I suck at this. Samohon build.

Stupid noob question here. I’m a terrible handyman. Everyone says two inch column and a two inch 90 degree elbow. Well, I got those. I got the elbow that looks to be kind of flared out on each end, assuming that part was slightly bigger so that it would slide over a two inch pipe. But it doesn’t. It doesn’t fit over the two inch couple, either. Did I get the wrong size? I’m lost. TIA.
