Greetings Forum Chums....Bought some stainless 1/8 rod to repair the oil line on the 861....I have flared a lot of copper.....but Lord help me...The stainless is not going well....How much
angst would it cause some of you if you were faced with the issue...and considered copper....I have 1/8th copper.....and it is starting to look really good!!....Thoughts, comments...bad ideas???

You said rod - I assume you meant tube. Stainless tube is tougher to flare than carbon steel and a lot tougher than copper. What sort of flare are you trying to make?

There's a couple of reasons that the notoriously tight Henry Ford didn't use copper oil or fuel lines: copper will get brittle & crack over time & it is prone to vibration leaks.

I'd buy the proper flaring tool & a custom made line before I'd use copper.

That being said......

When I was a poor HS student making $1.25 an hour, I put an external oil line on my 235 6 cyl. Chevy. It was always leaking. Neighbor told me to get a longer line & put a loop in it. Stopped the leak.

I don't know where your line is broken, but if it is broke in an
accessible spot compression fittings may work.
I repaired the line to the gauge on my Jubilee that way.
Obviously won't help a line that is plain rusted out.

I never approve of overkill.
Use OEM type steel tubing and it will flare much easier.

You need to do a double flare like brake lines. A single flare is cracking for you ,right?

Reply to all.....Didn't give enough info Chums...
My bad....Here is the deal....could not find OEM 1/8th inch tube or brake line...anywhere...period..does not mean it does not exist anymore...But I could not find it...hence the stainless that I did find...used a conventional flaring kit to no avail.... the stainless is too tough....compression fittings a possibility if I can find them....I did think of those Royse....1/8th is going Bye Bye in general...new flairing tools only go down to 3/16ths.....is there another tool flaring tool for stainles??

Ed Douglas · Dec 6, 2014

No....this is for an old half vast repair....hose clamps and gas line and a foot of the original line gone....so uncivilized!!

You will not find much for 1/8" steel tubing. Mostly scientific instrumentation applications and very pricey. McMaster has JIC compression fittings for 1/8" stainless stel but you will need an adapter to get to the inverted flare on yoour tractor.

What's wrong with using a little larger tube size - 3/16"? BundyWeld brake line is very economical and easy to work with.

At the risk of removing all doubt as to my mental acumen.....The fittings that go into the block and gauge are for the original 1/8th line...would 3/16th fit.....I assumed not.....do I ere in my assessment?? do I drill out the flare nuts?
Easy enough I guess...

They make adapters for that sort of thing :shock:

Should be straight forward to convert to a larger tube size. I'm guessing the block and gauge fittings are just 1/8" tube adapters - replace with same type but for larger tube.

That is the problem my friend...not finding the fittings or adapters.....I will keep looking!
Many Thanks!

I bought a Rigid flare kit from Homedepot and it works better than my Snapon or Mac! I flare stainless 3/16 and 1/4 all the time.

I thought the oil gauge lines are 1/8pipe fitting using 3/16 line - that's what I put on my 9ns anyhow.... The aftermarket Sunpro gauges use 1/8" copper or plastic line but connect with compression fittings rather than a flare.
