Anyone know dimensions and were to source Hog D1 second stage viton orings?

what do you mean? No orifice imprint on them?

Don’t reuse then as an imperfectly aligned orifice imprint (old and new) — which is the most probable case of it happening will lead to a high cracking effort (or just freeflow)

I guess we'll see. It's a rubber seat and with a perfectly centered/round mating face I don't see it being a problem. If's a fairly soft rubber and a decent seat pressure so it should conform to any minor imperfections. If the mating surface was off center I could see having an issue but here I don't. I did vacuum test thus far, will pressure test when I adjust cracking pressure.

getting it centered is almost always impossible, at least with SP regs, since there’s some play between the poppet and the lever feet
Most of the time this is what happens

LP seat rotated, after getting off center orifice indent. Any issue?

But if it works it works

Yeah I don't see it being an issue but time will tell. It certainly may not be perfectly center but the HOGs use a rivet style LP seat. The good is it's pretty much located in the same position by default (Not "rotationally" obviously) but the bad is it cannot be flipped like some of the flat style ones. If the seat was significantly off center I wouldn't even try it but given it is I'm going to run w/ it. I'll test it a bit before jumping in the water but from the design and the softness of the LP seat I cannot see this not sealing.
