Weiler 98543 Steel Tube Brush 1 in Single Spiral

Product Description

The WEILER 98543 is a single-spiral steel tube brush designed for cleaning the interior surfaces of small-diameter tubes, pipes, and bores. The brush head measures 1 inch in length with a 3/8 inch brush diameter, making it well-suited for tight passages where larger brushes cannot reach. A 0.004 inch steel wire fill provides firm scrubbing action against deposits, scale, and debris. The 1/8 inch stainless steel shank connects to the brush and allows chucking into a drill or hand tool. Overall length is 3.5 inches. HVAC technicians, plumbers, and electricians commonly use brushes of this type for tube prep, port cleaning, and general maintenance tasks.

This brush is used in applications requiring interior cleaning of small tubing, orifice ports, or connector bores. Its compact size suits residential and light commercial service work where precision cleaning of narrow openings is required. The single-spiral construction delivers consistent contact along the full brush length. It is well-matched to bench or handheld drill use during routine maintenance and repair procedures.

Installation Notes

Install the 1/8 inch shank into a hand drill or pin vise before use. Ensure any system being serviced is depressurized and de-energized before inserting the brush into ports or tubing. Do not force the brush into openings smaller than the rated brush diameter, as this can damage the fill wires. Dispose of worn brushes when wire bristle loss is visible to avoid contaminating the work surface.
