Swagelok® Flexible Metal Hose (FJ Series)
FJ series flexible metal hoses reduce permeation in high-temperature, vacuum, or general-purpose applications where permeation is undesirable.
Get Help Selecting HosesFJ series hose is a general purpose convoluted 316L core stainless steel braided hose with a single braid outer layer of 304 stainless steel promoting hose pressure containment, and an optional 316L stainless steel braid available for greater corrosion resistance. A convoluted core allows for flexibility and limits kinking.
