Oatey oat-31329 Fitting Cleaning Brush 1 Inch

Product Description

The OATEY oat-31329 is a heavy-duty fitting cleaning brush designed to clean the inside of copper fittings before soldering. It features high carbon steel bristles that remove oxidation, flux residue, and debris from fitting sockets to ensure a clean mating surface. The brush is sized for 1-inch nominal tube fittings, making it a standard-shop tool for plumbers and pipefitters working with copper sweat connections in residential and commercial plumbing systems. Proper interior cleaning of the fitting socket is a required step before applying flux and completing a soldered joint.

This brush is used wherever copper sweat fittings are assembled, including supply lines, drain and vent connections, and hydronic heating circuits. It is a practical hand tool kept in any plumber's service bag for routine fitting prep work on new installs and repair jobs. The 1-inch nominal size fits standard copper tube fittings in that size range.
