Schaefer Brush 93622 Tube Brush 0.75in Dia Brass Bristles

Product Description

The SCHAEFER BRUSH 93622 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore fittings. The brush features a 0.75 inch diameter with brass bristles and a male connection end, making it suitable for use with standard brush extension handles. At 6.25 inches overall length with a 4 inch brush length, it provides targeted scrubbing reach inside tight passages. Brass bristles are effective for removing scale, debris, and light corrosion from copper, brass, and other non-ferrous surfaces without excessive abrasion. Licensed plumbers, HVAC technicians, and industrial maintenance crews keep this style of brush on hand for routine tube and fitting maintenance.

This tube brush is suited for residential and light commercial applications where pipe and tube interiors require periodic cleaning. Typical uses include cleaning copper tube ends before soldering, clearing debris from heat exchanger tubes, and maintaining condenser or evaporator coil connections. The male connection end allows it to be used alone or threaded onto compatible extension handles for added reach in confined spaces or deeper tube runs.

Installation Notes

This brush is installed and used by plumbers, HVAC technicians, and maintenance professionals. Before cleaning any live system, isolate and depressurize the pipe or tube section and allow it to cool if it has been carrying heated fluids. Insert the brush end into the tube bore and work it in and out with a rotating motion to loosen scale and debris. Dispose of dislodged material appropriately and flush the line before returning the system to service.
