Earl's super stock fittings question

[Corwin]

Hey guys, I've tried searching all over for info on this but I'm not coming up with anything. So here's my question-

I'm plumbing my breather box and I'm just about to order Earl's Super stock press-on type fittings but I'm unsure about one thing - can the fitting rotate independently of the hose once they're mated?
Problem I see is if I've got those fittings on both ends of the hose and thread the second end the first one will unthread (or the hose will get twisted)...

Here's the fitting I'm talking about:

Thanks for any help.

Yes it can rotate.

okay, thanks. I know that might have sounded stupid, but I thought maybe you were supposed to press the second end of the hose onto the fitting after it's already attached. But then how would you remove it...
