Weiler 98356 Helical Power Tube Brush Steel 7/32 Inch

Product Description

The WEILER 98356 is a helical power tube brush designed for cleaning, deburring, and surface conditioning inside tubes, pipes, and bores. Filled with steel wire, it delivers aggressive scrubbing action suited for removing rust, scale, weld spatter, and built-up deposits from interior surfaces. The double spiral configuration distributes bristle contact evenly around the bore wall for consistent results. The 7/32 inch shank diameter mounts directly to compatible rotary power tools. This brush is a standard consumable used by plumbers, pipefitters, HVAC technicians, and maintenance professionals working with ferrous and non-ferrous tubing.

This brush is applied in maintenance, fabrication, and mechanical service settings where tube and pipe ID cleaning is required prior to fitting, inspection, or coating. Common applications include cleaning copper, steel, and stainless tubing in HVAC refrigerant lines, plumbing supply lines, and light industrial piping. It is sized for small-diameter bore work where a standard wheel or cup brush cannot reach.

Compatibility

Designed for use with rotary power tools accepting a 7/32 inch shank, typical of small-diameter power tube brush applications in plumbing, HVAC, and mechanical maintenance work.

Installation Notes

This brush is installed by trade professionals and maintenance technicians using standard rotary power tools or drill presses. Confirm the tool chuck is rated for the 7/32 inch shank before use and ensure all rotating equipment is fully stopped before changing brushes. Eye protection and appropriate PPE should be worn during operation, as wire bristles can shed under load. Inspect the brush for bent or broken fill wires before each use and discard if fill is visibly damaged.
