I don't think so but with copper its easy to drill and solder, but that was mainly made for mash recirculation with a pump not gravity fed so the ends would need to be capped for you, you could get a 4 way and drill a hole, file a strait to match then solder
I think an easier way would be to use the tee and one leg would elbow up, the other 3 would bend to make the circle, you could probably even do it with a 3 way and have 2 even arks
If I make it, I’d probably use it for mash recirculation as well as sparging. You’re probably right about the ends, they’re probably need to be capped.
so my idea would be use a tee with the center up, use that to connect to a hose or another pipe and the two other ends curl around, you could even put another tee on each of the other ends
