Shorter lengths of Pex-al-pex?

I need to move a radiator and due to the tricky routing, I’m planning on using 3/4” pex-al-pex. Problem is that I only need about 12’ of it. I can’t find anywhere that sells lengths shorter than 300’ — anyone know of options?

    You can buy straight 20' lengths of HePex, maybe use that.

    From what I’ve read, it seems pex-al-pex is the most appropriate — honestly not sure why since in the past, I’ve used he-pex for infloor radiant. Radiators seem like a similar application. Only difference seems to be higher operating temperature for radiators, but the specs for he-pex appear to match pex-al-pex. 

    [EDIT] just did some more reading and it seems oxygen barrier pex would be perfectly fine to use in this application. Thanks for the inspiration, Bob.

    The biggest benefit of Pex-AL-Pex is its relatively low thermal expansion properties compared to Hepex. For a 12' run, it should not be a factor. :)
