Roto Brushes are used to apply lubricant to chains and other moving surfaces. The whisking action of the bristles evenly distributes the fluid as it reaches the contact surface. Brushes can also help prevent dirt build up.
This Roto Brush has no holder and can be used as a replacement brush for any Oil-Rite Roto Shank Brush or Roto Valve Brush. The bristles are nylon (stainless steel is also available, part no. A2440-3).
