Request More Information

FX series hose is a convoluted 316L core stainless steel braided hose with a double braid outer layer of 321 stainless steel promoting hose pressure containtment. A convoluted core allows for flexibility and limits kinking. It is commonly used in high-temperature vacuum and high-pressure corrosive environments or where permeation is undesirable.

A size range of 1/4 through 2 inch, working pressures from vacuum to 6000 psig (413 bar), and a variety of end connections welded in accordance with ASME Boiler and Pressure Vessel Code Section IX allow the FX series hose to meet the needs of a variety of systems. Standard and custom assemblies are available with options including hose covers, hose tags, and additional helium leak testing.
