    Loads of choices....

    There are many Pex mfg... Uponor (wirsbo) is a great choice.

    3/8 Uponor

    seems to be the most flexible pex I have installed. Warm it up in the sun or in front of a heater helps also.

    I have not tried any of the Pert tube, is it any more flexible?.

    If it is just a short section stainless corrugated solar tube is easy to shape. I would not do an entire radiant job with it.

    Rubber or EPDM hose could be isolated with a HX and non ferrous components.
