Schaefer Brush 93607 Tube Brush 7/16 in Brass Bristles

Product Description

The SCHAEFER BRUSH 93607 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore passages. The brush features brass bristles mounted on a double stem wire construction, which provides consistent radial pressure against the tube wall during cleaning passes. At 7/16 inch in diameter and 6-1/4 inches in overall length, with a 4-inch brush scraper length, this tool fits compact tubing applications where cleaning access is limited. The male connection end allows it to be used handheld or attached to a compatible extension. Brass bristles resist corrosion and are suitable for use on soft-metal tubing without aggressive abrasion.

This tube brush is suited for residential and light commercial maintenance work involving copper tubing, heat exchanger tubes, condenser tubes, and similar small-diameter passages. HVAC technicians, plumbers, and refrigeration service pros use brushes in this size range for clearing scale, flux residue, oxidation, and debris from tube interiors before inspection or reassembly. The compact size makes it practical for tight service bays and confined equipment interiors.

Compatibility

Designed as a general-purpose tube brush for cleaning small-diameter tube and pipe interiors; verify inside diameter of the target tube against the 7/16 inch brush diameter before use.

Installation Notes

Tube brushes of this type are used by HVAC technicians, plumbers, and refrigeration mechanics during service and maintenance procedures. Relieve system pressure and ensure the tube or component being cleaned is isolated and depressurized before inserting the brush. Insert with steady, consistent strokes and avoid forcing the brush into bends that exceed its flex tolerance. Flush debris from the tube after brushing to prevent contamination of the reassembled system.
