We used to use hydraulic hoses, but they were heavy and would leak over time to form blisters on the outer skin.
That's when we learned we could get them perforated like ranger said
but it would still smell like ammonia around the hoses.
And you could get a nasty surprise when getting in the car in the morning.

Over time, with the consumption rate of hoses, it was cheaper to go for the expensive durable kind instead of the use and throw away.

The hydraulic hoses would have a life span of maybe 6 months with our use and then they'd be leaking so much it wasn't even cost effective to cut out the leaking parts and make shorter hoses.

The type we changed to is steel braided PTFE, same as we use on the plate freezers, they weigh less and and last longer. the set I have now I've had for over 3 years.

Cost is around £40 per meter though, but considering the lifespan I think it's worth it
