You know...I found that, but the 1/8" MPT through me off. I figured it must be different that NPT, but then when you read in the details it states NPT. One question/concern I have is that it states it's for air brake applications with a working pressure of 125 psi. Doesn't a modern braking system run about 1200 psi? I thought I read that somewhere, but I know I'm crazy
