Fittings are normally conventional brake line fittings, 3/8-24 for a 3/16 flare. Some are male others are female(inverted).
The Kodiak calipers take a male fitting in an inverted flare adapter as does a Hydrastar actuator. Anything in between - could be either, depending on who does the makeup - but are 3/16 flare normally, inverted or regular.
Confusing? That's what I meant, above, about doing your homework
