Pro-source 05055 Twisted Wire Bristle Brush Steel Fill

Product Description

The PRO-SOURCE 05055 is a twisted wire bristle brush designed for cleaning small bores, tubes, and tight-access passages. The brush head measures 2 inches in length with a 7/16-inch diameter, carried on a single-spiral configuration that maintains consistent contact with bore walls during rotation. Wire filaments are 0.006 inches in diameter, providing firm but controlled scrubbing action. The galvanized steel shank measures 0.11 inches in diameter and extends the overall assembly to 8 inches, giving the technician reach into deep cavities without secondary extensions. HVAC technicians, plumbers, and maintenance mechanics use this brush for deburring, cleaning, and surface prep in confined passages.

This brush is suited for residential and light commercial maintenance tasks where small-diameter bore cleaning is required. Common applications include cleaning heat exchanger tubes, condensate drain ports, small pipe fittings, threaded connections, and valve seats. The 8-inch overall length allows access through panels and tight enclosures without full disassembly. The single-spiral fill pattern makes it well-suited for rotary use with a hand drill or manual chuck tool.

Installation Notes

This brush is installed and used by HVAC technicians, plumbers, and general maintenance mechanics. Before cleaning any bore or passage in an active system, shut off power or isolate the line and relieve any pressure in accordance with applicable safety procedures. When using with a rotary tool or drill, secure the shank fully in the chuck before operating. Inspect filaments for wear or breakage before each use and replace the brush if wires are missing or the spiral is deformed.
