Stub-outs

Hi, new here -- I'm constructing a basement bathroom and am doing the rough-in plumbing prior to inspection. I'm using 1/2" pex tubing instead of copper and I need some advice on how to do the stub-outs for the rough-in. How do I connect the stub-out to the pex tubing?

They make stub-outs for pex.

Thanks -- do they have a specific name?
