AN fittings what the @#$%?
« on: February 02, 2005 - 09:41:49 PM »
Alright... got the bright idea that now I am replacing the the fuel line, I might as well go to SS hose and AN fittings...dumb, should have left well enough alone. Anyway got the hose cut, followed all directions and have had a hell of a time getting the hose into the fitting/cutter piece without the stainless wires getting pushed back and not going in. It says to remove the tape after cutting the hose, but is there a another way? have used oil to lubricate....
Thanks

It's even more fun trying to put them on without scratching them up if you don't have the right tool!  :stomp: :stomp:

Oh Boy,

Long ago, I used to work at Aeroquip and we made the stainless steel braided hose and screw together crimp fittings for aircraft and then we branched into the car market and started making lesser quality hose and fake nuts with the clamp inside for cars. The aerospace hose was way overrated for cars and extremely expensive.

At the time I had a 34 Ford 3 window coupe (sorry guys) and we plumbed every line and hose on the car with aircraft hose an fittings including the 2-1/4  inch radiator hoses. Probly had $1000 worth of aircraft hose on the radiator alone. I actually brazed 2-1/4" threaded hose nipples on the radiator and attached the lines with actual aircraft anodized screw together fittings. Maybe the only 3000 psi rated radiator hose in existence.

The president of Aeroquip at that time was a gear head, so he used to let me work on the coupe with the technicians at work, he saw the hoses and loved it so we developed the slide over anodized "nuts" with the clamp inside to simulate the screw together aircraft crimp fitting and the rest as they say is history. I still have boxes of hose and fittings from the day.

Anyway now that your all bored with another of my stories of the old days, to cut it we used a strong white tape about 3/4 inch wide similar to what you would wrap a hockey stick with and wrap it very tight, cut in the middle of the tape and leave the tape on the braid.
cutting with a thin high speed cutting wheel (steel) really helps. Like a cut off saw with a thin 12 inch diameter blade.
you might try a die grinder with a thin cutting blade? it would be similar to what we used only much smaller. I have not tried it yet.
we also had the hose clamped in v blocks on both sides of blade when we made the cut. Also, it tends to push the tape outward slowly, so slide the nut on immediately after cutting.
It is possilble and we used to make a braid that is cast onto the hose (smaller than the hose) that does not flare when cut. It actually presses in on the hose. I thought the auto world had switched to that. I guess they lost that art somewhere along the line.
Maybe someone should figure it out again, its not that difficult, but apparently the current makers of inexpensive stainless braided hose do not know that trick or do not have the equipment that will control the braid well enough. sorry I'm rambling again. Must be the drink. ;D

The way I make SS braided lines is to use a big, sharp set of cutters and snip the line in half. It usually takes a few snips to make the cut. Then, there are some frayed SS wires poking around the cut, so I take the cutters and trim the frayed wires down to the bottom. This makes for a clean hose end which I can work into the fitting using my fingers. No tape needed. YMMV, but this works for me.

Edit: By cutters I mean that handheld tools that starts with a "d" and rhyme with "mikes." For some reason this is a bad word and it appears as "d**es."  :dontknow:  When would lesbians even be discussed on this forum?

Thanks for all the help, used a die cutter to cut it, might just leave part of the tape on like most of you said, just get all the rubber dust in the hose, but can flush that out. Might buy cutters if I do more....   Nice to hear some history on these fittings..great way of doing it really, I see how the government pays $200 for a hammer..... awsome but expensive  :D

For cutting the hose, I've always used tape and a hacksaw. The trick with a hacksaw is using two blades, one forward, the other reversed.

I did all the way from back to front w/ Aeroquip 8-AN fittings, fittings goes nicely in.

D O  N O T  U S E XRP fittings!!!! You'll loose your brains, I did while doing a filter line with XRP's.. F****** crappy fittings  :ack:

Oh well, luckily I've been working out in a gym for many many years, had to use all my arms to get those XRP's in, Aeroquips just smoothly by turning and it fetches itself in..
Dementia already from the year...mmmm ???
