Pro-source 05145 Twisted Wire Bristle Brush 3x1 Inch Steel

Product Description

The PRO-SOURCE 05145 is a single-spiral twisted wire bristle brush designed for tube cleaning, deburring, and surface preparation in tight bores and passages. The brush head measures 3 inches in length with a 1-inch diameter, and the overall assembly reaches 10 inches in total length, giving technicians extended reach into pipes, heat exchanger tubes, and conduit ends. Steel fill wire at 0.008 inches in diameter provides firm scrubbing action without excessive flex. The 0.16-inch galvanized steel shank mounts directly into a drill chuck or hand driver, making it a standard tool for HVAC techs, plumbers, and pipefitters during pipe prep and maintenance work.

This brush is suited for residential and light commercial applications where tube interiors, fittings, or bore surfaces need to be cleaned, deburred, or prepared before soldering, brazing, or inspection. Common install scenarios include cleaning copper pipe ends before flux and solder, clearing scale from heat exchanger passages, and prepping conduit or fitting interiors. The single-spiral configuration moves debris out of the bore efficiently in a single pass. It is a standard shop and field tool kept in the service vehicle for day-to-day pipe and tube work.

Installation Notes

This brush is installed and used by HVAC technicians, plumbers, and pipefitters as part of routine pipe and tube preparation. Secure the shank firmly in the drill chuck before operation and confirm the chuck key is removed before powering the drill. When used on pressurized systems, depressurize and isolate the line segment before inserting the brush. Wear appropriate eye protection, as wire bristles can shed during aggressive use.
