Hot Seat Head O-Ring Size
Does anyone know the size of the outer O-ring (the big one sealing off the cooling water) on a HS Pro 785 head?

Maybe send 785 Pro Mick a PM. He may know, or can at least ask Bob for you.

I would imagine its the same for all after market heads for the pro785. I know for ada heads its 047. But the chambers don't move or change so you would think that the o-ring would have to sit in the same spot on any head.

That would work except I don't have the o-rings anymore.
I think the 047 is correct because the head groove is a little more than 4-1/2" diameter...more like 4-5/16" diameter. I'll call HS to confirm.
