Pro-source 05002 Brass Twisted Wire Bristle Brush

Product Description

The PRO-SOURCE 05002 is a brass twisted wire bristle brush designed for cleaning small-diameter bores, tubes, ports, and threaded fittings common in HVAC, plumbing, and light mechanical work. The brush head measures 1 inch in length with a 0.125-inch diameter, and the overall assembly reaches 6 inches in total length. Wire filaments are drawn to 0.003 inches for firm yet controlled scrubbing action. The single-spiral fill pattern distributes brass bristles evenly around the tip, making this brush well suited for deburring, surface prep, and flux or residue removal in confined passages. Technicians in HVAC and plumbing trades reach for this style of brush when cleaning small pipe ports, valve seats, and refrigerant or gas line fittings before assembly or brazing.

This brush fits standard rotary tool chucks and hand-held pin vises with a 0.085-inch galvanized steel shank. It is commonly used in residential and light commercial settings during pipe fitting, valve service, coil cleaning, and pre-solder or pre-braze surface preparation. The brass fill material is non-sparking and will not contaminate copper or brass fittings, making it appropriate for gas and refrigerant line work where ferrous contamination is a concern.

Key Features

• Brass bristles resist corrosion and are safe for use on copper, brass, and soft alloy surfaces
• Single-spiral fill pattern provides uniform bristle distribution across the 1-inch brush head
• 0.003-inch wire diameter delivers firm scrubbing without scoring soft fitting surfaces
• 0.085-inch galvanized steel shank fits standard rotary tool chucks and pin vises
• 6-inch overall length provides reach into ports and bores while keeping hands clear of work
• Non-sparking brass fill suitable for gas line and refrigerant fitting prep work

Compatibility

Designed for use with rotary tools and hand-held pin vises accepting a 0.085-inch round shank. Suitable for cleaning small-diameter bores, ports, and fittings in HVAC, plumbing, and general mechanical applications.

Installation Notes

Secure the shank fully into the tool chuck before operating to prevent slippage or wobble during use. When used for pre-braze or pre-solder surface prep on gas or refrigerant lines, ensure the system is fully de-pressurized and isolated before beginning any mechanical cleaning. Use appropriate eye protection when operating rotary-driven wire brushes. Follow applicable IFGC and local mechanical codes for surface preparation requirements on gas piping connections.
