I can stipulate that there are many of these fittings, and that assuming they are all the same is not warranted
and additionally that I have MUCH more actual data than others, most of which is ‘unpublished’;
so what is quite clear to me is often not so to people without a background in the subject
jeez,
the 462 mod is not relevant -> compare the effect of changing the connectors
did you not understand the previous post ? (or is this just about being 'right' now ?)
below are the 2 I have compared
the push-in 90 is that of Swiftech, marked "UK MADE 3/8"; min. ID ~5.2mm
the straight is from Innovatek (and also a Korean mfgr), no markings; min. ID ~7.1mm
while a ¼”NPT x ½” barb has an ID of ~8.7mm
now another of the graphs you love to hate,
this time comparing the connectors on the Innovatek
what are the conclusions that can be derived from all this ?
if you are content with the adequacy of the present installation -> do nothing, of course
if you wish to improve its performance, junk those 90s forthwith
and so we return, again, to my initial post
bye
