Torrington Brush Works offers several varieties of Acid and Pipe Dope Acid Brushes. Our Pipe Dope Acid Brushes are unique brushes that are made like our acid brushes but with a plain sanded wood handle. These brushes are made with heavy gauge aluminum ferrule which is crimped to secure the black bristles in place. Our Black Bristle Acid Brushes contain bright tin plated tubular handles. Ferrule is double crimped and staple set to hold bristle securely in place. The Aluminum Handle Acid Brushes carried by Torrington Brush Works are made.
