The teed off 1-1/2" vent (the cut one on the right side) went to a shower that is no longer there. The bathroom has sufficient venting without this. Can I make a vertical cut at the 90 and plug it using a slip pvc pipe plug (or something else)? I don't know if the vent on the left will be able to move vertically if I cut it, so if I can't plug it without removing the tee, and it won't move vertically, I guess my solution is to replace the connection with four 90s?

Thoughts?

You need a perma-cap. It requires about 3/4" of pipe to glue on. I suggest you glue it on the vertical stub below the 90.
I'm not aware of a code compliant plug, only caps

So I'm having trouble finding something named "perma-cap" but this is what comes up when I search at HD. Is this it?

Also- so it doesn't matter that moisture could collect in the stub?

Thanks!

That's it.
Assuming you're capping a dry vent, moisture shouldn't be an issue.
Your other option is to cut out the tee and couple in a section of pipe. It wouldn't be to difficult. The splice could be as long as you want and you only need about an inch of flex in the vent

Cap it is. Thanks.
