Is everyone using "this" washer?

For spacing on the brew pot around the O Ring element connection.
I thought the Kal way made a washer because it wasn't available.Yet everything I buy for my build shows this "Related".I was going to make one and was dreading it as I don't have a drill press

Looks like it'll work assuming you have a 1.5" inner hole.

That's the one I'm using. It's actually not for a 1-1/2in inner hole though. It's over sized so that it fits around the O ring.
