Ok so I've always had a semi hard on for engine bays with all stainless braided lines. I've always wanted to do this to my car however I do not understand how the little fittings fit over top the hose and all that. So I've decided when I do my heat exchanger plumbing in a month or two that I want to do it all with the stainless lines. Now I know you can buy the line and I know I need 3/4 inch. I found out this is -12AN.

So how do I connect the solid metal tube for example on the dual pass plate to the an fitting
+ = ?

Yea I could use just a hose clamp which is what I'm doing at the moment with regular hose, but I want the stainless lines with fittings I dont understand which fittings i need.


See in this pic theres a hose barb on one end, but the other end is threaded, the dual pass plate, intercooler pump, intercooler, all are not threaded

Have the tubes on the dual pass cut off then drill out the hole if needed and buy a 3/4" npt thread tap and then buy 3/4" npt to 12 an adapter and voilà!

Not doing cutting or welding

and on some parts its kinda cast that way

pretty sure you're gonna have to cut and/or weld the fittings onto the housing.

I think Aeroquip sells a weld on male bung. But the easier way would be to cut off the neck and tap the hole for an adapter.

You can't use the hose you pictured with the fitting you pictured. The fitting you show is an AN fitting, but made for push lock hose (BTW, the only good brand of this is Aeroquip). The hose is standard braided hose, meant to be used with 2 piece re-usable hose ends.

If everything you have is made for a hose barb, you aren't going to get any AN fittings in there. The "look" could be done with one of those braided, slip-on sleeves available at Advance or Autozone.

You could always remove the fitting on the adapter, drill (maybe you wont have to) and tap to a certain size of the hose adapter used.... use your imagination and go with it, there are some good possibilities to make it looks real good!

Well I guess on the dual pass plate, intercooler ends, and the pump I could just run the stainless line over the hose barb and cover it with one of these



Then out to this

Its going to fray. A lot.

The standard braided hose isn't made to go over a barbed fitting. Hose ends are two piece. The silver part in the last pic unthreads and goes over the outside of the hose. The hose goes over the nipple on the black piece, then the silver piece gets threaded back on. The stainless braid is tight, and once its cut (or not clamped by the outside piece of the fitting), it WILL fray. Thats why manufacturers actually make a hose specifically for barbed fittings, it doesn't have the braided covering, since there is no outside piece on the fitting.

This is a socketless barb fitting-

If you really want braided hose, do it right or you're going to have issues. You can't mix and match braided with barbed. Either cut off the factory nipples and thread the holes, or weld on the AN adapters. Those hose end clamp deals you show are junk, and you'll be upset when it all falls apart. If you really just want the look of braided, go with the sleeves from Spectre or something similar. All the look, none of the price.

Here is a good article explaining it all

.

also when you cut the stailess braided lines put electrical tape around it first so that it wont fray on you then the silver piece will cover the tape

thats rice man, and as its been said, the hoses don't work that way.

if you don't want the trouble, use regular hoses.


Assuming its thick enough, the best way is either cut the steel nipples off and drill out and tap the aluminum (very easy.. if this scares you, use regular hoses), or have aluminum fittings welded on.
