Can gas barb be used for 3/8'' ID hose?

Yes , but you need to clamp it tight.

What size is the bore ?

Thank you for your question. The swivel nut is standard 7/16-20 UNF thread.

The barbs seems smaller than advertised….the 5/16 is definitely smaller than regulator 5/16. Why is that

Thank you for your question. Some 5/16'' barbs of keg regulators are 3/8'' barbs actually.

Good enough?

Cheaper materialism that the existing (more expensive) ones I have. But they don’t leak so I’m sure they will be fine as long as they aren’t abused.

Perfect fit on my old Pepsi Ball-lock kegs

Perfect fit on my old Pepsi Ball-lock kegs, easy cleaning and all gaskets were actually installed (You may not or don't know how much of a problem this can be). Great product.

Cheap, flimsy, and leaks

You get what you pay for. Cheap and not durable. Poppet is made of a weak plastic and and easily bends. As others have mentioned, they do leak.
