Question Is this flexible brake line-to-caliper connection correct??

Ok, I've been staring at this long enough.
This is a new flexible brake line, from the hard line to the caliper in the wheel well.
I was inspecting the connecting surface back inside the caliper with a little mirror, and I actually am not sure if this is the flex line with the correct mating surface.
Will this line seal correctly with the caliper mating surface?
I scoured WSM and PET to no avail.
Thanks.

When I replaced my flexible lines I didn't look closely at the caliper end of the hose, but I did get familiar with port in caliper as was puffing compressed air through to push pistons out for new seals. Almost certain the ports were in funnels beyond the threaded section, so not a match for your photo. But isn't the critical sale at the nut anyway where it's torqued against caliper body?

PET shows matching pointy end for rear flex hoses at least in my 1987-91 illustration 604-05.

Definitive question is what lines did you order, and from where? What's part number (manufacturer or Porsche) on packaging?

Oh and even more definitive, what MY is your car? Mine is 91 so comments apply to 4-pot Brembos.

Google imaging the part number 928
355 080 02 throws up this for all 78-95 928s. Can't see into 'business end' but looks very similar to your's externally

Thanks for the image above... the car is a 1981, the lines came from one of the big 3 here, or maybe PP.... I've had these since first buying the car, and my old brain can't recall the exact source...

The Goodrich lines I got from Greg for my '83 look similar

I don't think so.

I think the line needs the angle converted, not inverted.

Some manufacturers are now making fittings that do both, but the narrow edge on the rim of the inverted portion of your fitting is very thin (and looks to be 90 degrees) in this area and I don't think this is that style of a fitting.

Yes, intended to be used withbubble flared hard lines. If you have double fkared hard lines that look like a funnel, you have the wrong hard line. The double flare that looks like a funnel is for american cars. European cars esp german have the DIN bubble flare.
The bubble flare should not be made of copper but a special steel.
