Flat 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 Flat Brush features an aluminum holder with (2) 7/32" dia mounting holes and (2) 1/8" female NPT inlets to attach directly to supply lines.  The bristles are nylon (stainless steel is also available, see part no. A2258-2X02). 

Replacement brushes that slide into the holder are readily available. This unit utilizes 2 replacement brushes.
