It transitions from a 3-1/4-inch male Acme thread—commonly found on large propane storage tanks and delivery hoses—to a 2-inch male NPT pipe thread. You would replace this adapter when threads become damaged or when you need to connect differently sized propane piping. Its all-brass construction provides durability and corrosion resistance in propane and industrial gas service.
