Brush Research Mfg. 84N1000 Helical Nylon Tube Brush

Product Description

The BRUSH RESEARCH MFG. 84N1000 is a single-spiral helical nylon tube brush designed for cleaning, deburring, and surface finishing the interior walls of tubes, pipes, and bores. The brush features a 1-inch brush diameter, a 3-inch brush length, and a 12-inch overall length, making it well-suited for reaching into standard-length tube sections. The 0.017-inch nylon filaments provide consistent, non-abrasive contact with the bore surface, while the 0.22-inch diameter galvanized steel shank offers secure chucking in a drill or drive tool. Plumbers, HVAC technicians, and industrial maintenance professionals install this brush for routine tube and pipe maintenance tasks.

This brush is used in applications requiring interior bore cleaning, light deburring, or surface preparation on tubes and pipes found in plumbing systems, HVAC coil assemblies, hydraulic lines, and general industrial equipment. The single-spiral construction ensures uniform filament contact along the full brush length. Its nylon fill is appropriate for use on softer metals, plastics, and coated surfaces where wire bristles would cause damage. The 12-inch overall length accommodates moderate tube depths without an extension.

Key Features

• Single-spiral helical configuration delivers consistent, even filament contact with tube walls
• Nylon fill material is safe for use on soft metals, plastics, and coated interior surfaces
• 1-inch brush diameter fits standard tube and pipe bore sizes in plumbing and HVAC applications
• 0.017-inch filament diameter provides controlled, uniform scrubbing action
• 0.22-inch galvanized steel shank accepts standard drill chucks and drive adapters
• 12-inch overall length provides reach into tube assemblies without requiring an extension

Compatibility

Designed as an OEM-style replacement tube brush for use in 1-inch nominal bore tubes and pipes across plumbing, HVAC, and general industrial maintenance applications.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or maintenance professionals using a standard hand drill or low-speed rotary drive tool. Chuck the galvanized steel shank securely before operation and confirm the brush diameter is appropriate for the bore being serviced. Always de-energize and depressurize any system before inserting the brush into a tube or pipe section. Do not exceed the recommended rotational speed for nylon-fill brushes, as excessive speed can cause premature filament wear or deformation.
