Oil cooler line connections

[ghickey]

Good evening,

I have a good one and hopefully will not leave everyone scratching their
heads.

I am replacing the oil cooler lines (just the flex lines) on a 455
engine. On the end of the hard tubes is a flare connection with male
threads and on the end of the flex lines is another flare connection
with female threads. So how does one join these connections together?

I just finished taking some copper washers and adapting them to be used
for a flared fitting. See https://youtu.be/u7WULLs2nV8 to see what I made.

Now that I have more light to work with tonight I started trying to put
everything together and then I realized that both ends were flared I
figure that the copper washer as a flare gasket will not work. Am I wrong?

If both ends were male threads, then It would be a fairly simple trip to
O'Reillys to get a connector that would join both flares together. With
the one end being female threads, that seems to be throwing a wrench
into everything.

Any thoughts?

Thanks.

The YouTube method's simpler & better, but if you can't get copper gaskets,
this can work too (did for me anyway):

JP,
Those aren't flare washers and the ones I got were alright for diesel banjo fittings, but were too hard to put in an SAE flare.

I had bought the Harbor Freight assortment and used my flare tool to make a flat washer into a conical one. It then worked fine in an inversed flare fitting.

And if it isn’t soft enough, just anneal it with a torch.
