Pro-source 05125 Twisted Wire Bristle Brush Steel 3 in

Product Description

The PRO-SOURCE 05125 is a single-spiral twisted wire bristle brush designed for cleaning, deburring, and surface prep in bores, tubes, ports, and similar confined passages. The brush head measures 3 inches in length with a 7/8-inch diameter, giving it a compact profile suited for tight internal surfaces. Wire diameter is 0.008 inches, providing aggressive scrubbing action while conforming to irregular surfaces. The 0.16-inch galvanized steel shank connects to a standard rotary tool, drill, or flex shaft. Overall length is 10 inches. Licensed tradespeople and maintenance techs in HVAC, plumbing, and industrial service use this type of brush for port cleaning, scale removal, and thread prep.

This brush fits applications where a short, small-diameter bore brush is needed. Common uses include cleaning refrigerant ports, pipe threads, valve seats, heat exchanger tubes, and conduit fittings. The single-spiral fill pattern delivers consistent contact across the bore wall. The galvanized steel shank resists corrosion in wet or chemically active environments, making it a practical choice for plumbing and HVAC service work where moisture and flux residue are common concerns.

Installation Notes

Secure the shank firmly in the tool chuck before operation and confirm the chuck is tightened to prevent slippage at speed. De-energize or isolate any system being serviced before introducing a rotary brush into ports, valves, or fittings. Wear appropriate eye protection, as wire bristles can shed under load. Inspect the brush for splayed or broken wires before each use and replace if fill integrity is compromised.
