Schaefer Brush 43602 Tube Brush Brass Bristles 0.25 in

Product Description

The SCHAEFER BRUSH 43602 is a double stem, single spiral tube brush designed for cleaning small-diameter tubes, ports, and passages. The brush features brass bristles twisted into a single spiral pattern around a double-stem wire core, providing consistent scrubbing contact along the full brush length. At 0.25 inches in diameter and 4.5 inches overall length, with a 3-inch brush length, it reaches into narrow openings where larger tools cannot. The 8-32 female threaded connection allows attachment to compatible extension rods for added reach. Installed by HVAC technicians, plumbers, and maintenance trades for tube and port cleaning tasks.

This tube brush suits applications requiring thorough cleaning of small-diameter tubes, orifices, heat exchanger passages, and similar confined channels. The brass bristle material is appropriate for use on softer metals and materials where steel bristles would cause scoring or damage. It is commonly used in HVAC coil cleaning, plumbing fitting preparation, and general maintenance cleaning tasks in both residential and light commercial settings.

Compatibility

Designed as an OEM-style replacement and general-use tube brush for small-diameter cleaning applications in HVAC, plumbing, and industrial maintenance where a 0.25-inch brass-bristle tube brush with 8-32 female connection is specified.

Installation Notes

This brush is a hand tool requiring no power or special installation. Ensure the 8-32 female threaded connection is fully engaged before use if attaching to an extension rod. Do not force the brush into passages smaller than the rated diameter, as this can deform the bristles or stem. Dispose of worn brushes when bristle integrity is compromised to maintain cleaning effectiveness.
