Howdy Ray and Mike,
Sorry to be the bearer of bad news, but the nitride 
tube has a hairline crack in it.  It failed leak check.
The crack is visible from the load end, at about 10
o'clock starting from the end (where the seal seats)
continues into the gas inlet flange.  
I left the tube at atmosphere for fear of implosion.
