Schaefer Brush 43607 Tube Brush 7/16 in Brass Bristles

Product Description

The SCHAEFER BRUSH 43607 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and fittings in trade and industrial maintenance applications. The brush measures 7/16 inches in diameter with an overall length of 6.25 inches and a brush or scraper length of 4 inches. Brass bristles provide effective scrubbing action on soft metals and surfaces where steel bristles would cause damage or contamination. The double stem construction gives the brush added rigidity, supporting consistent contact with tube walls during cleaning passes.

This tube brush is suited for HVAC, plumbing, and general mechanical maintenance tasks where internal bore cleaning is required. Typical applications include cleaning copper tube ends, fittings, valve seats, and heat exchanger passages before soldering, brazing, or reassembly. The 12-24 female threaded connection allows the brush to be mounted on a compatible extension rod for reach into deeper passages. It is commonly used by HVAC technicians, plumbers, and maintenance mechanics in both residential and light commercial service work.

Installation Notes

This brush is installed by hand or with a compatible threaded extension rod using the 12-24 female connection. Before use, ensure the tube or fitting being cleaned is depressurized, de-energized, and free of fluid if installed in a live system. Use controlled rotational strokes to avoid bending the stems or flaring the bristles. Brass bristles are not suitable for use on ferrous surfaces where brass contamination is a concern.
