Mill-rose 4860 Horsehair Tube Brush 0.5 in 9 in Oal

Product Description

The MILL-ROSE 4860 is a horsehair tube brush designed for cleaning the interior of small-diameter tubes, pipes, and fittings. With a 0.5 inch brush diameter and a 9 inch overall length, this hand tool gives technicians the reach and bristle contact needed to clear debris, flux residue, scale, and light corrosion from tube bores. Horsehair bristles are effective on softer tube materials where wire bristles would cause surface damage. HVAC technicians, plumbers, and refrigeration mechanics commonly keep tube brushes like this in their service kits for prep work ahead of soldering, brazing, or fitting installation.

This brush is suited for residential and light commercial applications where tube cleaning is part of routine service or new installation work. Typical uses include cleaning copper tube ends before soldering, clearing debris from short tube sections, and prepping fittings for assembly. The 9 inch overall length makes it manageable in tight mechanical spaces. It is a hand-operated tool requiring no power source.

Key Features

• 0.5 inch brush diameter sized for common small-bore tube and fitting interiors

Compatibility

Designed for use with tubes and fittings having an interior bore compatible with a 0.5 inch diameter brush, typical of small-bore copper, brass, and similar soft-metal tube systems used in HVAC, plumbing, and refrigeration applications.

Installation Notes

This is a hand cleaning tool and does not require installation. Before using on any tube or fitting, ensure the system is depressurized, drained, and isolated from service. Insert and withdraw the brush with straight, controlled strokes to avoid bending the shank or leaving bristles in the tube bore. Dispose of dislodged debris before proceeding with soldering, brazing, or fitting assembly per applicable plumbing and mechanical codes.
