SIT tube brushes and pipe brushes clear scale and deposits from boiler and condenser tubes, helping heat-exchange surfaces stay efficient.
All of them run a straight wire filament and go in a drill. The boiler tube brushes are steel, from 22mm to 127mm, and the condenser tube brushes are steel or brass, from 6mm to 25mm. For a long boiler tube, the SIT boiler tube brush extension gives you another 1.5m of reach. There's more on choosing the filament and the fitting in the brush buyer's guide.
