Tube Cleaning Brush, Large, Dual Diameter Spin-Grit

Large diameter spin grit brushes are recommended for removing soft and light scale deposits in straight, ferrous and nonferrous internally enhanced tubes. The small diameter end of this brush cleans into the grooves while the large diameter bristles clean the lands of the enhancement. For tubes 1"-1-1/4" (25.4-32mm) I.D.

Note: ESGB Brushes require a #TCB-C Coupling ($8.00) to connect to GTC-720, GTC-721, GTC-721G and GTC-821 Flexible Shafts. (One coupling is supplied with each brush order.)
