Osborn 0007525300 Tube End Fitting Brush Steel Fill

Product Description

The OSBORN 0007525300 is a tube end fitting brush designed to clean and deburr the inside of tube ends and fittings before assembly or inspection. The brush measures 1 inch in brush length with a 41/64 inch brush diameter and a 6-3/8 inch overall length, making it sized for targeted access into tight tube ends. The fill material is steel wire with a 0.008 inch wire diameter, which provides enough stiffness to remove scale, oxidation, and debris from metal tube interiors. This type of hand tool is used by plumbers, HVAC technicians, and pipefitters during prep work on copper, steel, and similar metal tubing systems.

This brush is suited for use in residential and light commercial settings wherever tube end cleaning is part of the installation or maintenance workflow. Common applications include cleaning sweat fitting sockets, deburring tube ends ahead of compression or flare connections, and removing contamination from fittings prior to soldering or brazing. The steel fill construction makes it appropriate for ferrous and non-ferrous metal tube work where a firm abrasive action is required.

Installation Notes

This brush is a manual hand tool and does not require power or special equipment. Always inspect wire fill for splaying or loose filaments before use, and discard if the brush shows significant wear that could leave wire fragments in the fitting. Use appropriate eye protection when brushing metal tube ends, as dislodged scale and wire particles can become projectiles. Ensure the tube or fitting being cleaned is depressurized and free of any residual fluid before beginning prep work.
