Schaefer Brush 93482 Spiral Tube Brush 0.5in 8-32 Male

Product Description

The SCHAEFER BRUSH 93482 is a single stem spiral tube brush designed for cleaning and deburring the interior of small-diameter tubes, ports, and passages. The brush head is constructed from silicone carbide impregnated nylon, a material that combines mild abrasive action with chemical resistance and flexibility. The overall length is 4.75 inches, with a brush length of 3 inches and a working diameter of 0.5 inches. An 8-32 male threaded connection at the stem allows the brush to mount directly to compatible extension rods or power drive handles. This type of brush is commonly used by HVAC technicians, plumbers, and maintenance professionals who need a consistent, repeatable tool for bore cleaning.

This brush suits applications where debris, scale, light corrosion, or residue must be removed from tube interiors with diameters near 0.5 inches. Typical use cases include cleaning heat exchanger tubes, copper fitting bores, small pipe threads, and condenser or evaporator port passages. The spiral stem design maintains contact along the full brush length during rotation. The 8-32 male thread is a standard size compatible with many commercially available extension handles and drill chucks used in light maintenance work across HVAC, plumbing, and industrial service environments.

Installation Notes

Thread the 8-32 male stem securely into the receiving handle or extension rod before use. When driving with a power drill, use low speed settings to avoid brush distortion or premature wear. Ensure the tube or bore being cleaned is free of pressurized fluid before inserting the brush. Inspect the brush fill for wear or fiber loss after extended use and replace when cleaning performance drops.
