Schaefer Brush 43739 Spiral Tube Brush 1.5 in Nylon

Product Description

The SCHAEFER BRUSH 43739 is a single stem spiral tube brush designed for cleaning the interior of tubes, pipes, and cylindrical passages. The brush features a 1.5-inch diameter and a 7.25-inch overall length, with a 5-inch brush scraper length that contacts the working surface. Nylon bristles provide chemical resistance and a firm yet non-abrasive cleaning action suitable for removing light deposits, debris, and residue from tube walls. A 0.25-inch NPSM male connection allows the brush to be attached to an extension rod or power drive. This tool is commonly used by HVAC technicians, plumbers, and maintenance personnel during equipment cleaning and preventive maintenance procedures.

This tube brush is suited for residential and commercial maintenance applications where tube and pipe interiors require periodic cleaning. Typical uses include cleaning heat exchanger tubes, condenser tubes, drain lines, and other cylindrical passages encountered in HVAC, plumbing, and general mechanical systems. The nylon bristle construction makes it appropriate for use in applications where metal bristles could damage softer tube materials or leave metallic contamination.

Installation Notes

This brush is installed by threading the 0.25-inch NPSM male connection into a compatible extension rod, drill adapter, or power drive handle. Always confirm the tube or pipe is depressurized, drained, and isolated before inserting the brush. HVAC technicians and plumbers should follow applicable safety procedures when working with cleaning chemicals in conjunction with this brush. Inspect bristles for wear or deformation before each use and replace if bristle integrity is compromised.
