leaking brake line fitting

I had the same problem with Fine Lines Stainless Steel lines and I contacted them.

They had a procedure to help seal the flairs using Permatex Thread Sealant With Teflon on the threads and between the line and fitting being careful not to get any sealant on the flare, and it fixed the problem for good.

The problem with stainless steel is it doesn't confirm to the tapered brass fitting like mild steel does, so the sealant helps with the weeping brake fluid.

Trust me, it worked on all of my lines brake lines that were weeping.

If you don't believe me give them a call.
