What are double ferrules compression tube fittings?
1. What are Double Ferrules Compression Tube Fittings?
Double ferrule compression tube fittings are mechanical connectors designed to join two sections of tubing securely, creating a leak-tight seal without welding. Comprising a body, front ferrule, back ferrule, and nut, these fittings work by compressing the front ferrule onto the tube to form a seal while the back ferrule grips the tube to prevent slipping. This makes them ideal for high-pressure and high-temperature applications across industries like oil and gas, chemical processing, and aerospace. Stainless steel tube fittings engineered using unique technology and processes, meet performance requirements for various applications. The two-ferrule design, with specialized front and back processing, compensates for tolerances in tube outer diameter, wall thickness, and material hardness, ensuring consistently excellent leak-tight connections.
