Schaefer Brush 14404 Wire Tube Brush 3x3/8 Inch Stainless Steel

Product Description

The SCHAEFER BRUSH 14404 is a single-spiral wire tube brush designed for cleaning small-diameter tubes, bores, and passages in HVAC, plumbing, and industrial maintenance applications. The brush head measures 3 inches long with a 3/8-inch diameter, and the overall assembly reaches 15 inches in length, giving technicians the reach needed to clean heat exchanger tubes, condensate drain lines, refrigerant ports, and similar confined passages. The fill material is stainless steel wire with a 0.005-inch filament diameter, providing corrosion resistance and consistent scrubbing action without shedding fiber debris into sensitive assemblies.

This tube brush is suited for trade and service professionals who need a durable, hand-operated cleaning tool for routine maintenance tasks. Typical applications include clearing mineral scale and oxidation from small-bore metal tubes, cleaning threaded fittings and ports, and general bore maintenance on mechanical and refrigeration equipment. The 15-inch overall length makes it practical for reaching into tight system cavities without requiring disassembly of surrounding components.

Key Features

• Single-spiral construction with stainless steel fill wire for uniform scrubbing coverage
• 3-inch brush length and 3/8-inch brush diameter for small-bore tube cleaning
• 15-inch overall length provides extended reach into confined spaces
• 0.005-inch wire diameter delivers effective cleaning without aggressive material removal
• Stainless steel shank at 0.145-inch diameter resists corrosion in wet service environments

Compatibility

Designed as a general-purpose hand tool for cleaning tubes and bores with an inside diameter of approximately 3/8 inch, suitable for use in HVAC, plumbing, and refrigeration maintenance tasks.

Installation Notes

This brush is a hand-operated cleaning tool requiring no power tools or special installation procedures. Before using in any system component, shut off power, close isolation valves, and verify the passage is depressurized. Avoid forcing the brush through bends tighter than the brush diameter to prevent wire breakage inside the bore. Worn or splayed wire fill should be inspected before each use to prevent debris contamination in cleaned passages.
