Tubing Flare

[Gezer]

I need to make a flare on each end of a 3/16 copper tubing for the vac line from the carb to the distributor. (53, 8ba)

How do you do that> Is it a bubble flare?

[fordor41]

doubt in '53 there was anything but inverted flares in US. use a brake line flaring tool

They used specific nuts that tapered down and crimped into the pipe (slightly) I think they are available or you might be able to salvage some from an older pipe or odd ends in old manifolds.

Put this part number into a search on rockauto.

First, it is a steel tube,(use brake line) not a copper tube.
If the pinch nut is not available it can be replicated by using a flare nut with a ferrule.

Those nuts are hard to find locally, but 3rd gen has them I believe

I have seen those "pinch" nuts referred to as "Ford nuts" maybe in the Dorman line. Drake used to have them (like a lot of things).

Top picture is what I am looking for. I was uncertain about the correct nomenclature of the nut. Yeah, the tube probably is copper plated steel. I was concentrating on the nut. Also, there were two different size "pinch nuts" (Ouch, that smarts.) on these manifold vacuum tubes, roughly 1/4" & 3/8". Anyone know which size is correct. I know, I am obsessing over "correctness" on this project, but that's just the way I am put together I guess.

(That's the size of the head of the nut, not the size of the tubing,) Anyone know which size is correct.

Ford used them well up into the 60s until the metal lines went the way of the dodo bird.

Eaton/Aeroquip's number is still 6100X3. This was the Weatherhead number if I remember correctly.

We have a big bag of those brass pinch nuts in stock……
