Hardline workshop

Recommended Posts

And as a bonus!

 

I have been asked a few times now how i bent my pipe for my SR 2 build,so i decided to do a little walk thru.

The tools you will need are these:

RU8F4.jpg

A Cup of Tea...mine was a milky number to get the juices flowing.

A set of benders...these are for half-hard pipe,not annealed pipe as annealed is thin walled and should be bent by hand.

A Cutter for the chosen OD of your tube

A Ruler

Some tape.

I recommend Rothenberger benders,these are high quality and are worth the extra.

Otherwise,you may have to 'mod' the benders..like this:

The top guide was poorly aligned and needed a bit of work before use.

Poorly aligned guides can distort the tube and put creases down the length of the bend.

So..take a bit of tape to make a base mark.

Place the base mark on the 0 point of the bender.

Line up the guide with the 0 mark.

Make the bend using constant pressure,dont snatch at it,use nice firm and even pressure.

Once you have made your bend,measure the distance from the 0 mark and the outer wall of the bend.

This is the radius measurement,in this case 28mm,remember this as it will allow you to make accurate 90-90 bends to go 180 like this.

To cut the tube to length,use the cutter,rotating the the direction indicated on the tool.

Try to keep everything straight when cutting,the cutter can spiral if its not held 90 to the pipe.

This a basic guide,for any specific info,please comment below.

 

God that chrome rigid tubing looks amazing :P

 

I wonder how it will look in black on a spray-painted-white ASUS sabertooth :huh:

Hey I'm fairly new to watercooling but at work we do alot of stainless steel airline bending.  I am flirting with the idea of doing a rigid build out of stainless steel lines with compression fittings.  My question for you gentlemen is can I use 1/2" OD Stainless Tubing with standard watercooling (Primochill perhaps?) Rigid tube compression fittings?

Wow that seems way to complicated...I think I'll stick to regular tubing for a bit xD

Metal hardline tubes are simple to ben to your needs, alot easier than the Acrylic based hardline tubes/kits.

I'm confused, asked this question a few times, still confused.

What kind of fittings does soft copper need? Any higher risk of leaks?

Thanks.

Exactly the same fittings as acrylic. Tube OD to match the fitting size and thats it.

Can I ask questions in this thread?

I've gotten 3 bent rigid tubes in my build at the moment and I'm worried about "stress" on the tubing.... On all of them I put the tubing into fitting A, and to get it into fitting B I had to move the tubing ever so slightly.... Over time... can it shatter from stress? It's difficult getting it perfect and just not sure if this is common

 

Also could you explain "seating depth" I'm assuming that means how far the tubing is into the fitting, I'm assuming the further in, the better?

Seating depth is exactly that,its the depth that a tube will go into a fitting.

 

A little bit of play is acceptable.

 

Acrylic is not as weak as you may think.

copper should use the same fittings as pteg so as long as the fitting and the copper has the same od.

For your rigid tubing, what was the ID/OD that you used? Is there a preferred size and does it make a difference?

If you're doing hardline don't worry about id the fitings only hold onto the tuberings outside unlike soft tubeing that has to fit over a barb.

Primochill jumped on that bandwagon because MNPC said it was okay......with NO long term testing at all.

The same Primochill that brought some of the worst tube ever to market...

 

Its untested for long term use for our application,you may be the guinea pig if you wish,I will not recommend it until there is.

I have a PETG system up and running for over a year now. 0 leaks, 0 issues with it at all. I have UV lights in my rig, and my white tubes are exactly the same as when I first installed them. My machine is on pretty much 24/7 as well.

Rigid tubing related; going to be doing carbon fiber tubing soon. I just can't decide on glossy or matte. I'm asking tons of people on tons of places for opinions.

So, which do you guys think?

any tips for getting the silicon in the tube ive tried oil it always sucks trying to get it in.

Especially bad if you need to bend the middle of a tube.

when bending rigid tube ( its my first time) i just managed to make my first bend without wrinkles or anything, but i did notice that in the curve of the bend the tube is flatter on 1 axis, does it happens because it's still too cold or because i overheated?

 

this is using EKWB PETG 10/12mm tubes, i noticed that when heating the tube the part being heated expands a lot and when i make the bend the diameter of the tube is greater in the bend 14,20mm in 1 axis and 12,10mm in the other.

 

im using the EKWB hardline kit silicone insert, i tried bending by hand or by using the XSPC bend tool with the same result.

 

 

any tips for this issues? pointers?

Heat the part that stretches more than the compressing side. You will still tend to get a bit of flat but its not to bad. Also heat up a larger area on the part that stretches.
