I believe this is the vent to my plumbing but I’ve never seen a cap like this. Any ideas?

    It’s solid but not very strong. I tried to use a small wrench and it was breaking the nubs. The thing is incredibly tight

      Wrench on one nub, or across two like a bar? Could be they have a tool that engages all 4 nubs at once so they don’t snap off, or thing was over tightened.
