Pro-source 06692 Nylon Bristle Tube Brush 4.5x0.625in

Product Description

The PRO-SOURCE 06692 is a single-spiral nylon bristle tube brush designed for cleaning bores, tubes, and cylindrical passages in HVAC, plumbing, and mechanical service applications. The brush head measures 4.5 inches in length with a 0.625-inch diameter, and the assembly extends to an overall length of 42 inches, giving technicians reach into deep or hard-to-access tubing. Nylon fill material makes it suitable for cleaning without scratching softer metal or plastic tube walls. The 0.012-inch filament diameter provides firm but flexible scrubbing action, and the 0.142-inch galvanized steel shank resists corrosion during wet service work.

This tube brush is suited for residential and light commercial maintenance tasks where tube or bore cleaning is required. Typical applications include clearing scale, debris, or buildup from heat exchanger tubes, refrigerant line fittings, condenser drain lines, pipe fittings, and similar cylindrical passages. The 42-inch overall length accommodates extended reach in tight equipment layouts without requiring additional extensions. HVAC technicians, plumbers, and pipefitters commonly keep brushes of this type in their standard service kits for routine cleaning and inspection prep work.

• Galvanized steel shank resists corrosion in wet or chemical-exposed service environments

Compatibility

Designed for use in 0.625-inch diameter bores and tubes across HVAC, plumbing, and general mechanical maintenance applications.

Installation Notes

This brush is a hand-tool cleaning accessory and does not require power-down procedures on its own; however, always de-energize and lock out equipment before inserting brushes into active systems or live assemblies. Wear appropriate eye and hand protection when clearing debris from tubes. Do not force the brush through restrictions that are smaller than the rated brush diameter, as this can damage filaments and leave debris in the passage.
