Oil line leaks, JEGS AN fittings Options

[worn]

I am running a 911 thermostat and remote oil filter and oil cooler. I figured on going AN fittings since they seem to be abundant and cheap. So I made up some oil lines using SS braided hose and anodized fittings from JEGS. At the time I bought the stuff I could get free shipping and the stuff came pretty much overnight.

Some of the end fittings I used are 45 and 90 degree angles, and they allow the fitting to swivel. I haven't tracked the trouble completely, but it appears that the fittings are leaking at the swivel joints.

Any experience with this sort of problem? Is this inherent to the do it yourself type fittings? They aren't like Aeroquipe in that the fitting doesn't cut into the hose. Instead, the fitting is sort of clamped onto the hose with an outer nut. Are there tricks to assembly that I don't know about?
Like this on my oil cooler:

(IMG:style_emoticons/default/agree.gif) As far as the fittings go they are flared so the compress together. I do not do them everyday so I miss place some info at times, but with mine, once I got them tight they no longer swiveled. Do not use thread sealant on the threads as they do none of the sealing.

They should have a matching flare, so check.

AN fittings are 36 degree

You might have one of the other flares



If that was the case though your AN fitting should not screw onto the fittings. I have never had an issue unless mine where loose.

Thanks all. They are all matched angles. I will check to see if they stop swiveling with tightening. One of the 16AN fittings was clearly leaking at the seal, so I replaced that quite a while ago. Since I don't plan on doing a lot of this I didn't buy the installation tool, although I did buy a TIG to make the tank. I did sand cast an AN16 wrench. My son was pouring an intake manifold, so I made a quick pattern out of plywood.

Have you noticed any differences between brands?
