Pro-source 04980 Twisted Wire Bristle Brush Brass

Product Description

The PRO-SOURCE 04980 is a miniature twisted wire bristle brush designed for precision cleaning, deburring, and surface preparation in tight spaces. The brush features a brass fill material wound in a single spiral pattern around a stainless steel shank. With a brush diameter of 0.031 inches and a brush length of 0.5 inches, this tool reaches into small bores, ports, and passages where larger brushes cannot fit. The 0.003-inch wire diameter provides firm yet controlled abrasion, making it well-suited for removing light contamination, flux residue, and oxidation from small fittings, tubing ends, and threaded openings.

This brush is used in plumbing, HVAC, and general mechanical maintenance applications where precision cleaning of small-diameter passages is required. Typical uses include prepping copper fittings prior to soldering, cleaning valve seats and orifice ports, and clearing debris from threaded fittings on refrigerant or fuel lines. The 4-inch overall length gives the technician adequate hand clearance while working in confined areas. The 0.025-inch stainless steel shank is compatible with standard rotary tool chucks and flex-shaft handpieces.

Key Features

• Brass fill material resists corrosion and is safe for use on copper and brass fittings without scratching soft base metals
• Single spiral construction provides consistent bristle density and uniform contact along the full brush length
• 0.031-inch brush diameter accesses small bores, ports, and orifices not reachable with standard brushes
• 4-inch overall length provides hand clearance in confined installation spaces
• 0.025-inch stainless steel shank fits standard rotary tools and flex-shaft handpieces
• 0.003-inch wire diameter delivers controlled abrasion suitable for light cleaning and flux removal

Compatibility

Designed as a precision rotary-use twisted wire brush for small-bore cleaning and surface preparation tasks common in HVAC, plumbing, and mechanical maintenance applications. Shank diameter of 0.025 inches fits standard rotary tool chucks and flex-shaft handpieces that accept that shank size.

Installation Notes

Installed and used by HVAC technicians, plumbers, and mechanical maintenance professionals. When using with a rotary tool, confirm the chuck is fully tightened on the stainless steel shank before operating to prevent slippage. Always wear appropriate eye protection when operating rotary wire brushes. Inspect the brush for bent or loose wires before each use and replace if bristle integrity is compromised.
