Cupro Nickel Hydraulic Fittings are generally composed of 90/10 or 70/30 copper-nickel alloys, which means they contain 90% copper and 10% nickel (or 70/30), along with small amounts of iron and manganese to boost strength and corrosion resistance. These fittings are known for their impressive resistance to seawater corrosion, stress corrosion cracking, and erosion. With tensile strength ranging from 310 to 520 MPa, depending on the grade, Cupro Nickel ensures durability. Paul Tube Fittings’ hydraulic components are precision-engineered for high-pressure systems, providing secure, leak-free connections that maintain their strength and integrity even under continuous vibration, thermal fluctuations, and corrosive environments.
