Schaefer Brush 93628 Tube Brush 7/8 in Brass Bristles

Product Description

The SCHAEFER BRUSH 93628 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore fittings. It features brass bristles mounted on a double-stem wire construction with a single spiral pattern, providing consistent scrubbing contact along the brush length. The overall length is 6.25 inches with a brush scraping length of 4 inches and a working diameter of 0.875 inches. The male connection end allows the brush to be chucked into a drill or used with a compatible extension. Licensed HVAC technicians, plumbers, and pipe fitters rely on this style of brush for tube prep, scale removal, and bore cleaning during service or installation work.

This tube brush is suited for use in residential and light commercial applications where internal tube or bore cleaning is required. Typical uses include cleaning copper tube ends before soldering or brazing, removing scale and oxidation from heat exchanger tubes, and deburring or prepping small-diameter pipe bores. The 0.875-inch diameter makes it a direct fit for common tube and pipe sizes encountered in HVAC and plumbing work. The brass bristle construction resists corrosion and is safe for use on soft metals including copper, brass, and aluminum without risk of ferrous contamination.

Installation Notes

This brush is installed and used by licensed HVAC technicians, plumbers, and maintenance professionals. Before cleaning any tube or pipe section, isolate and depressurize the system in accordance with applicable codes including IPC and IFGC guidelines. When using the brush with a powered drill, operate at low speed to avoid deforming the bristle pattern or damaging soft metal tube walls. Inspect the brush before each use and replace if bristles are significantly worn or splayed, as a deformed brush will not maintain proper bore contact.
