This Valve Brush features a 45° angle 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 stainless steel (nylon is also available, part no. B1049-NR1BHW).
The shank is adjustable to accommodate up to ½” of bristle wear. A replacement brush is readily available.
