Elvis Nickel Alloys is a high-performance Duplex Tube Fittings premium supplier based in Houston, USA. Our fittings are designed for harsh high-pressure and high-corrosion applications, providing leak-free, resistant solutions for numerous tubing systems. We are a supplier of a broad range of compression fittings, ferrule fittings, adapters, and connectors, all made to international quality standards. Applied in critical instrumentation and control applications, our Duplex Tube Fittings are appreciated for their superior strength, resistance to corrosion, and dimensional stability. Our dedication to quality, customization, and technical support positions us as a reliable partner for challenging tube fitting applications.
Duplex Tube Fittings are manufactured from alloy S32205 having 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen. This writing guarantees outstanding mechanical behavior like tensile strength of approximately 620 MPa and yield strength over 450 MPa. The fittings have a good hardness and elongation of 25% and provide excellent flexibility and resistance to fatigue. Their duplex microstructure also provides good resistance to pitting, crevice corrosion, and chloride-stress cracking. These make them suitable for the purpose of having secure, high-performance connections in aggressive service conditions with pressure, temperature, and corrosive fluid.

Duplex Tube Fittings are best suited for instrumentation lines, hydraulic tubing, chemical injection lines, and high-pressure fluid control lines. They are corrosion-resistant and hence appropriate for offshore drilling platforms, refineries, and marine platforms. These fittings have wide application in analytical units, drug processing units, and heat exchangers for clean, safe fluid transfer. They create snug sealing and avoid leakage in high-temperature and high-pressure systems. They are used by oil & gas, chemical process, and water treatment industries for accurate control of flow, safety, and durability in corrosive environments.
