Can I use sealtite in multi family dwelling in outside well covered area to run feeders to third floor, emt would have to be installed in 26 inch sections due to changes in floor framing at stairway decks, its passing thru storage cabinets and floors. original plan was to pass long sections up from basement, but went awry. it would be about 45 foot run, then emt in side apartment.

LFMC?
Yes as long as you properly secure it and you can say it is not subject to physical damage.
You also need to pull a grounding conductor in the raceway since it is more than 6'
LFNC "carflex" has similar rules once you wade through the references.

Actually tugging in feeders, considering the bends, will be tougher than you expect. I'd lay on the lube and upsize the raceway one bump. Further, I'd really work on my strapping scheme at every direction change. Lastly, I'd make up my pulling head with extra special care.

You might well consider getting MC - coated? - suitable for exterior use.

If it needs a beauty sheath after the fact that's not so bad. Otherwise, a mere paint job could make the MC blend in. While hefting MC may seem tough, going to Aluminum feeder conductors really cuts weight.

my question was more about fire rating and whether pvc jacketed flex was disallowed in bldg over three floors. So I ended up using steel flex and will have to beautify the exposed portions, the customer doesnt like ropey look, maybe walker duct makes covers I could use.I've seen them used to cover multiple coax runs
