Pro-source 05127 Brass Twisted Wire Bristle Brush 3x7/8 in

Product Description

The PRO-SOURCE 05127 is a single-spiral brass twisted wire bristle brush designed for cleaning, deburring, and surface preparation in tight bore and tube applications. The brush head measures 3 inches in length with a 7/8-inch diameter, and the overall assembly reaches 10 inches in total length. Wire filaments are drawn from brass at 0.008 inches in diameter, providing firm yet non-sparking scrubbing action. The galvanized steel shank measures 0.16 inches in diameter for secure chuck or collet mounting. HVAC technicians, plumbers, and pipefitters commonly reach for this style of brush when cleaning fittings, ports, and internal passages before assembly or inspection.

This brush fits standard drill chucks and is sized for bore and port cleaning tasks common in HVAC, plumbing, and light industrial maintenance. The single-spiral fill pattern distributes filament contact evenly around the bore wall, making it well suited for cleaning copper fittings, threaded ports, heat exchanger passages, and similar confined surfaces. It is sold individually and works with both hand-held and low-speed power tools.

Key Features

• Brass wire fill resists sparking and corrosion, safe for use on copper and soft metals
• Single-spiral configuration provides consistent, even bore contact
• 0.008-inch wire diameter delivers firm scrubbing without aggressive material removal
• Galvanized steel shank accepts standard drill chucks and collets
• 10-inch overall length provides reach into deeper passages and fittings

Compatibility

Designed as a general-purpose bore brush for use in drill chucks and collets accepting a 0.16-inch shank diameter, suitable for cleaning 7/8-inch diameter bores, ports, and fittings in HVAC and plumbing applications.

Installation Notes

This brush is intended for use by HVAC technicians, plumbers, and pipefitters performing cleaning and surface prep tasks. When using with a power drill, keep rotational speed low to avoid excessive filament wear or heat buildup. Always power down and isolate any system before inserting the brush into ports or passages on live equipment. Inspect the brush for bent or loose filaments before each use and replace if the fill is significantly worn.
