Schaefer Brush 43822 Spiral Tube Brush 3/4 in 6 in Oal Ss

Product Description

The SCHAEFER BRUSH 43822 is a double stem spiral tube brush designed for cleaning the interior of tubes, pipes, and bores. The spiral construction distributes bristle contact evenly along the brush length, making it well-suited for scrubbing residue, scale, and debris from cylindrical surfaces. The bristles and brush body are both stainless steel, providing corrosion resistance and durability in wet or chemically active environments. At 3/4 inch in diameter and 6 inches overall length with a 4-inch brush length, this tool fits standard tube cleaning applications across HVAC, plumbing, and industrial maintenance work. The 12-24 female threaded connection allows attachment to compatible extension rods or handles.

This brush is used wherever internal tube or pipe surfaces need mechanical cleaning — condenser tubes, heat exchanger tubes, boiler tubes, and similar cylindrical passages. It is a common tool for HVAC technicians performing heat exchanger maintenance, plumbers cleaning pipe interiors, and industrial maintenance personnel servicing process equipment. The compact 6-inch overall length suits confined-space access points where longer brushes cannot reach.

Compatibility

Designed for use with 12-24 threaded extension rods and handles. Suitable for cleaning tubes and pipe bores with an internal diameter corresponding to the 3/4-inch brush diameter. No specific equipment compatibility was provided by the manufacturer for this part number.

Installation Notes

This brush is installed by hand or with a compatible drill or rod by HVAC technicians, plumbers, and maintenance personnel. Before cleaning any tube or pipe interior, isolate and de-energize the associated system and relieve any residual pressure per standard lockout/tagout procedures. Ensure the 12-24 threaded connection is fully engaged before applying rotational force to avoid stripping the threads. Inspect bristles for wear or deformation before each use and replace when bristle integrity is compromised.
