Schaefer Brush 43804 Spiral Tube Brush 3/8 in Stainless Steel

Product Description

The SCHAEFER BRUSH 43804 is a double stem spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore components. It features stainless steel bristles mounted on a stainless steel double stem construction, delivering durability in both dry and wet cleaning environments. The brush measures 3/8 inch in diameter with a 6-inch overall length and a 4-inch brush length, making it well suited for reaching into tight passages. It connects via a 12-24 female thread, allowing it to be driven by compatible extension handles or drill attachments. HVAC technicians, plumbers, and maintenance professionals regularly use this tool for tube cleaning, port maintenance, and surface preparation tasks.

This brush is appropriate for residential and commercial service work where consistent bore cleaning is required. Typical applications include cleaning condenser tubes, heat exchanger passages, small-diameter pipe fittings, and other tubular components where debris, scale, or fouling must be removed before service or inspection. The stainless steel construction resists corrosion and holds up under repeated use with common cleaning solutions. The 12-24 female threaded connection makes it compatible with standard extension rod systems used in tube and pipe cleaning setups.

Installation Notes

This brush is installed by threading the 12-24 female end onto a compatible male-threaded extension rod or drill adapter. Ensure the threaded connection is fully engaged before use to prevent the brush from detaching during operation. When using with power equipment, start at low speed to confirm the brush seats correctly in the tube bore. Disconnect any power source or drive tool before changing brushes or extension rods.
