Wilwood 260-8419 vs Wilwood 260-10922

[nullshine]

Hey guys/gals,

I have a question on these two Wilwood proportioning valves.
I'm noticing that they're very similar (price, function etc), except that the fittings are
different.

The Wilwood 260-8419 has 1/8" NPT ports, and comes with adapters to 3/8"-20 inverted flare.
The Wilwood 260-10922 has 3/8"-20 inverted flare ports cut right into it.



A couple things come to mind:
If I'm going to run 3/8"-20 fittings into my proportioning valve, why would I go for the 8419 (adapted) valve?
If I'm going to run 1/8" NPT into it, why are the adapters provided to convert to 3/8"-20?

Am I missing something? Or just overthinking it?
Are the brass adapters a better material for the inverted flare, as opposed to the aluminum body of the 10922?

Thanks for any help that can be provided!

PS: I searched this, but couldn't find any information on the pros/cons of the fitting types on these valves.
Also, I checked Wilwood's site, and the installation instructions for both valves go to instructions for the 8419 valves, so no help there.
