Pro-source 05012 Brass Twisted Wire Bristle Brush

Product Description

The PRO-SOURCE 05012 is a single-spiral brass twisted wire bristle brush designed for cleaning, deburring, and surface preparation in tight bores and passageways. The brush head measures 1.5 inches long with a 0.1875-inch diameter, and the overall assembly reaches 7 inches in length, providing extended reach into tubes, ports, and small-diameter fittings. Brass fill material resists corrosion and is safe for use on soft metals and non-ferrous surfaces without risk of contamination. The galvanized steel shank at 0.085 inches in diameter is compatible with standard drill chucks and rotary hand tools.

This brush is suited for trade professionals working in plumbing, HVAC, refrigeration, and general mechanical service. Common applications include cleaning valve seats, orifice ports, heat exchanger tubes, burner orifices, and threaded fittings where abrasive residue, scale, or flux buildup needs to be removed. The 0.003-inch wire diameter provides a fine, controlled cleaning action appropriate for precision cleaning tasks where aggressive abrasion would damage seating surfaces or threads.

Key Features

• Brass fill resists corrosion and is non-contaminating on copper, brass, and aluminum surfaces
• Single-spiral construction provides consistent, even bristle contact throughout the bore
• 7-inch overall length allows reach into deep ports and tube interiors
• 0.085-inch galvanized steel shank fits standard rotary tool and drill chuck collets
• 0.003-inch wire diameter delivers fine cleaning action without excessive material removal

Compatibility

Designed as an OEM-style replacement and general-use twisted wire brush for trade applications requiring a 0.1875-inch diameter bore brush with a standard shank-mount configuration.

Installation Notes

This brush is installed in a rotary hand tool or low-speed drill by inserting the galvanized steel shank into the tool chuck and tightening securely before operation. Always verify that the tool speed rating is appropriate for small-diameter wire brushes to prevent filament breakage or shank failure. Wear appropriate eye protection when using rotary wire brushes. Shut off and depressurize any system before inserting the brush into lines or ports.
