I bought a set of gas quick disconnects
to put inline between my CO2 regulator and a manifold, and I was wondering if there was a convention on whether the gas should flow from male to female, or female to male. If I ever pool my gear together with someone else, I'd like it if all the equipment works together.
Based on gender-stereotypes alone, I'd suspect that people would normally go from male to female. However, I've seen on some other different disconnects the female connector can be twice the price (due to moving parts), so I could see people optimizing their layouts to minimize the number of female components necessary.
So - is there any convention I should stick to to maximize compatibility?
