reusing AN fitting

When reusing an AN type Russell hose end ( on an Aeroquip hose) is it needed to cut off the hose end section previously used before re installing the hose end fitting or can the fitting be re-installed back in place where it was removed from?
Reason asking I assembled a hose section and pulled a stupid and forgot to slip a chunk of fire sleeve onto this one that needs to be on there ( as I kick myself for letting the guy talk me into not purchasing the larger size sleeve that would have slipped over the fittings) I now have a hose that needs a fire sleeve on it and the thing won't go on with the ends on.
Thanks-------Robert

You might get away with pulling it apart. The fitting should be reusable - the hose ???. The hose tends to get buggered up internally from the ridges on the fitting. Of course you can cut the hose in the middle and use a union, AN-AN (http://www.jegs.com/p/JEGS/JEGS-AN-R...52560/10002/-1)

When I assembled and repaired Aeroquip hoses for aircraft applications, we were not authorized to put a fitting onto the end of the hose where a fitting had been previously installed. Instead, if we were going to re-use the hose, we had to cut off the portion of the hose end that was in contact with any portion of the old fitting.

Now what I have seen for emergency repairs in the field is slitting the firesleeve length wise and installing that on the hose (kind of like using split wire loom over a wire), sealing the slit on the hose with red RTV. Then slit another piece of firesleeve the same way, and install that over the first piece of firesleeve, positioning the slit on the opposite side from the first slit and seal with red RTV, essentially encapsulating the hose entirely with firesleeve. You wind up with a hose that is thicker and doesn't bend quite as well but it will work. In any event, don't forget to seal the end of the firesleeve with the red RTV where it encircles the fitting to keep fluids from wicking up inside the firesleeve.

Excellent ! I can do that and not have to shorten my hose. That'll keep till I get home (I'm about 1800 miles from home right now and a bit short on tools) Thanks!

Great! Sounds like your situation qualifies as an in-the field, emergency repair. When you get it home, you can peel off the two layers of firesleeve you just put on and then put the right size on for a permanent fix.

Actually, I got kind of stupid lucky. as I went to cut the seam I found it had a double inner folded seam and all I had to do was split the stitching on the outer one and it expanded enough to fit over the hose end. that'll get me home till I can get some more larger firesleeve.
Thanks all.
