Schaefer Brush 42939 Tampico Fiber Tube Brush 1.5 in

Product Description

The SCHAEFER BRUSH 42939 is a single stem, single spiral tube brush with a Tampico fiber fill, designed for cleaning the interior of tubes, pipes, and cylindrical passages. The brush measures 1.5 inches in diameter with an 8-inch overall length and a 4.5-inch brush length. The 0.25-inch NPSM male connection at the stem end allows the brush to thread onto extension rods or standard cleaning handles. Tampico fiber is a natural agave-based bristle material well suited for light abrasion and moisture-tolerant scrubbing applications. Licensed tradespeople and maintenance technicians use this style of brush during system cleaning, descaling prep, and tube-side maintenance work.

This tube brush is appropriate for residential and light commercial maintenance tasks involving pipe and tube interiors in plumbing, HVAC, and general industrial cleaning scenarios. The 1.5-inch diameter targets standard small-bore tubing and pipe openings. The NPSM male threaded stem makes it compatible with threaded extension handles and brush-drive attachments commonly found in field service kits. It is a single-unit item with a minimum order quantity of one.
