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:

I used the black Goodridge fittings for all of my oil lines. I bought everything from Mesa hose (I could just go pick them up) or Patrick Motorsports.

No leaks so far, one needed tightening.. (knock wood)

The Koul Tools plastic vice thingies are invaluable. I thought making the hoses was fun.

Wow! No wires poking into your hand?

No wires. (IMG:style_emoticons/default/biggrin.gif)
It’s worth the $35 even if you only use it once. They show it being used in a vice but I found it so easy to use, I could attach a line on one end, thread the line through a hole and then hold the koul tool in my hand to attach the fitting to the other end. I’m going to try the chisel and aluminum block method shown on youtube to cut the lines. Looks cleaner than a cut off wheel.

I've used the chisel and aluminum block method and it works good, you get a clean cut without the wires sticking out all over and no "swarf" on the inside of the hose to clean out. Just keep the chisel really sharp.
