Max Tube Fittings stands out as a top manufacturer and supplier of Special Grade Hydraulic Fittings in Delhi, India. We pride ourselves on delivering high-quality fittings designed for high-pressure fluid transfer applications. Crafted from special alloys like Hastelloy, Monel, Inconel, Duplex, Super Duplex, Titanium, and other exotic metals, these hydraulic fittings offer exceptional strength, corrosion resistance, and leak-proof performance. They’re built to endure extreme pressure, temperature, and aggressive fluid media, ensuring dependable operation in demanding industries. Renowned for their precision design, durability, and robust construction, our Special Grade Hydraulic Fittings are trusted for critical applications in oil & gas, aerospace, marine, chemical, and defense sectors.
Our Special Grade Hydraulic Fittings are made from high-performance alloys, including Hastelloy, Monel, Inconel, Duplex, Super Duplex, and Titanium. While their composition can vary, they typically contain nickel, chromium, molybdenum, copper, and iron, providing outstanding corrosion resistance, tensile strength (up to 800 MPa), and yield strength (350–550 MPa). These alloys excel in resisting pitting, stress corrosion cracking, and high-temperature scaling. With an elongation range of 30–45%, these fittings demonstrate remarkable toughness, durability, and pressure-handling capacity, making them incredibly reliable in aggressive fluid systems and harsh environmental conditions.
