If it's in sump, I wouldnt glue it. If it's external, I would and did. You are talking about the skimmer output right? I have several spare schedule 40 spears unions so I can re-do the plumbing from the output side of the union if I ever need to. But I would glue it if running externally. I dont glue the vent pipe on the top side of the output T, that's not necessary as the water doesnt get that high.
