Hardline question

[blinky1041]

Does anyone know how those hardline setups that don't have any fittings are put together? Thanks.

Hardlines without fittings?? I dont think there is such a thing unless you are talking about welding them. I make ss hardlines, and have never seen any that didnt require fittings.

pressure fittings...

is this what your talking about?

[MANN]

If those ^^^ are what you are talking about then they do have fittings. Those are swegelock (Im sure I misspelled that) fittings that are 1/8"npt to 1/4"cpt. with 1/4" alum tubing (alum is rated for 3-4 thousand psi, and the steel is rated to 10300 psi.

I have been wanting to go harline for a while, but I can't figure out how to bend the tubing. How do you do it?

[MANN]

a tubing bender. Its a speciality tool that you can order from swegelock. pm me and Ill try to help you out

I know, I know!!

If you are referring to the one like Doc Nickle made a while back that looks like the hardline just emerges from one port and goes into another with no fittings or elbows then I know the answer!

I had asked about it as well and Doc said he used 1/8 npt plugs and dilled them out to fit the hardline into them. Then, he soldered the drilled out fittings onto the ends of the already bent hardline and installed it. It will require dissasembly of your marker to get it off though.

I have use another method that doesn't use the type of compression fittings shown in the picture above. Use macroline fittings and 1/4" SS tubing and the tubing should slide perfectly into the macroline fittings. I have used this method and it works and it is easier to dissasemble your marker.

Thanks

Try swagelok. You can also get stainless tubing that is much more rugged, but you can still use the hand bender on it.

That sounds about right. I think we got ours for 80ish

How did you get it to seal? I have many different thickness of ss tubing, and have tried what you said, however always had leaks. I have used both brass, nickel, and ss microline fittings.

Hs2000 pm me I can try to help you out on the bend.

Thanks, I will, although I don't have the money to do anything right now.

If you already have the parts I will bend for free. If you need the parts Ill hook you up.

It should be just a standard 1/4" OD line. I am using a 316 SS line with 1/4" OD and .032" walls. I am also using just standard macroline fittings and it slides right in. The orings inside of the fittings act as your seal. You may want to make sure that either your line is long enough to seal on these orings or that your orings are still good.
