Round Shank 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 Adjustable Shank Round Brush features an aluminum holder with a 1/8" female NPT inlet to attach directly to a supply line.  The bristles are nylon (stainless steel is also available, part no. A2256-SR4).  The 1/2”–20 threaded shank can be secured to a mounting bracket using the plated steel nut. 

The shank is adjustable to accommodate up to 1/2" of bristle wear.
