    I saw it a few days ago but can't find it now. Some small, soft, conical (interior?) washers that you insert into the distribution block then install your brake line and fitting and tighten down. Supposedly, seals the connection really well.
    I have to crank the heck outta my fittings to get them to seal! Shouldn't have to put that much torque on 'em. Any help is greatly appreciated!

    If they are new lines tighten and loosen three times before final tightening. Works every time. You will notice each time you tighten, your wrench will move a little farther. I have done it like this for years and it never fails to work.

  3. Copper sealing washers. Should be able to get them from an air conditioning supply house or plumming supply

    They're called ferrules. Available at auto parts store.

    I purchase the conical copper washers at my local NAPA store. They work great on a vintage piece that cannot be replaced. Cure the leak problem.

    Bandaids? They’re used regularly on aircraft and not just to fix a problem leak.

    I haven't done it myself, but I've seen the drilled off head of an alloy ''pop'' rivet used with success..

    Don't forget that in a pinch you can heat up a copper washer and soften it up so it will seal better. Copper will work harden but is easy to anneal.

    More suited towards JIC(AN)& SAE fittings than inverted flare

    I have seen them used many times over the years and they always work perfectly for stubborn leaks and they are definitely not bandaids.

    Professional mechanics use them on vehicles of all kinds including aircraft as has been mentioned.

    These ones are for 45 degree inverted flare fittings.

  16. I never heard of a copper flare gasket before, sounds like a great item for stainless lines. Since I started using cunifer lines, I don't have many leaks.
