Exactly what mine did, they seem to not be tapped deep enough. I know there is a "L1" Gauge that tells you the proper depth for NPTs to be tapped for proper fit. For the price, I'd think these would be tapped correctly.

i think that’s how I cracked one. Didn’t look like it was screwed in far enough…. Kept tightening till it cracked the case.
