FX Hose Cutaway

This double-braided hose series offers 1/4-inch to 2 inch nominal hose sizes with a temperature range of –325 to 1000°F (–200 to 537°C) and working pressure ranges from vacuum to 6000 psig through vacuum to 1122 psig.

It's all corrosion-resistant metal, from the 316L stainless steel annular convoluted core to the 321 stainless steel double braid layers to the 316 stainless steel end connections, which are welded to the 304 stainless steel collar. It can handle high pressure corrosive environments, high-temperature vacuum environments, and is an excellent choice anywhere permeation is undesirable.

Swagelok FX hose is specifically designed for high pressure applications in chemical, compressed gas, cryogenic, hydrogen and fuel cell, marin, oil and gas, power, and pulp & paper.



High-pressure corrosion resistant all-metal hose with double braid layers of 321 stainless steel that promote hose pressure containment.

Range of end connection options

You have your choice of end connections: Swagelok Tube Adaptors, Swagelok Tube Fittings, female VCO O-ring Face seals, SAE 37-degree (JIC) female swivels, female pipe threads, male pipe threads and tube butt welds.

As with many other Swagelok hoses, you can get optional hose covers, hose tags and helium leak testing.

Getting FX Series hose your way

There's a second kind of flexibility that comes with our hose. That's the flexibility of our technicians who can fabricate hose to your specifications right here at Swagelok Northern California.

Tell us the length you need, the end connections and options you need and how many pieces, and we'll build them for you in our 1,200-square-foot hose shop (all metal hose is manufactured to order in our Swagelok facility in Ohio).

We can test 100 percent of the hoses we make. We can do a hydrostatic test, an immersion test, and pressure decay testing. And we can provide documentation with any hose if requested. If the need ever arises, we can trace each individual hose back to the original assembler. Each assembler, by the way, has to be certified by Swagelok manufacturing engineers to make sure they know how to use the equipment properly and safely.
