LP350 hose replacement

I've got these hoses from Bhogart. They are reminiscent of the pressure washer hoses I used to use and watch BURST regularly. Any advice on how often they should be replaced? I have run VERY cold gas through them more than a few times and have nightmares about one bursting.

I've seen them crack. replace with PTFE lined, stainless braided hoses with JIC connections. you will have to change your hose adapters but it is worth the trouble with the peace of mind that you gain.
