These quality replacement washbrushes from Brush Research work with all systems designed for washing industrial parts. They serve as great tools for automotive work such as transmission parts, oil pumps, and wheel bearings, as well as for commercial cleaning of machined parts, machine and cutting oil removal, and hydraulic cylinder cleaning. The washbrushes feature injection-molded polypropylene handles with synthetic filaments for resistance to solvent cleaners and are ergonomically-styled to help reduce any wrist strain during cleaning.
