This brush is at a 45° angle. It features a drip tube and (2) 1/8” female NPT inlets. A pipe plug installed in one of the inlets can be removed to connect brushes in a series. An adjustable precision needle valve controls the flow rate; it has a friction lock to guard against loosening from vibration.
The 1/2”–20 threaded shank can be secured to a mounting bracket using the plated steel nut and washer. The bristles are nylon (stainless steel is also available, part no B1008-SR1BHW).
The brush is adjustable to accommodate up to ½” of wear. A replacement brush is readily available.
