<p>Can't find an M10x1 female to 3an. Doesn't mean it doesn't exist but I haven't found it yet.</p><p>Getting that made in a DOT certified brake line in small quantities is $$$.</p>

Edit: Earls 361-989534
I've got it down to $43 shipped for a wilwood-esque set, m10x1 adapters for $12, 3an npt adapters for $7, 16" 3an line for $24. NPT-NPT brake lines can't exist, I know I can find a NPT to 3AN brake line. I found some, just too long. If I could get those around the same price, there's only one adapter and the lines would be that much cheaper.
I paid $52 something, so about ten bucks cheaper and waiting for multiple shipments.
Why the hell they not just swedge the NPT fitting on there? That's what I thought I was buying. That end of the line does not need to swivel for assembly, not if you do it right.
You can buy the willwood set on ebay for $72 bucks

<p>I assume there is a good reason. Not sure what it is though.</p><p>AN3 is brakeline standard.</p><p>Props to 949. I don't think I can beat their price DIY, especially if I don't want extra dapters, which i don't.</p><p> </p>

<p>I think I know why its 3AN.</p><p>Isn't NPT a compression fitting, and can degrade over time if you take it in and out?</p><p>Whereas 3AN can be used over and over again.</p><p>So you leave the NPT fitting in the caliper and then you can swap calipers as much as you want.</p>

I think I can get a 3an line at the auto parts store, that would be the only other advantage of having that earls adapter fitting.
I can't imagine ever needing to replace lines on the road, and 949 does ship really fast.

NPT is a tapered thread. It's not going to get looser based on taking it on and off unless you overtighten it, but it's something of a PITA because you need something to fill the gaps and seal it (teflon tape or paste), whereas AN uses flared faces that seal to each other dry.
All of the Wilwood lines I've seen (including those from Goodwin, FM, and TSE) are single-piece with NPT threads on one end and Mazda flare nuts on the other end. I'm not sure why it would matter though, because why would you need to take the hydraulic line off the caliper frequently?

NPT is not a compression fitting. A compression fitting is a ferrule with a small slide-on clearance over a tube that gets squished into the tube as you tighten the nut.<br />

<br />Thanks for the correction. Are you sure they are one piece? I couldn't find an M10x1 to npt on wilwoods site.

The Goodwin line on the other side (long story as to why I have a Goodwin line on one side and FM on the other) is the same way. Looking at the photos of the TSE lines that I sold, though, they're clearly using adapters because they're a different color.

You can't have a swivel NPT fitting, or if you do it will have a very complex and weird internal flare much like an AN fitting, so it may as well be a two piece adapter. Assembly without a swivel would be possible, but it would suck.
All these other fittings are a threaded collar pulling a taper seal together.
FM website shows a NPT to 3AN adapter at the caliper. I'm nearly certain that's how they are all done at this point.
