Schaefer Brush 93619 Tube Brush 11/16 in Brass Bristles

Product Description

The SCHAEFER BRUSH 93619 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-diameter bores. The brush features a brass bristle construction over a brass core, delivering adequate scrubbing action without damaging softer metal tube walls. At 11/16 inches in diameter and 6-1/4 inches overall length, with a brush scrubbing length of 4 inches, this tool fits standard cleaning tasks on HVAC heat exchangers, refrigeration tubing, plumbing fittings, and condensate drain lines. The male connection end accommodates standard brush extension rods. It is a hand-tool item suited for plumbers, HVAC technicians, and refrigeration service professionals.

This tube brush is used wherever tube interior surfaces require mechanical cleaning prior to brazing, soldering, or inspection. Common applications include clearing debris and oxidation from copper or brass tube ends, cleaning heat exchanger tubes, and prepping fittings in residential and light commercial HVAC and plumbing systems. The 11/16-inch diameter fits small-bore tubing common across refrigeration and hydronic piping work. The male connection allows use with compatible extension handles for added reach on deeper tube runs.

Designed as a direct-use tube brush for 11/16-inch diameter tube and pipe bores in residential and light commercial HVAC, refrigeration, and plumbing applications.

Installation Notes

No power tools are required — this brush is used by hand or with a compatible extension rod. Before brushing, ensure the tube or system is depressurized and any refrigerant or fluid has been properly recovered or isolated per applicable codes. Avoid forcing the brush into undersized bores, as overloading the spiral can deform the stem. Replace the brush when bristles show visible wear or splaying to maintain effective cleaning.
