Schaefer Brush 14646 Brass Wire Tube Brush 3x0.5 in

Product Description

The SCHAEFER BRUSH 14646 is a long-handle brass wire tube brush designed for cleaning the interior of tubes, pipes, and small-diameter bores. The brush head measures 3 inches in length with a 0.5 inch diameter, and the overall assembly extends 27 inches, giving technicians reach into deep or confined passages without bending or adapters. The brass fill material is non-sparking and resists corrosion, making it suitable for use on softer metals, brass fittings, and copper tubing commonly found in HVAC, plumbing, and refrigeration work. Wire diameter is 0.006 inches and the shank diameter is 0.17 inches.

This tube brush is well suited for field and shop use across HVAC, plumbing, and refrigeration trades. Common applications include cleaning burner orifice ports, tube sheet bores, heat exchanger tubes, and pipe interiors prior to soldering or inspection. The 27-inch overall length allows service of tube bundles and deep fittings that shorter brushes cannot reach. The single spiral construction provides consistent contact around the bore wall with each pass.

Installation Notes

This brush is a hand-operated cleaning tool and requires no special tools or power source. Isolate and depressurize any line, tube, or fitting before inserting the brush. Inspect the wire fill before each use and replace if bristles are bent, missing, or broken to avoid leaving debris inside the bore. Brass fill is not suitable for use in applications requiring a ferrous or abrasive media.
