Schaefer Brush 43551 Spiral Tube Brush 2.5 in Stainless Steel

Product Description

The SCHAEFER BRUSH 43551 is a double stem, double/single spiral tube brush built for cleaning the interior of tubes, pipes, and cylindrical passages. The brush measures 2.5 inches in diameter with a 4.5-inch brush length and a 7.25-inch overall length, making it sized for moderate-bore tube cleaning applications. Bristles and the brush body are both constructed from stainless steel, providing corrosion resistance and durability in wet, chemical-exposed, or high-debris environments. The 1/4-inch NPSM male connection allows direct attachment to standard extension handles or power drive equipment. Plumbers, pipefitters, HVAC technicians, and maintenance professionals rely on this brush for thorough mechanical cleaning of tubing interiors.

This tube brush is well suited for residential and light commercial maintenance tasks including boiler tube cleaning, heat exchanger service, condenser tube decontamination, and general pipe bore cleaning. The double stem spiral construction maintains consistent bristle contact around the full interior circumference of the tube, making it effective for removing scale, deposits, and debris from straight-run tubing. The stainless steel construction holds up to repeated use with water, solvents, and mild cleaning agents without significant bristle degradation.

Installation Notes

Installation is performed by trade professionals including plumbers, pipefitters, and HVAC service technicians. Before cleaning any tube or pipe, shut off fluid flow and depressurize the system according to applicable codes and site safety procedures. Attach the brush to a compatible extension handle or power drive via the 1/4-inch NPSM male fitting before inserting into the tube bore. Avoid forcing an oversized brush into undersized tubing, as this can damage bristles and tube walls.
