Wilwood 260-8419 vs Wilwood 260-10922

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.

Dumb question or what? :razz:

Allow me to rephrase:

For those who went with the 260-8419 (adapters), why did you buy that one instead of the 260-10922? (or vice versa)

Thanks for any help!

Not a dumb Q. It doesnt matter is my answer. Both valves are the same, they flow the same. I think wilwood was just trying to make it simpler for the installer. The valves are the same inside, meaning they flow the same. Prolly small ports. The larger exit thread is just to make the install simpler. Both valves flow the same ammount, and more than you will ever need for the rear brakes. So dont worry about if the larger exit hole means more flow, it doesnt. Both valves will flow much more than you need on the rear brakes. They are the same valve. JR

I wasn't so much worried about flow of the port, I just found it curious that they'd cut 1/8" NPT into a valve, then provide adapters to 3/8-24, and then have different model # with 3/8-24 cut right into it. Seems like most MFG's won't build something unless there's a demand for it, I was curious why the selection between the two was even available... Like you say, just more options/simpler for the installer.

Anyways, thanks for the response JR!
I was probably just over thinking it. :seizure:

The valve with the NPT fitting is to give you the option to run something like a -3 or -4 AN fitting instead of a flare fitting. This way you could just screw an NPT to AN fitting. There are a lot of racers out there who run braided stainless lines instead of hard lines.

I ended up buying the one with the adapters since it was cheaper and easier to find, and gave me the option to run SS braided lines instead if needed. Otherwise adapting a flare fitting to AN is a pain.
