PETG tubing for watercooling, how much can I bend this safely?

[Guy_7_]

I am wondering how strong PETG tubing is when heat bending, I was thinking of bending PETG tubing into spiral coils for my water cooling build due to aesthetics over anything else.

How tight can you bend it without risk?

 

[Mr Kagouris]

With a rubber insert inside the tube you could pretty much bend the whole length of it any way you want. That said, good fracking luck making a spiral coil with PETG! (Or any hard tube for that matter)

A spiral coil would also create a lot of resistance so you may be looking at needing dual DDC pumps (depending on how big the coil would be).

Cheers for the reply!

Would I not even be able to do a very loose one? even if it was only like 3 rings going up loosely I'm sure it would still satisfy my desire for coils

Also if i did somehow manage it would it be better suited below the pump/reservoir rather than above it to help with flow/pressure?

I had thought of doing it with flexible tubing but was thinking it would try to uncoil itself over time and end up pulling off a tube or something, never used it before so unsure how springy it is.

Position in the loop doesn't matter.

If you think you can actually make the coil go ahead. PETG tubes are pretty cheap so you have headroom for trying.

That is true I suppose! I think I shall try it out at some point, although I'm quite concerned for my plans now hah, would be cool if i could pull it off though and would look sweet with uv green liquid running through a few coils

If you pull it off and finish the build be sure to post it in the Tom's Hardware Member Systems thread here:

And heck, even if you don't pull it off and just make a regular custom loop, post it regardless! We'd love to see your completed system!

Shall do! this would be my first custom loop so will be interesting for me at least, won't be able to do it for a while though as i think i shall have to find a new case as, my spec 03 is a tad too small for what I want to do but I may try it in there first to save me some ££
