Stainless Beer Nuts?

[browntown52]

So i expanded my kegerator to three taps and bought more hardware. While setting everything up I was sanitizing some other stuff and threw all the new hardware in the star san.

I bought kits of beer nut, barb, washer and worm gear. Now that I reread the descriptions the barbs and the worm gear were stainless, but not the beer nut.

Also, the female flare connectors, same thing. The barb and hose clamp are stainless but not the flare nut itself. They looked stainless, but tarnished pretty badly in the star san.

So my question is, does anyone make stainless beer nuts and female flare nuts? I know it doesn't touch beer, but I'm always dunking things in star san and every other piece of the operation is stainless so....

Outside of the beverage industry, are these plumbing parts? Something I can buy at McMaster Carr?

If they're tube nuts like I run on fuel lines for the project car, are they 37 or 45 degree? My guesses at mcmaster p/n's if they are:

http://www.mcmaster.com/#50715k324/=rs94oz for female flare, although pipe size seems small, I measure 5/16", but that nut is 1/2" thread.

As a rule, most flares are @ 45 degrees, unless they are "A-N" fittings, which are 37 degrees.

Indeed, most plumbing stuff is 45. I use the ole armynavy 37deg on the car. Just didn't know if there was a wonky crossover in the beverage industry.

So anyone know of stainless beer nuts?
