Thread: Stainless hose

Tweet

Maybe it's because I'm using Summit hose and Earl's fittings, but I cannot get the ferrule over the hose. I've taped the hose and cut it with a 32-tooth hacksaw. I've taped it and cut it with a cutoff wheel. I clip the ends. As soon as I take the tape off, the braid expands, and I can't get it inserted. Any hints?

Holley has the Earls catalog on line - all except the instructions.

Here is a link to instructions

You should be able to get the ferrule over the hose before you cut
the hose to length.....it takes a motion like you are screwing the ferrule on.

Also, I have found that the hacksaw is the worst. A cutoff wheel on a dremel tool makes a better cut....cuts right thru the tape.

The wire braid hurts when it sticks in your finger, doesnt it?
-4 and -6 are the hardest, bigger is easier.

Thanks for the instructions. That's what I remembered. However, I didn't remember it being this tough.

I'm using -8 hose, and it's no fun either. I went to a cut-off wheel on a mini die grinder, and that worked . . . pretty much. Trying to stuff all that stainless wire inside with your thumbnails basically sucks.

I haven't used that hose in a long time but if I remember right I came up with a way to do it. I used a small hose clamp to hold the wire to get it started then removed it and finished from there?? I think thats how I did it hope this helps

I use less than 2 wraps of masking tape (more than 1 and less than 2) and cut the hose with a cutoff wheel. I do not remove the tape before I put the ferrule on. I twist the ferrule only in one direction, usually clockwise looking at the end of the hose. The masking tape does not affect the joint so you can leave it on if you want. I oil the end of the hose to insert the fitting.

Duct tape is too thick to slip the ferrule over.

The thin cutoff wheels throw a lot of stainless hose debris so wear safety glasses and a face shield.....otherwise you will have stainless wiskers.

Not sure where I saw it but I think one of the carb companys came out with a fixture for doing that....... seems like it was Holley.

The best tool for cutting is available in the summit catalog: a pair of cutters ( looks like bolt cutters ) with curved blades (( )) and they really make a clean cut. I use electrical tape, and run a double wrap around the cut, then cut through the center of the tape. I leave the tape in place, and spin the ferrule over the hose. ( just as the fellow already posted )

I use a cutoff wheel as Robot does.
Cut slow and the ends come out nice.

I've had good luck without the masking tape on, but it looks like a good idea that could make life easier.

There may be additional information about assembly at airplane sites.
Search for "Experimental Aircraft" or "Homebuilt Aircraft."

One thing I've found that helps is to use a small screwdriver to tuck the errant strands of stainless wire into the ferrule when you're starting the braided hose insertion into the ferrule.
Especially so with #4.

Bigger the stuff is, the easier it gets.
#8 is easy and #10 is a pleasure.

Using Never-Seize on the threads is a help.

Or you could make friends with your local Custom Hose Shop. A cold 6 pak of MGD usually works good.

I can identify 43 individual braided hoses on our rock crawler....so 86 hose ends.....it would take more than a six pak of MGD for the hose guy to do all of those!!! I always do the first end before cutting the hose to length so I get the first end done before I commit to the length.....the hose tends to get shorter as you recut each time you screw up the braid.......

I bought a set of the new hose fixtures that supposedly help but doing it the manual way is faster most of the time.

I may have got lucky ,..but I used the tin snips and it cut like butter,the rubber on the inside ,keeps the braid from kinkin ,collapsing like you would think.

Ouch . . . ow . . . oooh . . . ouch . . . ow . . . got one. Ouch . . . darn . . . ow . . .ouch . . . dangit . . . got two . . . half done.

Actually, I'd buy the cutter, but with only four to six to do, it's not worth the cost. Also, I suspect that the Summit imported hose is not quite as easy to work with as real Earl's hose.

The tape process seems to work OK, but it takes a rigid tape like masking tape. The electrical tape stretches due to the heat of the cutter.

A small correction . . . when I said I don't use masking tape, I meant during assembly.
I do use it when cutting.

I'm guessing your Summit imported hose comment is right on.

I tried to use some Russel hose about 12 years back.
Crappy stuff and it went into the trash and onto my, "never buy that stuff again...."

I've done well with both Earl's and Aeroquip hose and fittings.

Sometimes it takes a few tries to get it right . . . Seven tries to get two. Of course, if it were baseball, I'm batting 286. I think the difference between the Summit hose and the Earls hose is that Earls bonds the braid to the liner. Summit may trie, but it ain't workin'.

I use Aeroquip.
