Schaefer Brush 43736 Spiral Tube Brush 1-1/4 in Nylon

Product Description

The SCHAEFER BRUSH 43736 is a single stem spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore fittings. It measures 1-1/4 inches in diameter with a 7-1/4 inch overall length and a 5-inch brush length. The bristles and brush body are both constructed from nylon, making this brush suitable for applications where abrasion on softer metal or plastic surfaces is a concern. A 1/4-inch NPSM male connection allows the brush to attach to a handle or extension. HVAC technicians, plumbers, and maintenance professionals use this style of brush for tube cleaning, heat exchanger maintenance, and general pipe bore prep work.

This tube brush is suited for light-duty cleaning in residential and commercial service environments. Typical applications include cleaning copper tube ends before fitting, clearing debris from small-bore pipe sections, and scrubbing the interior of condenser or evaporator tubes during scheduled maintenance. The nylon bristle construction resists common cleaning solvents and mild acids, making it a practical choice for wet or chemically assisted cleaning tasks in plumbing and HVAC service.
