Oil-Rite Corp. (Formerly A2257-4X02), Round Brush With Adjustable Shank 1 1/2" Stainless Steel Bristles, 1/8" Male NPT Inlet A2257-SR4

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 Round Shank Brush features an aluminum holder with a 1/8" male NPT inlet to attach directly to a supply line. The bristles are stainless steel (nylon is also available, part no. A2257-NR4). The shank is adjustable to accommodate up to 1/2" of bristle wear.
