Schaefer Brush 43825 Spiral Tube Brush 13/16 in Stainless

Product Description

The SCHAEFER BRUSH 43825 is a double stem spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore openings. The spiral stem construction holds stainless steel bristles firmly in place, delivering consistent scrubbing action through the full 4-inch brush length. At 6 inches overall length and 13/16 inch diameter, this brush reaches into confined passages where flat or cylindrical tools cannot. A 12-24 female threaded connection allows it to attach to standard extension rods for added reach. Maintenance technicians, HVAC service pros, and plumbers use this type of brush for tube cleaning in condensers, heat exchangers, and similar equipment.

This brush suits tube and bore cleaning tasks in both residential and light commercial maintenance settings. It is well matched for condenser tube cleaning, heat exchanger maintenance, and general pipe bore debris removal. The stainless steel bristle material holds up against rust and corrosion, making it appropriate for wet or humid service environments. The 12-24 female threaded connection is a common standard, allowing this brush to thread onto widely available extension handles and drill adapters used in the trade.

Installation Notes

Thread the brush securely onto a compatible 12-24 male extension rod or drill adapter before use. Confirm the connection is fully engaged to prevent the brush from detaching inside a tube during service. When using with a drill, operate at low speed to avoid bristle damage and maintain control in confined spaces. Always de-energize and lock out equipment before inserting any cleaning tool into heat exchanger tubes or system components.
