Schaefer Brush 93488 Spiral Tube Brush 1-1/4 in 6-1/4 in Oal

Product Description

The SCHAEFER BRUSH 93488 is a single stem spiral tube brush designed for cleaning the interior of tubes, pipes, and bores in industrial and mechanical maintenance applications. The brush head is made from silicone carbide impregnated nylon, which provides abrasive scrubbing action while remaining flexible enough to conform to tube walls. At 1-1/4 inches in diameter with a 4-inch brush length and a 6-1/4-inch overall length, this brush fits a specific range of tube bore sizes. The male connection end allows it to be chucked into a drill or extension handle for powered or manual operation.

This tube brush is suited for deburring, cleaning, and surface finishing inside tubing and pipe fittings. Typical applications include HVAC coil and condenser tube maintenance, heat exchanger cleaning, and general pipe bore prep in plumbing and mechanical systems. The silicone carbide impregnated nylon bristles handle light to moderate abrasive cleaning tasks without requiring aggressive tooling. It is commonly used by HVAC technicians, pipefitters, and maintenance mechanics working on tube-and-shell equipment or similar assemblies.

Installation Notes

This brush is installed by a technician or mechanic as a cleaning tool, not a permanent system component. When used in powered applications, secure the male connection end firmly in a drill chuck before operation. Ensure the tube or pipe being cleaned is depressurized, cooled, and isolated from flow before inserting the brush. Wear appropriate eye protection when operating any abrasive brush at speed.
