Help / Advice making stainless lines
 

I've made some smaller -4 lines for oil before, and those were cake.

I'm currently assembling some -8 lines to finish up my fuel system. I've gotten a couple done, but it took me like 2 HOURS. Surely someone has some advice on an easier way to shove the hose nut (the thing you screw the end into) onto the hose? I've tried 30w oil, moly lube and nothing seems to help much.

I've watched my dad put these together as a kid before for his airplanes, and they were NEVER THIS HARD.

I talked to him tonight he said the most important thing was to match brands of AN plumbing hardware with manufactorers of the hose... because they all manufactor the stuff slightly different. Also he mentioned he had a set of mandrels for his press to assist in putting the threaded colar/adapter side on, but thats not where my difficulty lies.

My current method is just as every site on the internet suggests. I wrap the braided hose in electrical tape and then use a chop saw. The braid is clean and not frayed at all. I then unwrap the tape and put the sleeve/nut into the vice and with a twisting motion try to push it in with all of my might... no dice.

Some people have told me some hose ends are threaded on the inside to assist in getting the sleeve over it. IF this is true, WHAT BRAND are they... because I want to use that.

Any advice / tricks you guys have are appreciated!

Oh and FYI the hose ends are Aeroquip. The braided line itself ... I'm unsure. It all came from a local circle track shop.

Sorry for a the long post, frustrated.

they are reverse threads,I always get them on by twisting backwards.

I heat them very slightly so they're a little warm. Don't go overboard with your torch though...melts really easy. Just heat em till they're warm to the touch and spray some wd-40 in there and go to town.

I hate fucken AN fittings. My supplier assembles them, or I don't have them. They're a bitch not worth dealing with if you don't have to.
