At the track on monday I was checking tire pressure and noticed some brake fluid.

It was leaking out the NPT adapter at my wilwood caliper. I cranked it down and it stopped leaking. But not before it tore all the paint off my caliper.

How tight are the NPT fittings supposed to be, I'm worried about stripping out the caliper.

Finger tight plus 1.5 turns, I believe is what they call for npt under 1/2", it's not necessarily a torque spec.

Does one use Teflon here?

I haven't installed mine yet

Victor No. 5 is one of the best. Get it at lowes. I have tested many different types in absurd environments.

Brake fluid will just eat it up from what I've read.

I admit I did not test it on brake fluid. I was just doilng high pressure air, in Ultra low and high temperatures. I didd use it on my brake parts. No failures or leaks yet. 6 months.

Looks like No. 7 would be a better choice...

Loctite is brake fluid safe. I use red for fittings that will not be removed (NPT fitting to caliper), and blue on fittings that may need to be removed.

Maybe I'll try that after I clean and repaint the caliper.

I had to really crank on both the brake line fitting and bleeders on my Wilwoods in order to stop the wet spots. I forget which part of the setup requires thread sealer, I don't think it's at the caliper, though.
