clutch-line flare and diameter/size ? DIN/ISO or Double/SAE 45 ?

While installing a new JSPEC tranny, we crushed the hard clutch-line.

I have access to a Snap-On flare tool, and I have super-flexible Cunifer alloy brake-lines, but we are not sure what type of flare is used.

We assume it is a DIN/ISO bubble-flare, but can anyone confirm ?

Also, does anyone know the diameter/size ? We think it is 3/16 or 4.75mm.

Thanks in advance,

:-) neil

PS: the Cunifer brake lines do NOT corrode from the inside-out.

FWIW- it is a single-flare 45-degree, and 4.75mm (3/16) in diameter. Make sure you either re-use the stock fittings (if in good condition), or get the proper 45-degree single-flare fitting for a proper seal.

All is good.

Man, you are just flat hardcore, Neil .

I knew it couldn't be too obscure, I had a local hose shop make up a braided clutch line once for me and they did it with parts on the shelf. If the hose ends are easy, the rest should be as well.

Are you sure ?

I showed it to another mechanic, and they said single flare.
And when I went to the parts store, the documentation for the brake lines said Japanese cars use single-flare . . .

It was so easy, I think I'll just make another one with a double flare, just in case . . .

if you look closely you can see where it doubles over itself, it's for creating a stronger crack resistant flare.

sorry for the dirt it's been sitting in my garage for a year.
