Our Hastelloy BSP and NPT fittings are crafted from nickel-based Hastelloy alloys like C276 or C22, celebrated for their outstanding corrosion resistance in tough environments. These alloys are rich in nickel, molybdenum, chromium, and iron, which together provide impressive tensile strength, toughness, and resistance to pitting and crevice corrosion. These fittings maintain their mechanical integrity even under extreme temperatures and pressures. With precision threading to BSP (British Standard Pipe) or NPT (National Pipe Thread) standards, they guarantee secure, leak-tight connections. Their durability and resistance to corrosion make them perfect for demanding chemical, marine, and high-temperature applications.
