Running all my new lines using the nickel/copper alloy 3/16" line. I have run into a snag going from the one line from the master cylinder to the "T" that splits between the two calipers. The "T" has a female inverted flare fitting (IFF) and the 15" rubber line from the output of the proportioning valve also has a female IFF. Can I just use a brass NPT male to male to couple the rubber line and the "T" together? I dont mind building a little short 6" piece of my 3/16" lines with fittings if need be. Just curious as the npt will just count on the threads to seal instead of the flares. Unless the NPT would happen to bottom out on both ends. Thanks in advance!
