Horsehair acid brushes set in tin handles are available. The handle is compressed under immense pressure to securely clamp the bristles and extend the effectiveness of the brush when applying viscose substances, making this brush a great substitute for other brushes that may shed fibers.
Handle diameters range from 3/16", 1/4", 5/16", and 3/8". Disposable acid brushes are typically used to apply glue, acid, lubrication or coatings when the application calls for one-time brush usage. This brush is effective for soldering and seam sealing, in lead work and general-purpose cleaning applications. Acid brushes are packaged and sold by the gross (144-units/package).
