LFMC in plenum alternative

[brackers]

Can anyone help me out on this? Since you can no longer use LFMC in a plenum, what can be used in a plenum that is built for wash down construction. I've been searching and can't come up with an answer. Is there a liquid tight that has a metalic sheath?

...what type of construction involves a plenum that is built for wash downs?

Large air handlers for hospitals would be one situation.
