Constructed entirely of MP35N nickel-cobalt alloy, this A.F.O. plug is NACE-compliant and provides excellent corrosion resistance for harsh-duty applications found in the oil and gas industry. This plug uses a metal-to-metal seal for high pressure applications. It is both removable and reusable, providing easy access to sealed passageways . Sizes range from 0.19 to 0.75 inches.
