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 brush can be used as a replacement brush with any Oil-Rite Roto Shank Brush or Roto Valve Brush. The bristles are stainless steel (nylon is also available, part no. A2440-2).
