Schaefer Brush 43383 Spiral Tube Brush 5.5in Dia Npt

Product Description

The SCHAEFER BRUSH 43383 is a double stem spiral tube brush designed for cleaning the interior walls of tubes, pipes, and cylindrical passages. The brush head spans 5.5 inches in diameter and covers a brush length of 4.5 inches, with an overall length of 7.5 inches. The tempered steel wire construction provides the stiffness needed to break up scale, deposits, and debris inside metal tubing. A 1/4 inch male NPT connection allows the brush to thread directly into standard fittings or extension rods for reach into deep passages. HVAC technicians, plumbers, and maintenance professionals use this tool during cleaning and inspection procedures.

This tube brush is suited for industrial and commercial maintenance applications where internal tube surfaces require mechanical cleaning. Typical use cases include heat exchanger tube cleaning, condenser tube service, and general pipe bore maintenance. The spiral double stem design keeps the brush centered in the bore and delivers consistent scrubbing contact around the full circumference of the tube wall. It is sold individually with a minimum order quantity of one.

Installation Notes

Installation and use of this brush is typically performed by HVAC technicians, plumbers, or industrial maintenance personnel. Shut off fluid flow and depressurize the system before inserting any cleaning brush into a live pipe or tube assembly. Thread the 1/4 inch male NPT end into an appropriate handle or extension rod before use to maintain control during scrubbing passes. Inspect the wire fill for damage or wire fatigue before each use and replace the brush if individual wires are broken or splayed.
