Is a 20psi regulator good enough or should I get a 30psig?

So I found this which I know will work for the hose part, but would need an adapter:

And I found this hose, but there is no regulator:

Do I need a regulator?  I would think so but I don't know.

Hi all,

I'm giving forging a go as a hobby and need some assistance. Do any of you know of a hose with a high pressure regulator that can go from a 20lb propane tank and connect to a torch made for a 1lb propane bottle?

Thanks,

JC
