hey friends.
can you help me guys;please?
I have seen something like this:
SA 105 321-2
B16 2M 1
it's about a forged elbow. but i don't know what dose 321-2 refer to?anyone knows?
and of course what about the 1 at the end of " B16 2m 1"?
thank you

It looks some simplified code letters marked on the steel fitting. Just guessing,
"321-2" sounds like a Cat. No.
"B16" for the ASTM/ANSI Code
"2M" for 2000 psi rating

You may find some info by checking it out in the local hardware stores, like Home Depot or Lowe's. Good luck.

Is it a 1" elbow by chance?
