Flaring hard line for AN - The 1947 - Present Chevrolet & GMC Truck Message Board Network

davepl · 05-05-2018, 10:01 AM

I want to go from hard 3/8 stainless line to AN, so I was going to use my hydraulic flaring tool with a 37-degree die.

I have the -6 tube nuts and rings...

Is it as simple as put the nut and ring on, single-flare it 37 and you're done? Seems too easy!

Any tips or tricks are welcome. I've done a lot of double-flare stuff but have never done a hardline AN flare ever!

That's the way I've done it. Same as you, I've done lots of double flares but only a couple of AN.

I have used an adapter that had a compression fitting on one side and -8 on the other.

That's it! Just make sure your ends are nice and square and de-blurred properly. Use some lube on your dies too.

is AN 37 degrees? so SAE is 45 degrees or something like that?

AN is 37 1/2*. The link should help explain.

This... an and jic are basically the same just a different quality of fittings between the 2. Sae isn’t the same.
