Thermoplastic flexibility question

Currently looking at getting myself some thermoplastic tubing from NB. looking for anyone with experience with it. my main question is how flexible is it? is it more or less flexible than PEX tubing?

I didn’t know wherelse to find this info. Thanks!

It’s fairly flexible not like a garden hose but you have to keep from bending it to much or it will kink.

It will retain it’s shape with hot water and not collapse I’ve used it for years you just can’t do a sharp 90 deg bend with it.
