Pro-source 05137 Brass Twisted Wire Bristle Brush 3x15/16 in

Product Description

The PRO-SOURCE 05137 is a single-spiral brass twisted wire bristle brush designed for cleaning, deburring, and surface preparation in tight bores, tubes, and threaded fittings. The brush head measures 3 inches long with a 15/16-inch diameter, and the overall assembly reaches 10 inches in total length. Brass fill wire at 0.008 inches diameter provides firm yet non-sparking bristle action suited for use on copper, brass, and other softer metals. The 0.16-inch galvanized steel shank is sized for standard drill chucks and rotary hand tools, making setup fast in most shop or field environments.

This brush is commonly used by plumbers, HVAC technicians, and pipefitters for internal cleaning of pipe ends, fittings, and valve seats before soldering, brazing, or threading. The single-spiral construction channels debris out of the bore while maintaining consistent bristle contact along the full brush length. It is equally suited to bench work and on-site service calls where a compact, machine-driven cleaning tool is needed.

Key Features

• Brass fill wire resists corrosion and will not spark against copper or brass surfaces
• Single-spiral pattern promotes debris evacuation during rotary use
• 3-inch brush length with 15/16-inch diameter fits common pipe and fitting bores
• 0.16-inch galvanized steel shank fits standard drill chucks and rotary tool collets
• 10-inch overall length provides reach into deeper bores without an extension
• 0.008-inch wire diameter delivers firm bristle action without aggressive material removal

Compatibility

Designed as a general-purpose twisted wire bristle brush for use with standard rotary tools and drill chucks accepting a 0.16-inch round shank.

Installation Notes

Secure the shank firmly in the tool chuck before operation and confirm the tool is set to a speed appropriate for wire brushes. Wear safety glasses whenever operating rotary wire brushes, as wire strands can shed under load. Disconnect or power down any associated system before inserting the brush into live plumbing or HVAC components. Inspect bristles before each use and discard the brush if wires are significantly bent, broken, or missing.
