Schaefer Brush 93507 Tube Brush 7/16 in Stainless Steel

Product Description

The SCHAEFER BRUSH 93507 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-diameter bores. It features stainless steel bristles mounted on a stainless steel brush body, making it resistant to corrosion and suitable for use in demanding industrial and trade cleaning applications. The brush measures 7/16 inches in diameter with a brush length of 4 inches and an overall length of 6-1/4 inches. The male connection type allows it to be threaded onto compatible extension handles or drive tools. Plumbers, HVAC technicians, and industrial maintenance professionals use this brush for tube prep, flux removal, and bore cleaning tasks.

This tube brush is suited for residential and commercial applications where small-diameter tube or pipe cleaning is required. Typical uses include cleaning copper tube ends before soldering, removing debris from heat exchanger tubes, deburring small bores, and general maintenance cleaning of pipe interiors. The stainless steel construction holds up to repeated use with solvents, cleaning solutions, and abrasive residues without bristle degradation. The single spiral pattern provides consistent scrubbing contact along the full brush length.
