals install this type of brush as part of routine tube prep and maintenance work.

This brush is suited for use in tube cleaning applications across residential and commercial plumbing, HVAC refrigerant line prep, and light industrial maintenance. The brass fill material is non-sparking and compatible with soft metals, copper tube, and similar bore surfaces where steel bristles would cause damage or contamination. It performs well in both hand-held rotary tools and bench-mounted drill press setups where precise bore cleaning is required before fitting, soldering, or brazing operations.

Installation Notes

This brush is installed by trade professionals including plumbers and HVAC technicians using standard rotary tools or drills.

Wear appropriate eye protection when operating rotating brush tools, as bristle fragments can be ejected during use.
