Mine has a 2 3/8" diameter , not sure what brand as it onlh has an Airgas sticker on it
I got a name of a place off my ln2 guy or should I say theif for a place in the Harrisburg that may be able to fix it ...... have a message into them and my LN2 guy looking for a rental as I am freezing these 7970's this weekend even if I have to use Dice
TBH though after benching the 280 on ln2 dice just blows ...........
so I am hoping he can find something, it is like small potatoes around here, not much call for this stuff in the Amish country
