Alternate Way of Bending Hardline Tubing

[iS0T0NiX]

I recently purchased the Thermaltake Pacific RL240 D5 Hard Tube Water Cooling Kit, and am planning on bending the tube instead of having straight runs connected via 90 Degree fittings and so forth purely from a cost and point of failure standpoint, and I was wondering if there are alternate ways of bending tubing aside from a heat gun, as i dont have a heatgun and would avoid buying one if possible.for clarification the tubes in the kit are V-Tubler PETG Tube 16mm(5/8") OD and 12mm ID, and i have 2m of it.

 

Cheers!

A hair dryer is your best bet

You can test a hair dryer I guess but I think you will have to hold it very close to the source.

 

On an unrelated note, just thought to let you know that your radiator is aluminium in that kit so please keep an eye for signs of corrosion through mixed metals. Or consider swapping the radiator out for a more standard copper/brass radiator.

why not use soft tubing

HArdline tubing can bend if the cooling water reaches 50°C, which is not really hard ot achieve when you oc and run a 240 rad with low rpm fans

There are alternatives but you will see on you tube, you really want the way that is proven to give the best quality.

Bending pipes is a really old process that crosses several trades. I learnt to bend copper and plastic using a steel spring and a heat gun. Now days the steel spring has been replaced with silicon which is so much better because the spring leaves a spiral pattern. Old guys tell me in the past they filled pipes with sand before heating with a blow torch

why not go with copper tubing and braze all the connections. no leaks. no shitty plastic bending. plus it looks cooler

Glass transition of PETG is about 88 degrees so 50 would not cut it. My PETG is still rock solid at those temperatures.

I remember another guy in the past dipped his PETG + silicon insert into boiling water bath and supposedly had good succes. never tried it myself tjoigh.

i have read i think on this forum where people at least claimed that curved bends can bend themselves once the liquid hits around 50°C

Buy the heat gun after you have all the parts and return it when you are done. That's what I plan to do.

If you have a gas stove that would work too. It's how I did my bends. Just turn the flames low and keep the tube spinning above it around 20cm/8inches.

Theres a few heatguns to bend hardline tubes and honestly i would prefer spending the 15 bucks rather than break a few tubes which will cost the same
