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.

Thanks, do you have a copy of that bulletin?

Tinman

Hope this helps.

Not as old as I thought.
