Norton 69957370182 Bluefire Ss Tube Brush 0.25 in

Product Description

The NORTON 69957370182 is a BlueFire stainless steel tube brush designed for cleaning, deburring, and surface preparation inside tubes, ports, and small-bore fittings. The brush head measures 0.25 inches in diameter with a 1-inch brush length and 1-inch trim length. Stainless steel fill wire at 0.004 inches in diameter provides firm, corrosion-resistant bristle action suitable for use on metal, plastic, and composite tube interiors. The 0.125-inch shank diameter allows the brush to be chucked into a hand drill or used manually. Plumbers, HVAC technicians, and mechanical contractors reach for this tool when cleaning heat exchanger tubes, refrigerant line ports, and small pipe bores prior to fitting or inspection.

This tube brush is well suited for residential and light commercial maintenance applications where access to small-bore tubing is required. Typical use cases include cleaning copper sweat fittings, deburring drilled ports, and surface-prepping tube interiors before brazing or soldering. The stainless steel fill resists chemical degradation and holds up in environments where mild acids, fluxes, or scale inhibitors are present. At 3.5 inches overall length, it fits standard drill chucks and rotary tool collets without modification.

Installation Notes

Licensed HVAC technicians and plumbers typically use tube brushes as part of pre-braze or pre-solder surface preparation. Always depressurize and isolate the line or fitting before inserting the brush. When using with a drill, start at low RPM to avoid flaring the bristles or scoring soft tube walls. Inspect the brush before each use and replace if bristles are bent, missing, or contaminated with incompatible residue.
