Our nipple wrench is heat-treated to a Rockwell hardness of 48–52, which is sufficient for removing most stuck nipples. If the existing nipples are seized due to rust, corrosion, or overtightening, we strongly recommend applying a quality rust or thread penetrant and allowing it to soak for several days before trying again. As with any tool, using it beyond its intended limits can cause it to break.
