View Full Version : DIY: Putting together an AN stainless steel braided hose

A forum member asked me to guide him through putting together a braided hose. Instead of sending it to his PM, I figured post it public so others who don't know how to do it can also learn. There are different ways to do it, but this is how I do mine.

Tools and supplies:

-Power drill with "metal" cut off wheel or whatever you are going to use to cut your hose to size
-SS braided hose
-Hose end fitting
-Phillips and flat head screwdriver

It is rather easy to do, but you may goof your first time around. But I will post pointers to assist in making that not happen. For starters, watch out for the split ends. It is almost unavoidable to get pricked. So, just be ready. And try not to make the ends fray. Keep the SS sheathing as close and seated flush to the inner rubber hose as possible. Try not to let the strands separate and open up on the ends. So, let's start...

First you need to cut your hose to proper size. When you order your SS hose, it comes as one solid length of however long you ordered it. So, cut off only what you need per cut. What I do is install the AN side of the hose end fitting where it needs to go, route the hose, mark it, and cut it. After that, you want to use your snips to cut off the ends of the SS sheathing to make the end of the hose flush. Reason for this is you don't want any of that getting caught in the threads. It will mess the hose end fitting up as you are tightening it, and it will be basically ruined. Ask me how I know!

I had spare hoses and fittings laying around, so I used this 6 an assembly for demonstration.


Take the hose end fitting apart. And please, don't buy ebay junk. I personally use Jegs or Summit Racing pieces, as they are quality at a decent price. But then you have others like Earl's, Russel, etc. Those are all good quality. Anyways...hose end fitting apart.


This is the hardest part of the ordeal. Getting one end of the hose end fitting to slip over the SS braided hose. I have a tactic. I basically coax it in. You can't go straight in, as the SS sheathing will basically fight against you. Don't try to fight it, it's a losing battle. Don't even start. Instead, seat only a portion in at an angle, slipping the SS strands in. Then, use a flat head screwdriver and work your way around the rest of the hose pushing the strands in with the hose. It works. Here it is completely in.


Then twist the hose end fitting down till it hits the built in stop of the hose end fitting.


Now if you look inside the fitting, the ID (inner diameter) or bore of the hose may have some waves to it. Simply take a Philips head screwdriver and fix it in a circular motion once the screwdriver is in the hose.


And all is good!!!


Last step, just thread the other end of the hose end fitting into that. I suggest you hold the hose while you first thread down the other end of the fitting, and apply force against the other end of the hose end fitting as you are torquing it down by hand. This will ensure that things are held tight together.


Use your wrenches to torque it down fully when you can no longer torque it with your fingers, and you are done. And that's it.

[up] to you for putting this together

I've read that you need to use anodized wrenches so as not to screw up the AN fittings, is that true?

There's designated AN wrenches, but I've never used them.

Nice write up Mitch [up]

The hose frays MUCH less if you wrap the area you're about to cut with tape first. Then you pull the tape off right before you stick it into the fitting.

That is the best way to keep from scratching it if using aluminum fittings, they even make adjustable aluminum wrenches. Other options are to put something over the metal surfaces or use tolls that have a coating.

BTW sometimes one side of the fitting isn't actually a AN size, some times it is just the end piece that is so 2 standard AN wrenches might not work. So basically the AN wrench might only fit on the end that threads onto an actual AN adapter fitting and not on the hose end that you are trying to put together which is one of the reasons they offer adjustable AN wrenches.
