The SCHAEFER BRUSH 93633 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and cylindrical passages. Built with brass bristles on a brass brush body, it delivers effective scrubbing action without the risk of sparking, making it suitable for use in environments where ferrous contamination or spark hazards are a concern. The brush measures 1 inch in diameter and 6.25 inches in overall length, with a brush scrubbing length of 4 inches. The male connection end allows it to be chucked into a drill or attached to a compatible extension. Plumbers, HVAC technicians, and maintenance professionals regularly use this type of brush for bore cleaning and tube maintenance tasks.
This tube brush is well suited for cleaning copper tubing, heat exchanger tubes, condenser tubes, and similar cylindrical passageways found in residential and light commercial HVAC and plumbing systems. The single spiral construction and double stem provide stable bristle support during rotary or hand cleaning operations. It is a practical tool for field service technicians who need to clear scale, debris, or flux residue from tube interiors prior to fitting or inspection.
Designed as an OEM-style replacement or service brush for tube and pipe cleaning applications requiring a 1 inch diameter brush with a male connection end and brass bristle construction.
This brush is installed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Before cleaning any tube or pipe section, confirm that the system is depressurized and, where applicable, drained. The brush may be used by hand or with a variable-speed drill at low RPM to avoid bristle damage or tube scoring. Inspect bristle condition before each use and retire the brush if bristles are splayed or significantly worn.
