Shopping list for hard tubing (switching from soft tubing)

[marknicholson23]

Hi there,

I'm wanting to move from soft tubing to hard tubing in my custom loop and wanting to make sure I've got a few things correct before buying the parts. I'm wanting to buy off Overclockers UK website preferably and use Bitspower fittings in matte black and PETG tubing.

First Question
What is the correct size tubing for the Bitspower standard G1/4 fittings as there are 4 different hard tubing sizes and I'm not sure which is the correct one for the G1/4 fittings? The thing throwing me is the Bitspower sizes are shown in inches and the hard tubing in mm and I'm about 60% sure I've got the correct size but want to confirm this before moving forward. My thinking at the moment is this is the correct size PETG for the Bitspower fittings?

Second Question
How much length of PETG should I buy when it's my first go at using hard tubing and bending PETG?

Shopping List So Far

Hard Tube: 3 x https://www.overclockers.co.uk/bitspower-none-chamfer-petg-link-tube-od16mm-1m-wc-65u-bp.html

The last part is my fittings. I'm thinking the following so far:
Res-GPU: 1 x 90 degree rotary, 1 x straight compression fitting
GPU-CPU: 2 x straight compression fitting
CPU-Rad: 2 x straight compression fitting
Rad-Res: 3 x 90 degree rotary

Not sure how much this will help but here is an image of my rig at the moment. https://imgur.com/a/5DuaRic

I'm thinking 3 x 90 degree rotary for the Rad-Res as going out the top of the right side of the res with the 2x 90 degrees there to make the tubing the right distance to line up with a 90-degree fitting going into the right side of the res at the bottom right-hand side.

Any help with this would be greatly appreciated.

G1/4 is the threading. Most stuff has G1/4 threads. The tubes size is 2 numbers, the interior wall diameter size and the other wall diameter size. Just get the correct fittings for your tube.

That's what I'm wanting help to find. The Bitspower fittings on Overclockers don't seem to say the outer dimension for the tube.
