Two metal hydraulic lines (3/8 od), I need to couple them together. Can I use regular brass feruled compression fittings? If not, what type of fitting can I use? Not sure if they are up to
the high temperature changes of a hydraulic line.

Dean

Ps I need to be able to unbolt the couplings, and bypass the winch if necessary.

Are the tubes flared or can you flare them? I would suggest flaring them and using inverted flare male-male brass coupler.
I don't like the ide of compression fittings, but to each their own.

Dean, I sent you a response on the Yahoo Group.

For one, I guess I need to know what type of tubes; Flex or metal.

Metal Tubes: To splice in (so to speak),

#1 Cut tube length out.
#2 Flare both cut ends. Yes this requires a tool and I think the general flare for aluminium is 37 degrees.
#3 Then make your connections with the same type of tube material with required sleeves, unions, and tube nuts. Dean, I cannot stress how important using the same material is in regards to contamination and corrsion. While connecting your tubes, use the hyd fluid to lube the threaded connections. Standard torque is good, but once you factor in road vibration, I would automatically add 10%.

Flexible:

#1 Cut into hose at desired location.
#2 Clean off any frayed areas and area of your cut.
#3 Place hose in vise and attach something called a Screw Socket. Lubricate threads once complete.
#4 Into the Screw Socket; Screw in the new nipple fitting or whatever you decide to go with for the union.

Hope this helps, if you have issues, we can talk tommorrow. Just email me at Boeing.

Paul, Jason

Thanks for the info. The tubes are stiff metal, not sure what they are made of but they are not flexible. Look like brake pipes to me.

Ok so I'll pick up a flaring tool. Jason I presume you mean a regular flare, not an inverted flare, becasue I don't know any tool that can make that type. Might give you a call tomorrow Paul.

Dean,

Find a Hydraulics place! Just go in there and be like I want this to go into this and they will hook you up. Any place that sells construction equipment will know where one is and it is not like this stuff is expensive.

Stiff Metal Eh?

I guarantee that they are aluminum which will be easier to work with and make a "leak proof" connection.

If you are talking about the oil or trans cooler lines - they are 1/2" OD and to connect two you'll need some high-pressure STEEL hydraulic compression fittings. These do not require the lines to be flared and go on fairly quickly. To install them correctly, you'll need to remove the lines from the truck and do the work on the bench.

As mentioned above - a local hydraulic shop will have these.

Dean - sorry, just saw your ref to 3/8" - same applies though.

Dean,

You are not going to tap in to the oil or trans cooler lines to run that Mile Marker are you? I thought you were tapping into the power steering lines. Now, I am confused.....

Bill: Nope. The high pressure power steering line runs across behind the radiator and back to the steering box, for cooling. Its a 3/8 tube. I'm not talking about the trans oil cooler:-)

Dean - saw that after I had posted - same type of fitting applies though regardless of size. E-mail me off list if you cannot find locally.

Good Luck

Bill

Paul, I meant to say thanks earlier for your detailed instruction. If as you say the (5/16") pipes are made of aluminum, what connector material can I use? Anyway I'm pretty sure they are s. steel. Of course, once I cut a piece out, I'll be able to tell:-)

Hey Dean,

Depending on what fittings you go with and type of material, you will use standard MS or AN hardware. I am not sure what LR uses. Follow the line you are tapping into and look for an identifiction code.

If for some reason it is AN, then I can help. But if it's MS, you had better send Bill an email.
