Brake lines leaking

[Johnny Blaze]

I installed new brake lines, and used a line wrench to tighten them ,snug. I am getting drips at just about every connection. Lines are new, hoses are new, calipers are new. On the calipers I used copper washers on both sides of the fitting. At the prop valve I am getting a leak too. I did not use any teflon tape or paste. Installed all with dry threads.
