Schaefer Brush 93616 Tube Brush 5/8 in Brass Bristles

Product Description

The SCHAEFER BRUSH 93616 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and bores. The brush features brass bristles wound in a single spiral pattern around a double stem wire construction, which provides consistent radial pressure along the full brush length. At 5/8 inch in diameter with a 4-inch brush length and a 6-1/4-inch overall length, it fits standard tube cleaning applications where a rigid, hand-held tool is needed. The male connection end allows attachment to extension handles or machine drive chucks. HVAC technicians, plumbers, and maintenance professionals use this brush to remove scale, debris, and fouling from copper and other soft-metal tubing.

This tube brush is suited for residential and light commercial applications involving tube and pipe maintenance. Common uses include cleaning heat exchanger tubes, condenser tubes, and small-diameter piping in HVAC and plumbing systems. The brass bristle material is appropriate for use on copper, brass, and other non-ferrous tube materials where steel bristles would cause surface damage. The male connection end is compatible with standard extension rod and drive handle systems used in tube cleaning operations.

Installation Notes

This brush is installed by hand or attached to an extension rod or drill chuck via the male connection end. Ensure the tube or bore being cleaned is depressurized and drained before inserting the brush. Work the brush with steady in-and-out strokes to avoid bending the stem or splaying the bristles. Brass bristles are not rated for use inside pressurized systems and are intended for manual or low-speed rotary cleaning only.
