Swagelok^® Metal Tubing (FZ and FN Series)

FZ and FN series metal tubing reduce permeation in high-temperature vacuum and low-pressure applications.

FZ Series Metal Tubing

The FZ series is a zero-braid version of the FJ series hose and is an option for applications that do not experience pressures that require a braid on the core tube. This non-annealed all-metal tubing can be used in dynamic applications.

FN Series Metal Tubing

The FN series is an annealed, zero-braid version of the FJ series hose and is an option for convoluted metal tube (CT) applications. The form-fit-and-stay capability of its assemblies can compensate for misalignment and system reroutes between static connections in vacuum or low-pressure static applications. It is not intended for dynamic applications.

The FZ and FN series 316L stainless steel tubing are designed to meet the needs of high-temperature vacuum or low-pressure applications where permeation is undesirable. Custom assemblies are available with other options including tubing tags, additional cleaning, and additional helium leak testing.
