A question to tube bending

[peak]

When looking at the Case Mod gallery, I found tubes were bended into 180 degree curve, i tried but all failed. How to do that?

The tubing needs to be thick walled (like 1/2" ID, 3/4" OD), or it needs to be supported by anti-kink coils like Swiftech SmartCoils.

Do you mean for water cooling? You can buy 90 degree elbow fittings for tube to tube as well as 45 and 90 degree fittings.

YeaP, i mean water cooling, i tried Tygon 3603 Tubing 1/2" ID 3/4" OD, failed. The anti-kink coils is a must? i mean how about the heat retreatment.
Check this out, Does he use the coils?

Not sure what tubing he's using. Some are more flexible than others, but each tubing has it's limit of what it can bend in a certain radius.

ok, thanks.

When I knew I had a tight bend to make, I heated up the tubing a bit and installed it warm. It's alot more flexable and can bend without kinking.

Usually if I had to make a sharp turn I'd assist it with choosing an appropriate fitting.

Yup. Put it in some almost boiling water, then slip it on. Gonna be hard on your hands, so light gloves will help.

I try it later on, thanks all.

Or buy good tubing. I have feser tubing and I can bend it like that picture above with no fear of kinking.

If you can get a flexible coil spring to fit inside the tube to stop it collapsing.

Bend the tube to the desired angle and then put it into warm water and then while it is still hot put it in a bucket of cold water and then repeat a few times.Then when you have the desired bend in the tubing, remove the coil spring and install the tube.

EDIT: Article I found on the subject that was linked from another forum.

tygon is good tubing, used it for years never an issue. he just needs to soak it for 180's in tight situations.

I've seen a lot of kinking issues with Tygon though. Thats the only reason I didn't save money and by that brand. I'm for sure not saying its bad tubing; i'm just saying there are better options out there.

I don't think I'd want to add a coil to the 'inside' of my tubing. I'm not sure what coils are made out of (plastic?) but adding another material inside the loop might not be the best idea.

I have some tygon, and noticed it was somewhat kink prone at first, but a few months later after keeping it warmed up in a bent shape, I can now do some pretty tight curves without kinking similar to the picture above.

New tubing Vs old tubing is noticeably different.

Did you read the link I posted ?

The coil is made from metal and is only used to help form the tube into shape.It stops the tubing collapsing while you are heating it up and cooling it down.
It then is removed before the tube is put into the loop.

ugh.. anti kink coils.. couple that with an externaly mounted rad, cluttered cables, hydrix, and a uv ccfl.. so passe'



I find 7/16 ID 5/8 OD bend better than the 1/2id 3/4od.. but then again, maybe the fesser 1/2id I used one time was crap

and judging from this pic, looks like hes using a 7/16 ID 5/8 OD. They can bend that way without fugly anti kink coils..

 

[oily_17]

ugh.. anti kink coils..

I am not talking about anti-kink coils, read the link I posted, and you will see that the coil spring I am talking about fits inside the tube to help with forming tight bends.It is then removed before you install the tubing in your system.

Sorry I did not notice that.
