Default Which AN adapters go in to 2015 STI steering rack?

The adapters that came with the Chase Bays kit (for 2002 wrx) are the right thread to fit in to the STI rack, but the fitting itself is wrong so they don't go in far enough to seal. There is a tiny brass tube inside the rack with an o-ring on the outside.

The lines are 6 AN, I know that part, but what is the size/name of the fitting that goes in to the rack?

This is what I'm looking at, if it helps:

Did you ever get this figured out? I'm looking into using the same kit

When I did my rack I was unable to find the correct fitting. I believe it's an inverted flare 45deg fitting with metric threads. I couldn't find anything of the sort to adapt to AN.

I ended up using a straight metric to AN steel fitting with a hydraulic o-ring/crush washer. It seems to be working so far even though it's not "correct".

It's also a very tight fit for the 2 fittings so you need steel fittings with smaller hex's. Aluminum fittings have too large of hexs on them and you won't be able to fit them both.

I'll have to dig around to see if i can find what i ordered. Pretty sure i ended up getting them from a hydraulics supply online.

Link removed to what I purchased before.

I believe I found fittings that would actually be considered "correct".

I'll share if i get them in and they'll work.

I ended up just using the hard lines that came with the rack and adapting the ends of those to the AN lines. I used one each of Russell 640820 and Russel 640830. Less than 10 bucks each.

I also removed the plastic clip that holds the lines together. The clip makes it look slightly tidier, but makes it harder to maneuver the lines during installation.

Using the factory lines also meant less cutting to allow clearance.

Let me know if you have more questions. Hopefully I'll have the answers.

I did it the exact same way. My issue is I'm running a stock location external waste gate up pipe, so the ps lines are about 3mm or so from the wastegate flange. I have some dei titanium protect a sleeve on the lines but its just too close for comfort

I'd love to go straight to the rack and route the lines lower similar to stock. I see mooresport has an an line conversion adapter for the 2015 sti rack, but no idea if this will fit with a stock subframe. Ill contact them and post what they say, maybe they have some insight for the right fittings
