Will this fit a 16in Dia x 22in high drum and can it be used for
12.5% liquid bleach Hypochlorite solution? If not can you suggest an appropriate gauge?
This gauge will fit a 22" drum with a 2" NPT fitting. The manufacturer lists : "Sulphuric Acid, Bleach, Hydrochloric Acid, Acetone, Chlorine, Caustics, and more" as acceptable chemicals for this gauge which should work for your application. Thanks for using Grainger Ask and Answer.
