I need a suction Line !!!!

[Mr. Manka]

hello all,

I am in need of a suction line to finish up my single stage.
I know chilly1 has them, but I really dont want to bother him as he is really swamped.

Could you guys give me the names of people that sell 3/8 suction lines with brazed copper ends.

thanks

Rich

I think, that Jinu117 or Runmc can do that for you ;)

[Revv23]

yeah under-the-ice is runmc's website iirc, google it.

[ak_47_boy]

you could go to home depot and get yourself a yellow flex gas line, they are abut $20 and will work great, you can use brass fitting to go to a flare.

Pressure rating of that is? :)

I wouldn't trust those lines, I saw them in Home Depot and I remember passing them up because I didn't trust the connection. The ones I saw also were only 18" or so, not nearly long enough.

no...
be safe

[eshbach]

you can use the yellow SS hoses at home depot if you're going to braze copper ends on... but it would cost you more for the braze alone (45T) than it would to buy one from under-the-ice.

[chilly1]

I have new bronze flex lines that are stronger than stainless less prone to breakage and can be brazed with the same materials you use for copper...

[Carlz0r]

Those look pretty cool chilly.

[Jort]

any braid for those? i don't like flex's without em :)

[n00b 0f l337]

Is it cheaper or easier to get in small quantities?

[ak_47_boy]

The yellow gas line i got is 48" long and feels alot heavier than the yellow jacket i flex line i got. Its not as flexable but if you are not taking it on and off motherboards when benching crap it doesent realy matter. The flare fittings on the end are frickin heavy duty, they could handle 400psi easy no leak. Oh and if you bend it back and forth too much they will leak, again unless your benching loads of motherboards every day and bending the thing to hell you are not gona have any problems. Look for brass fittings also, you can get a strait 1.5" piece that you can braze to your evaparator then screw your suction line onto. I dont think its a good idea to braze onto a stainless flex line, when you heat and coo stainless it becomes brittle and that is not good. And you dont have to get any expensive braze :)

[n00b 0f l337]

Tons and tons of people braze to stainless steel flex line.

[[XC] mysticmerlin]

RunMc's are done and tested so why not just put down $30 and be done with it? JMO

ya i know but heating up and cooling stainless weakins it... shoudent matter but in the strictist sence...

[TheBender]

Why dont you guys think a gas line from Homedepot is bad? The $28.50 flex line at Under the Ice is a gas line with copper ends brazed to it. For $28.50 its an awsome deal unless you just want the DIY factor.

Chilly where do you get that bronze flex line material?

Check out the pic its stainless brazed to copper

[n00b 0f l337]

Yeah Runmc's stuff is good, flux + 45% is wonderful.
The homedeopt stuff you still gotta get the paint off of too.

[TheBender]

What do you all think about these? I would chop the fittings off and braze copper tubing on with high silver content braze rod. The price is right!

[n00b 0f l337]

Only 1/4" ID.

[TheBender]

Only 1/4" ID.

They have a size bigger available for the same price. My 3/8" copper tubing is about 1/4" ID as well :confused:

[n00b 0f l337]

Just purchased, geuss I'll be the guinea.

[TheBender]

I hope it goes well for you. I am about 95% certain those lines will work just fine. I measured my 3/8" OD copper tubing and it is indeed 1/4" ID. I used a micrometer and it read 0.25" Is 1/4" going to be bad for my system?

[jinu117]

Basically. larger diameter has significantly lower operational pressure rating... And the bronze one, chilly, is rated for not so high PSI without braid on it... I am not sure why you say it is stronger?

[n00b 0f l337]

More similar expansion contraction rates I geuss that could be stronger based on the situation.

Doubt it... specification tells otherwise... do quick search around single braided flexible metal hose and find brozne braided vs stainless steel braided. About 60-100% lesser rating.

I thought it was $70US...

The homedeopt stuff you still gotta get the paint off of too.
Why??

Also i dont think the word "bronze" and "flex" go together... from my expereiance i know for a fact bronze bushings cant be bent at all, if you put them in a vise to cut them they will crack. Bronze is a very wierd metal, its soft but doesent wear, its soft but isnt maluble...

edit: they are $28, that is a better deal than home depot! but still not as fast to get.

[Blaster]

guess im the only one using copper flex lines :D

It's the pressure it can withstand is one of the main concerns, natural gas and propane have there pressure measured in ounces per square inch on the low pressure side of the regulator.

even though a propane tank may have 120 psi tank pressure, the secondary pressure (after a regulator) is only ounces per square inch.

You need to be aware of the application, most stuff sold at DIY places if for the hook up of appliences or the low pressure side. And is primarly designed for only ounces of pressure.

[ak_47_boy]

Natural gas in houses is only about 2psi, but those pipes could withstand 400psi+. They are overbuilt exponentially for odvious reasons, there is no way one of those lines are going to burst. If someone has some spare money you could cap it at one end, and put a guage at the other and fill the line with dice to see when it ruptures. Use binoculars to read the guage.

[best [486]]

i have tested mine to 200psi then got scared because i was just filling it with an nitrogen tank and didnt want to waste 20$ i should get one then use my dad's shop's nitrogen tank to test it to burst in a trash can filled with water

and where do you get corrigated copper tubing? [not the water heater water lines]

[chilly1]

I use Bronze tubing rated at 90 psi with out brade and 800 psi with braid.... comes from tubing supply back east..

[best [486]]

and bronze bushings do wear, if youve had one spin in a sheetmetal bushing holder they go right thrugh

[ak_47_boy]

If you have the proper size harened shaft and a high quality bronze bushing it could outlive a bearing. I think they use the same idea in engines, alumium bore to steel piston or in the old days steel sleve to aluminum piston.
