Thought they may be at risk of kinking.
they are corrugated on the outside but smooth on the inside, and coil up like a dream as they don't have a "memory" like the rubber hydraulic hoses.

I have a "charging hose" with ball valves on either end that I keep pressurized so I don't have to purge it or vacuum it before use.

pressurized, not like I leave it with 6 bar, after purging it I close the valves when there is still clean NH3 gas in it.
a coiled up 10-15 meter hose I can hold up with my arm outstretched.

They take being driven over by forklifts, maybe not repeatedly but a couple of times

The hydraulic hoses are also braided, and had one being driven over by a forklift and it was completely blocked, couldn't push 40 bar of N2 through it.
