Copper Nickel (CUNI) fittings are made from an alloy of copper and nickel. 70/30 Copper Nickel specifically contains 70% Copper to 30% Nickel (CuNi 70/30). These fittings are highly resistant to corrosion in saltwater environments, which makes Copper Nickel pipe fittings ideal for marine applications. Integral to marine and navy systems, these fittings can include configurations including tees, reducers, and couplings.
