Schaefer Brush 93486 Spiral Tube Brush 1 in Dia 6.25 in Oal

Product Description

The SCHAEFER BRUSH 93486 is a single stem spiral tube brush designed for cleaning and deburring the interior of tubes, pipes, and bores. The brush features a silicone carbide impregnated nylon fill, which provides light abrasive action suitable for removing scale, residue, and surface contaminants from tube walls without damaging the substrate. At 1 inch in diameter with a 4-inch brush length and a 6.25-inch overall length, this brush fits compact access situations common in HVAC coil maintenance, plumbing tube prep, and light industrial cleaning tasks. The male connection end allows it to mount to a standard drill or flex shaft.

This brush is suited for residential and commercial applications where consistent bore cleaning is required. HVAC technicians use spiral tube brushes to clean heat exchanger tubes, condenser tubes, and evaporator coil passages. Plumbers and pipefitters use them for tube end cleaning and light deburring before fitting installation. The silicone carbide impregnated nylon construction handles repeated use in wet or dry conditions and resists chemical exposure common in HVAC and plumbing service environments.

Installation Notes

This brush is installed by trade professionals including HVAC technicians and plumbers performing routine maintenance or pre-installation tube prep. Before use, ensure the system is depressurized and any associated electrical or refrigerant circuits are properly shut down per local codes. When driving with a power tool, use low speed to avoid flex shaft binding or brush deformation. Do not force the brush through obstructions that exceed the rated diameter clearance.
