Hardline question

[blinky1041]

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

[MANN]

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.

[Chronobreak]

pressure fittings...

is this what your talking about?

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

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.

Where can I get a this speciality tool? I tried googling "swegelock" with no results.
Thanks

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

I think this is 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.

[MANN]

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.

You kids are crazy...

I don't know what story WWA gave you and perhaps he does bend his own hardlines, but...




The CCI Phantom comes stock with the exact same setup (about $15-20 to buy it from any CCI dealer) consisting of two compression fittings and the bent tubing. The fittings connect with a rubber grommet vice a hard seal like you would see on hydraulics, etc. It gives a little more play which is important if you're carrying CO2 and you have to deal with compression/expansion of the tubing.

I love the no-hassle lines on my Phantoms but I would not put one on a 'mag for the reason that it precludes easy removal of the valve. SS braided with a quick disconnect for me.


If you go the route of buying a CCI hardline kit, note that you may need to trim it down to fit on a 'mag, depending on what type of vert. ASA you're using. Tubing cutter for that works just peachy.

Good luck.

[hs2000]

Where can I get some 1/4" stainless hardline (the kind used on phantoms)? I've got everything I need except that. I bought some 3/8" stainless from palmers,

thinking that it would work, but it doesn't. I can't find any where that has it.
Thanks

I am not sure of the OD of the tubing used on Phantoms, but I had to purchase my 1/4" SS tubing from a local metal supply shop. You can actually find it on Ebay and it seems to be a better price than what I paid for mine at a local shop.

You meen like this? how do you know it can hold the pressure?

[MANN]

look it up by knowing what type of stainless, and the thickness. I have 316 thick wall, and it can hold 10300 psi.

[Walrus]

That should work just fine. I used a .032 wall 316 annealed tubing and it worked fine. If you feel up to the challenge you can figure out how much pressure it will hold here:

^^ i wouldnt suggest bending it by hand because if it doesnt bend just right it will have a weak point and blow out easily.

you might be able to do the hard line and still have a disconect ability if u put a QD inbetween the hardline fitting and the valve some how, such as= valve->90* fitting->QD->hardline fitting->hardline

-matt

[MANN]

The fittings will seal 90 % of the time with just finger tight. They are a little hard to get the valve in and out, but once you figure out the "tricks" it is very easy.

[Walrus]

If you go with my suggestion which is using 1/4" SS line and macro fittings, then you have the easiest setup and you can still field strip it by just pulling it apart. It functions exactly the same as macroline setups, but instead of using plastic macro tubing, you are using a stainless steel tube. Works great, its easy, and get the job done! ;)
