Yeah, why would the DOT spend all that time pressure testing and aproving stupid little fittings when you can just run to Home Depot and get them
Seriously.....
If you're in a pinch, and have a blow out, and cannot get the proper fittings right away, then rocking some hardware store fittings are ok for a quick fix...but that's it. They absolutely are not the same as DOT fittings, either in materials, production, or pressure ratings. The shit you buy at a hardware store is produces for low pressure static use, not at all for the vibrations and general abuse that they will see on your truck.
One fitting failure can put lives and property in jeopardy, why risk it for a couple dollars worth of fittings.
