Pro-source 05147 Brass Twisted Wire Bristle Brush 3x1in

Product Description

The PRO-SOURCE 05147 is a single-spiral brass twisted wire bristle brush designed for cleaning, deburring, and surface preparation in bore holes, tubes, and tight internal passages. The brush head measures 3 inches in length with a 1 inch diameter and is filled with 0.008 inch brass wire filaments that provide firm yet non-sparking scrubbing action. A 0.16 inch galvanized steel shank extends the overall length to 10 inches, allowing reach into deeper cavities. This type of brush is a standard tool for HVAC technicians, plumbers, and pipefitters who need to clean fittings, valve seats, and tubing interiors before brazing, soldering, or inspection.

The 05147 is suited for use in residential and commercial trade applications where internal surface cleaning is required before assembly or repair. Common scenarios include cleaning copper tubing ends ahead of solder joints, deburring drilled ports, and removing scale or debris from valve bodies and heat exchanger tubes. The single-spiral fill pattern provides consistent bristle contact around the full bore circumference. The galvanized steel shank accepts standard drill chuck sizes for powered use or can be turned by hand for manual cleaning passes.

Key Features

• Brass wire fill delivers non-sparking, corrosion-resistant scrubbing action suitable for copper, brass, and soft alloy surfaces
• Single-spiral configuration ensures even bristle distribution and consistent bore contact
• 3 inch brush length and 1 inch brush diameter sized for common tube and fitting bores
• 0.008 inch wire diameter provides firm cleaning without gouging soft base materials
• 10 inch overall length allows reach into deeper passages without direct hand contact
• 0.16 inch galvanized steel shank is compatible with standard drill chucks for powered operation

Compatibility

Designed as a general-purpose internal bore brush for use on copper, brass, and similar soft-alloy tubing, fittings, and valve bodies common to HVAC, plumbing, and pipefitting applications.

Installation Notes

This brush is installed and operated by HVAC technicians, plumbers, and pipefitters as part of surface preparation prior to soldering, brazing, or mechanical assembly. Always de-energize, depressurize, and isolate the section of pipe or component being cleaned before inserting the brush. When used in a power drill, secure the shank fully in the chuck and operate at low speed to avoid wire filament fatigue and breakage. Wear eye protection during use, as wire bristles can shed under load.
