are these legal for the game this year?

I think you're down to arguing whether the "port diameter" is less than 1/8" NPT. The nominal diameter of 1/8" NPT is 0.405" and those are 1/4" push fittings, so their diameter is obviously less. So I'm pretty sure they should be legal.

I'd go with the standard "Ask the GDC", but you're nearly guaranteed to get a "We can't rule on the legality of specific items" response. Maybe if you asked for clarification that the rule is specifying that the port diameter is less than the nominal diameter of 1/8" NPT?
