    Good afternoon folks, I'm looking for the brass union that connects the front brakes to the master cylinder junction block in a 1970 CJ5. One of the threads fused with the brake line, and this one is garbage. I'm not sure if this part is similar on earlier jeeps, or if it's a '70-'71 part only. The brake switch is redundant, so if the earlier tee is similar, I'm interested in that as well. Please see the pic for reference. Thanks in advance!

    Try a brass brake line T soldered to your old bracket. Drill and tap the tapered thread for the switch if you are daring. The switch does affect the "feel" so removing it will make the brakes less spongy.

    I went to grainger today to look for a tee with the 1/8npt inverted flare on all three sides, and they were no help. I have an extra of the other brake switch tee that sits rearward of the master cylinder, so feasibly could convert it with a 1/8npt to 1/8npt inverted flare fitting, if such a thing exists.

    I'd prefer not to trust anything that I've soldered to stop my jeep!

    Thats a contradiction in terms.
    NPT is tapered pipe thread. Inverted flare is like your steel brake lines, straight thread with a flare on the tube end for sealing.

    Interesting, thanks for the clarification! I knew 1/8npt was tapered, but thought so were the brake line fittings.

    So it looks like i need 3/8-24, that should make things easier in my search!

    Many tap & die sets include a thread pitch gauge. If you get one, make sure it includes the pipe thread tap also.

    I want to thank everyone for their advice on this issue. I was able to get a tee identical to the one jw60 linked to, for a grand total of $5.65. I lose the redundant brake light switch, but my '57 never had that anyways.

    Appreciate everyone's assistance, I should have a shiny new brake system shortly!

    That's what my 1960 has with the large imput from the master cylinder and three smaller lines out the 66 had something different, and the one in question is different again. I ran into this situation when I converted to the dual reservoir and needed a place for the pressure switch... I eventually went with a cap on one outputnof what you show then in the middle of the run I have a tee on one end of the residual valve.

    No that looks different than what was on there.
