I'll take them out and clean the threads, but will be looking to use something more "robust" on the threads this time.
I had the same thing and thought it was the pipe thread but it actually was the tubing/b-nut fitting. It is very hard to tell where the leak comes from as the fluid can run down and pool around the pipe thread making it look like it is the culprit.
Also, the master cylinders can leak a touch from the seal when you first start messing with them. I had a small leak on one cylinder but after a few pumps it cleared itself up.
