Weiler 21093 Steel Hand Tube Brush Single Spiral 7 in Oal

Product Description

The WEILER 21093 is a single-spiral steel hand tube brush designed for cleaning the interior of small-diameter tubes, ports, and passages. The brush head measures 1.5 inches in length with a 0.25-inch brush diameter, giving it the reach needed to scrub residue from tight bores without damaging the surrounding material. Wire diameter is 0.005 inches, providing firm but controlled scrubbing action. The 3/32-inch galvanized steel shank extends to a total overall length of 7 inches, and the loop handle style allows for firm hand grip during use. HVAC technicians, plumbers, and pipe fitters commonly use brushes like this for port cleaning, fitting preparation, and general tube maintenance tasks.

This hand tube brush is suited for light to moderate cleaning applications on small-bore tubing, valve ports, fittings, and similar components found in residential and commercial HVAC, plumbing, and refrigeration systems. Its compact brush head size makes it well matched for clearing debris from 1/4-inch diameter openings and similarly sized passages. Sold individually, it is appropriate for both bench work and field service use.

Compatibility

Designed as an OEM-style hand tube brush suitable for general cleaning of 1/4-inch diameter tube bores and ports in HVAC, plumbing, and refrigeration service applications.

Installation Notes

No power tools are required for use with this hand tube brush. Ensure the tube, fitting, or port being cleaned is depressurized and isolated before inserting the brush. Avoid forcing the brush into bores smaller than its rated diameter, as this can deform the wire fill and reduce cleaning effectiveness. Dispose of used brushes that show bent or broken wire filaments to prevent debris contamination inside cleaned components.
