Mill-Rose offers a complete line of condenser tube and heat exchanger brushes. Our condenser tube and heat exchanger brushes are available in four bristle materials: High Carbon Steel, Stainless Steel, Brass Wire and Nylon. Mill-Rose condenser tube brushes, with self connecting extension rods, have been expanded to include 1/4" diameter brushes. A special 30" extension rod kit has been designed for use with these brushes. Bristle sizes are graduated from .006" on small diameter brushes, to .012" on larger sizes to provide consistent cleaning power. All units are of single stem, single spiral construction. But they are also available in double stem, single spiral, as well as double stem, double spiral construction. Specials dimensions are available upon request.
