Nadia Tube Fittings is a well-respected manufacturer and supplier of Cupro Nickel Hydraulic Fittings based in Kuala Lumpur, Malaysia. They specialize in providing reliable and durable solutions for hydraulic and fluid transfer systems. These fittings are crafted to ensure secure, leak-proof, and vibration-resistant connections, making them ideal for demanding hydraulic applications. Thanks to their impressive resistance to seawater corrosion and biofouling, Cupro Nickel Hydraulic Fittings are the go-to choice in marine, offshore, and industrial settings where durability and performance are essential.
These fittings are made from top-notch alloys like Cu-Ni 90/10 (C70600) and Cu-Ni 70/30 (C71500), which are celebrated for their outstanding mechanical properties and corrosion resistance. They boast excellent tensile strength, fatigue resistance, and durability, all while handling high pressures and elevated temperatures with ease. The nickel content significantly boosts their resistance to stress corrosion cracking, erosion, and scaling, even in tough chloride-laden or brackish water conditions. Available in various configurations such as elbows, tees, couplings, and adapters, these fittings are designed to meet international hydraulic standards.
