Hello all,
I'd love to get your expert opinion on these NPT threads. Are these acceptable for use, or should I send them back? I don't have the expert eye, and they look questionable to me.

- Material is 1" domestic black pipe (21' stick was cut to length)
- Cut by my the fabrication shop at my local plumbing supply store

Thanks in advance!
-Vic

Did they even bother to deburr after cutting? Is this for gas?

I might attempt to use them for compressed air in my own shop, but only if it was the best I could do (it's not). I wouldn't pay someone else for that...

Yup - intended for gas, and no, they did not ream/debur any of the pipe, although that's the least of my worries with threads like this...kind of disappointing really.
Thanks for the input! This guy is going back!
