Sioux Chief 703-6 Stainless Steel Fitting Brush 1.5 in

Product Description

The SIOUX CHIEF 703-6 is a stainless steel fitting brush designed for cleaning the interior of copper fittings before soldering. The brush features a wire handle for controlled, one-handed use during prep work. At 1-1/2 inch nominal sizing, it matches standard copper fitting bores and removes oxidation, flux residue, and surface contaminants that prevent proper solder adhesion. Licensed plumbers and pipefitters rely on properly cleaned fitting surfaces to achieve leak-free joints, making this type of brush a standard item in any soldering kit.

This brush is used in residential and light commercial plumbing applications wherever 1-1/2 inch nominal copper pipe and fittings are installed or repaired. Typical use cases include new construction rough-in, remodel work, and service calls involving copper drain, waste, and vent lines or copper supply piping at the 1-1/2 inch size. The wire handle design allows the technician to work in confined spaces common in wall cavities and under-cabinet installations.

Key Features

• Stainless steel bristles resist corrosion and maintain stiffness through repeated use
• Wire handle provides grip and reach for fitting prep in tight spaces
• Sized for 1-1/2 inch nominal copper fittings for consistent bore contact
• Removes oxidation and debris to promote proper solder flow and joint integrity

Compatibility

Designed for use with 1-1/2 inch nominal copper fittings in standard plumbing applications. Sized to fit the interior bore of 1-1/2 inch copper couplings, elbows, tees, and similar fittings.

Installation Notes

This tool is used by licensed plumbers during copper pipe preparation prior to soldering. Always shut off the water supply and depressurize the line before beginning any soldering work. Insert the brush fully into the fitting bore and rotate to abrade the interior surface evenly before applying flux. Work performed on potable water systems must comply with applicable local plumbing codes and IPC requirements for lead-free solder and fittings.
