Oil Cooler Fittings
 

I ordered a Z1 oil cooler kit the other day. I figure that while I'm down there I may as well add a proper oil pressure gauge. I'm trying to find the most elegant solution to adding the sender. Many people have used T-adapters at the factory sensor location, I came across some hose fitting adapters that look interesting:

I've confirmed that the probe of the Defi gauge I'm installing is 1/8" NPT.

What I'm concerned about is the material of the adapter. It's aluminum. From what I've seen, most other fittings are brass. These don't list a temperature/pressure rating, so... Does anyone have any opinions as to whether or not it's OK to use this?

I'm usually too lazy to click links unless something catches my eye, so if you're like me, here's a pic:

You are good to go with it. You are looking at no more than 115 psi on start-up and redline. And 260~280F max temp.

This is what I used.
