Copper Nickel Boss fittings are widely used in industries that demand resistance to corrosion and high temperatures. Common applications include marine engineering, desalination plants, offshore oil and gas platforms, shipbuilding, HVAC systems, condensers, and heat exchangers. Due to their anti-biofouling properties, these fittings are also suitable for seawater piping systems and cooling water circuits. Their excellent strength-to-weight ratio and durability make them a preferred choice for critical fluid handling systems..
