    Anyone use Rehau radiant pex tubing? What type of fittings and is there a special tool?

    Rehau has their own proprietary fittings but I also have a bulletin from them approving the use of crimp rings with their tubing. I'm not certain as to whether the information in that bulletin has changed.
    It's all in the details.

    Hope this helps.

    Not as old as I thought.
