Schaefer Brush 42622 Nylon Tube Brush 6 in Single Spiral

Product Description

The SCHAEFER BRUSH 42622 is a single-spiral nylon tube brush designed for cleaning the interior of tubes, pipes, and cylindrical passages. The brush head measures 6 inches in diameter and 4.5 inches in length, with a 7-inch overall length including the stainless steel shank. The shank diameter is 0.25 inches, making it compatible with standard drill chucks and flexible drive cables. Nylon filaments at 0.045 inches in diameter provide firm but non-abrasive scrubbing action, suitable for removing scale, deposits, and debris without damaging softer tube or pipe wall materials. HVAC technicians, plumbers, and maintenance professionals use this brush for tube cleaning during service and preventive maintenance work.

This brush is suited for both residential and light commercial applications where tube or conduit interior cleaning is required. Common uses include evaporator coil drain tubes, heat exchanger flue passages, condenser tube bundles, and small-diameter pipe bores. The single-spiral construction concentrates bristle contact along the full diameter of the tube bore, ensuring thorough wall coverage in a single pass. The 7-inch overall length allows reach into recessed or hard-to-access passages without requiring extension tools.

Installation Notes

Secure the 0.25-inch shank in a hand drill or flexible drive cable before use, and ensure the drill speed is appropriate for the tube material to avoid filament wear. Power down and isolate any system being serviced before inserting the brush into active passages. Wear appropriate PPE when working with chemical cleaning solutions in combination with this brush.
