Schaefer Brush 93519 Tube Brush 11/16 in Stainless Steel

Product Description

The SCHAEFER BRUSH 93519 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and bores. The brush features stainless steel bristles mounted on a stainless steel stem construction, making it suitable for applications where corrosion resistance is required. It measures 11/16 inches in diameter with a brush length of 4 inches and an overall length of 6.25 inches. The male connection end allows the brush to be chucked into a drill or extended with compatible rod sets. Plumbers, HVAC technicians, and maintenance professionals use this brush for condenser tube cleaning, heat exchanger service, and general pipe bore maintenance.

This tube brush is suited for residential and commercial service work where small-diameter tube or pipe interiors need to be cleaned of scale, debris, or fouling. The stainless steel bristle material holds up to mildly corrosive environments and repeated use in wet or chemical-exposed service conditions. It is a standard hand-tool or drill-driven brush used by HVAC technicians cleaning condenser or evaporator tubes, plumbers clearing pipe bores, and industrial maintenance personnel servicing heat exchangers or similar equipment.

Installation Notes

Shut down and isolate any system before inserting the brush into active tubes or pipe runs. When using with a drill, operate at low speed to avoid bristle flaring or stem damage. Inspect bristles before each use and replace the brush if wires are bent, broken, or heavily worn. Use appropriate personal protective equipment when cleaning tubes that may contain scale, chemical residue, or biological fouling.
