It's fairly common sense with pipe fittings, if there's a taper, that's the seal, no tape required, if it leaks the taper face is damaged, could be either side, I lost a whole bottle of argon once because I didn't check the bottle taper which had a gouge in it. I always check both and spray with soapy water/leak detector spray before leaving them now.
