Stainless steel (SS) tube fittings are robust, corrosion-resistant components designed for securely connecting, controlling, and managing fluid or gas flow in high-pressure, high-temperature, and sanitary systems. Made primarily from SS 304, 316, or 316L, they utilize compression, threaded, or welded mechanisms to provide leak-tight seals. Common types include elbows, tees, unions, and adapters. Key Features & Materials Material Grades: SS 316/316L is preferred for superior corrosion resistance and durability in harsh environments. Types of Connections: Compression Fittings: Use a nut and dual ferrules (front and back) to create a mechanical seal on the tube OD. Threaded Fittings: Feature male or female NPT, BSP, or metric threads for easy assembly. Welded Fittings: Socket weld or butt-weld for permanent, leak-proof, high-pressure joints. Performance: Capable of handling high pressures (up to 6000 psi) and extreme temperatures. Components: Typically include a nut, back ferrule, front ferrule, and fitting body.
