Schaefer Brush 43819 Spiral Tube Brush 11/16 in 6 in Oal Ss

Product Description

The SCHAEFER BRUSH 43819 is a double stem spiral tube brush designed for cleaning the interior surfaces of tubes, pipes, and small-diameter bores. The spiral stem construction holds stainless steel bristles securely, delivering consistent scrubbing action throughout the full brush length. At 11/16 inches in diameter and 6 inches overall length with a 4-inch brush length, this tool reaches into confined passages where standard cleaning tools cannot. The 12-24 female threaded connection allows attachment to extension rods or powered handles. Plumbers, HVAC technicians, and industrial maintenance technicians are the primary installers and users of this brush type.

This tube brush is suited for light to moderate deburring, fouling removal, and surface preparation inside metal tubing in both residential and light commercial applications. The stainless steel bristles resist corrosion, making the brush appropriate for use in wet environments or on stainless, copper, and similar metal tube interiors. The 12-24 female threaded connection is a standard thread size compatible with common brush extension rod systems, supporting use in boiler tubes, heat exchanger passages, condenser tubes, and drain lines of comparable bore size.

Key Features

Compatibility

Designed as an OEM-style replacement and standard-service tube brush for use in applications requiring an 11/16-inch diameter spiral brush with a 12-24 female threaded connection.

Installation Notes

This brush is installed by threading the 12-24 female end onto a compatible extension rod or drill chuck adapter before inserting into the tube bore. Verify the bore diameter matches the brush diameter before use to avoid bristle damage or brush lodging. When used with a powered driver, run at low speed and avoid forcing the brush into bends that exceed the brush flexibility. Always wear appropriate eye protection when operating tube brushes in open tube ends.
