Hastelloy Gasket for Sulfuric Acid

Q: I have a highly corrosive sulfuric acid application that I need a gasket for a Hastelloy flange. Can you tell me which style gasket would work best?
A: The JP/JG gasket would be the best for your application. Because it can be made from specialty alloys like the Hastelloy alloy grades coupled with PTFE or Graphite sealing materials makes it ideal for highly corrosive applications. The JG/JP gasket design also offers the lowest leak rate available to industry at about 15000x better than a spiral wound gasket.(link to graph)
