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 features a brass shank with a 1/8" female NPT inlet to attach directly to a supply line.  The 1/2”–20 threaded shank can be secured to a mounting bracket using the plated steel nut.  The bristles are nylon (stainless steel is also available, part no. A2256-SW1). 

The shank is adjustable to accommodate up to 1/2" of bristle wear.  A replacement brush is available without mounting hardware.
