Schaefer Brush 42933 Tampico Fiber Tube Brush 1 in

Product Description

The SCHAEFER BRUSH 42933 is a single stem, single spiral tube brush constructed with Tampico fiber bristles and designed for cleaning the interior of tubes, pipes, and similar cylindrical passages. The brush measures 1 inch in diameter and 8 inches in overall length, with a 4.5-inch brush and scraper section. A 1/4-inch NPSM male connection at the stem allows the brush to be threaded onto standard extension handles or drive equipment. Tampico fiber is a natural plant-based filament well suited to general-purpose scrubbing without damaging softer tube surfaces. Licensed tradespeople and maintenance technicians working on HVAC coil tubes, heat exchangers, and plumbing lines commonly use this style of brush.

This tube brush fits standard cleaning and maintenance workflows in HVAC, plumbing, and industrial service. It is sized for 1-inch nominal tube or pipe bores and is appropriate for both residential and light commercial applications. The 1/4-inch NPSM male thread is compatible with common handle extensions, making it practical for cleaning deeper tube runs or coil passages where hand access is limited. The brush is sold individually and is intended for manual or slow-speed rotary cleaning use.

Installation Notes

Installation of this brush requires threading the 1/4-inch NPSM male stem onto a compatible handle extension before use. Always de-pressurize and isolate any piping or tubing system before inserting the brush. Use appropriate personal protective equipment when cleaning lines that have carried chemicals, refrigerants, or wastewater. Operate at slow rotational speeds if used with a drive tool to avoid premature bristle wear or stem damage.
