How To Measure: Simplifying Complex Bends With Hard Tubing - PC Water Cooling

Great technique for Beginner's. Great video.

Are you heating the tubes on the table?

Why not marking the middle of the 90° bend and use a bending tool? 🤔

insert a wetted, Si mandrel into the tube BEFORE you heat/bend the tube. your technique alters (“squares”) the outer radius of the bend section, resulting in a kinked section. results in a pressure increase and flow restriction. not super important at these H2O pressures and Q (flow rate); however, the pressure increase become significant as the number of bends increases. essentially, momentum and Q changes in your system. look into EKWB bending blocks (acetal matl) for best practices.

You can explain this much much easier and also recopmend bending form tools that have arrow markings making precise measurement much eaier and makes bends perfect. Also to anyone: use sharpiea to mark your mrasurements and just wipe it off with alcohol after it wipes right off

I'm not sure if you have this information but this appears be similar. Where 1/2 inch electrical conduit is concerned, inorder to make a 90° bend, you have to add 6 inches from the total length desired and make the bend from that point. Meaning that if you need a 36 inch run of electrical conduit with a ninety degree bend at that 36 inch mark, you would add 6 inches from the desired length and begin the bend at this extended point. This is because the curve of the 90° bend takes up the 6 inch slack, and you ultimately end up with a 36 inch 90° bend. I assume the same is true for bending acrylic cooling pipe. However, the takeup slack must be a different length. Do you happen to know what that is? This would be helpful instead of trying to make estimations based on static measurements, you could simply add the required length to accommodate for the desired bend.

Should have watched that before fucking up two tubes

Hi! Just droping huge thank you! I'm doing a custom loop for the first time and holy this video was so helpful. Before I was using specialty tools because I thought that's the only way I can get clean bends. Turns out freaking hands and a ruler give literally the same result. With bending tools I already crewed my 4 bend tube three times. With your method I had done it the first time. THANKS <3

that is not how bend tubes

I was.confuswd during the whole video. Still don't know how to measure a 2nd bend.

So that tube is 14mm? This is what I wanted to know, how do you measure existing tubing size, to know what replacement tubing you need... you know, in case you inherited or purchased a water cooled system that you didn't build.

Just curious as I haven't really seen it done, but could we add a loop in our bend? That would look cool.

Do you have any videos of you doing the bending and how you adjust for a missed bend? I’m using the same Corsair tubing and any time I try reheating and straightening to do the bend a little farther down it always goes to shit.

Am I the only one looking at this thinking it should've been a 45 then 90, does adding too many 90's slow the flow?

man, 90s... two even 3 sometimes no issue... 3rd one gets tricky with measuring... but a 90, with a reverse 90, into 135 degree is kicking my A right now... just burned through a whole pack of PETG. Any vids on 135/45s? I need to get a better tool or something these thermaltake tools are nice but i swear they dont always seat well in the 16mm channel

I wonder if the fluid pressure will decrease for over two bends

Great video. I wasted a lot of tubing on my very first build and this video will help a lot for my next build, which is in play now.

Screw a couple flat bend tools to a piece of plywood. Make markings on the wood. Voilà, it’s super easy.
