Special Grade Hydraulic Fittings are crafted from high-performance alloys, including stainless steel, duplex and super duplex steel, alloy steel, and nickel-based alloys. These materials provide exceptional tensile strength, high yield strength, and remarkable fatigue resistance. The fittings are designed to resist corrosion, oxidation, and stress cracking, even in harsh environments. Precision heat treatment boosts hardness and dimensional stability, while low permeability ensures leak-proof connections. Their mechanical integrity supports high-pressure ratings, vibration resistance, and long-lasting durability in critical hydraulic systems.
