Made primarily from duplex stainless steel, Duplex BSP and NPT Fittings blend austenitic and ferritic microstructures, giving them outstanding corrosion resistance, mechanical strength, and the ability to withstand stress corrosion cracking. These fittings come with precision-machined BSP (British Standard Pipe) or NPT (National Pipe Thread) threads, ensuring tight, leak-free connections. They boast excellent durability under high pressure, thermal stability, and resistance to wear, erosion, and aggressive fluids. These mechanical properties make Duplex BSP and NPT Fittings perfect for industrial applications that demand reliable, long-term performance, secure threaded connections, and resilience in corrosive or high-pressure settings.
