No, because there is no such thing. Are you sure it isn't a typo for NEMA type 6?

Positive. I thought the same thing at first as well. I've gotten some mixed results in my searches, but all at least agree that NEMA 8 is for hazardous locations. Not sure if NEMA 8 would use a NEMA 7 panel and simply has different requirements for the components that go into it.
I had a NEMA document, I stopped reading it at NEMA type 13. But I should have noticed that 7 and 9 were not there either, and I know those numbers were good. Sure enough, all the HazLoc types were at the end of the document. My appologies.

If you use google just search for hazardous location atex rated enclosures, purgable enclosure brings up lots of manufacturers.

Just got off the phone with Adalet, after contacting NEMA for manufacturer recommendations. was basically told "If you find somebody that makes a NEMA 8 box please let us know". In a nutshell I was told that NEMA 8 exists as a rating for oil immersed contacts that would go in to an XP enclosure, and was not intended as a rating for the box itself. Their recommendation for this situation would be a NEMA 7 box with a o-ring grove cut into the enclosure to also give it a NEMA 4 rating. I have a call into NEMA for confirmation.
