Our Series SFS Stainless Front and Back Ferrule Sets for Tube, made from durable 316SS, are vital components used in hydraulic and instrumentation systems to ensure a secure, leak-free connection between tubing and fittings. Ferrules are small, yet crucial, metal rings that grip the tubing and provide a tight seal when installed with tube nuts. The front ferrule sits against the tubing and forms a seal, while the back ferrule supports the tubing and prevents it from slipping under pressure. Proper installation of these ferrules, in conjunction with the correct tube nuts, ensures a robust mechanical connection that withstands high pressures and prevents leaks. These ferrule sets are perfect for industries requiring reliable, durable, and corrosion-resistant solutions, such as oil & gas, chemical processing, and aerospace.
