Tank Ping?’s

just out of curiosity, are you guys running a reg still getting ping? if not what is your reg running set up, are you running the o2 adaptor, etac, or something else?

… also what about the angled adaptors out there like Tony’s, are you guys still gettin the ping wile running them?

I’m trying to figure out if the ping wave starts from the valve stem or if its running down the walls of the tank from… say the brass insert, and if the dead space of the adaptors is doing anything to kill the wave…
