LFMC NPT

[wireday]

I noticed searching for LFMC connectors and they say they are NPT threads, have they always been that way,I tried one in a RGC box hub and it bottomed out with just hand tight. when I try a RGC nipple into the RGC box hub it tightens up half way our so, like usual.

I just measured two different ones with my dial calipers and it was hard to tell due to the low quality of the threads, but they looked mostly straight.

You need to get ones for hazardous locations and they will have real NPT threads
