Clutch Line wanted

[Old Yeller]

I'm looking for the line running from your master to the external slave clutch cylinders. Late YJ's and all TJ's were set up like this and will work. You would NEVER guess how much the dealer wanted.

$406.00. I laughed in his ear without even meaning to lol. Its either get a used one, or maby see if a hydraulic shop can hook me up possibly. Its partially steel, converting to a plastic line.

Who has one?

$406 gets you whole setup doesn't it? master, slave and tube sold as 1 part number?

If you just have a bad end on the tube you can do this, or you could use a compression fitting and use brake tubing.

I have the PA slave (hydraulic cylinder) on the Jeepster, been there 3-4 years. It's actually about 15 bucks, they changed suppliers. I don't have the plastic pipe though, I have steel.

The TJ's and XJ's tubing is different, XJ comes out of the top of the master and the TJ out the bottom. Not sure on the YJ's.

$406! lolerz

Thats a negative on the whole setup. I've seen those for sale online, but this was just for the line.

Well, mine is a YJ, and it comes out the top of the master. I basically assumed YJs and TJ's were the same, but I guess not.

Will a compression fitting work to join the plastic line to a steel line? The top portion is essentially brake line, but it is plastic where it enters the slave, so it would need to join plastic to steel at some point. If this would work, I would just cut back past the broken section of plastic, and have a longer steel portion.

compression fitting should work. I'm watching closely!

i'll probably be right on your heels doing this to Al's XJ.

(Which btw, has the tube at the master coming out the top)

What size is the plastic tubing, ID and OD?

I think a compresion fitting for plastic line has a sleeve inside to keep the tubing from crushing when it is tightened. If you use a regular compression fitting for steel lines, I think you would have to slide a piece of steel tubing inside the plastic so it won't crush.

[Old Yeller]

Well, mine has a compression fitting down near the slave. However, it joins two sections of plastic line together, and I do not believe it is like this stock.

That site has a decent overview of compression fittions ( Im a google whore). As long as I get the right size fittings I should be able to join the two. I'll bring my caliper home from work tomorrow lol.

PS, this is quickly turning into tech lol.

I wonder if the plastic line foe air lines on trucks would work , it has the steel insert that goes in the end ,the ones i have here are like that . Not sure what the thread was though .... might have been 1/4"ntp. if you had a piece of line you could probably use fittings to match your slave.

I wouldn't think so. That stuff is only rated for air pressure, (prob 100psi working range), and the brake fluid would probably eat it. Just the coolant at work eats it, and its not even corrosive. We are always blowing those blue air lines if they get a lot of coolant residue on them.

Wonder what kind of pressure the clutch line sees?

[dan]

synflex air lines. no, I wouldn't use it. Like Jan said, it is only rated for air pressure, which generally doesn't go over 130 psi on a truck.

I just did a little googling of my own though, and you could try to find "synflex type 1300" it is a metal/plastic composite. aluminum inner layer, with the plastic layer outside. still has the same inner and outer dimensions of regular synflex, and it much stronger, and chemical resistant.

[dan]

another fact is that the regular synflex truck air brake hose has minimum burst ratings of between 1,000 and 1,200 psi.
how much pressure from a clutch master cylinder?
the other thing to be concerned with is what is close enough to melt it if you use it.

Melting is not a factor since the original is just plastic with a wrap of material where it passes by the exhaust and that could be reused.

Compression fittings are also used on hydraulic systems, so the right ones will take a lot of pressure, at least 1000 psi.

I did find one Tube to Tube Union in my pile that is for 3/8" OD tubing. The tubing support measures 0.230 inches, so it is for 1/4" ID. It is Anderson Barrows part no BP962-P, if this will work for you.

If not, then like your google link, just put a support tube inside the plastic tubing, and use a regular compression fitting to join to the steel line.

I do have a few other fittings here for 1/8ID and 1/4OD plastic lines, but no 5/16

i have a couple complete systems here one is bran new i mentioned them to jan but i have not been to the city they are both external im not sure if they came off of yj,s or cherokees i would take 50.00 a peice may be hawkes can get them to the city shoot me your phone #if your interested things change here every 5 mins

[Creepy]

Well I'll take first dibs on the newest one. pm'd my #. thx.
