Hardline Tubing Guide: Bending PETG and Acrylic | bit-tech Modding 

Thank you!

After many years of PC building im doing the same.... good luck!

I saw him use 350°C in another video. It seems reasonable, as I previously experimentally determined that 375°C worked alright for me.

@@Thorarin because those tubes are have different size, I don't know your Experimention isn't that size, which depends if the tube is smaller and goes lesser temperature then.

that's as the same as 130°Celsius, right?

@@a17waysJackinn No, acrylic takes up in the range of 280C. As he said it has a far higher melting point.

@@brettbainbridge3154 2:34 haha. 280° is great I think. but also as he said.. and maybe 280° is a good start to heating for acrylic.

Acrylic lasts longer as it's almost glass compared to PETG being plastic. Yellowing might depend on the coolant used but if you ran a clear one, over time I'd expect the acrylic to yellow a lot later than PETG. Firm lifespan or timescales I'm not 100% but I'd say PETG might last two years perhaps if anyone else can confirm? But in principle the effort you put into acrylic pays off in clarity and life span

Sounds like a you problem ;)

THANK YOU!

Distracting? more like Captivating

I agree... lose the stache...

​@@bittech1Real smooth real icy .

Yess, when using good sandpaper on hard materials like stone, metal, acrylic, etc, it's good to use water. Not sure exactly why, maybe for heat reduction.

​@@accumulator4825It's for some lubrication but main thing is it reduces dust

That’s an Alphacool Eiskoffer, for cutting the acrylic a coping saw does very well, as does a Dremel or jigsaw. You will want to sand the ends regardless though. I use a scroll saw and a belt sander + reamer for mine, but that’s because I have those tools already and they work particularly well

I think he uses the same temperature

You want to set it at a lower temp, better to take a little longer to heat up than it being way to hot and cause it to bubble.

Honestly the best way is to work in flexibility into your tubing routing. Tubes with multiple bends in them are very tricky to do reliably. If you can come up with routes that result in a run only have maximum 1-2 bends in them, and then instead rely on parts of the tube that you can trim to size, you'll have a much better time. There are systems like the Alphacool Eiskoffer that allow you to measure things out precisely, but in all honesty I've found them very hard to use compared with changing the route itself. Aside from that, lots of practice.

heat it up evenly and you gonna feel it, cuz it will become wobbly

Naa you can use any temp that’s hotter than that, just need to keep a closer eye on things.

look up watercooling "mandrels"

If you’re heating so high that dabbing some water on it causes problems then you’re going too hard to begin with. This isn’t glass, you’ll be fine. The advantage in cooling it quicker is that it prevents your bends from warping whilst you’re holding it in place.

@@bittech1 and the disadvantage is you can cause micro cracks which can under pressure become major cracks and leak, i know personally after spending thousands of Dollars on a system that i will NOT put water on hot tubes no matter the temps, just a risk i refuse to take

Just remember I’ve built a large number of systems ranging up to £25k+ and never once had an issue. I was one of the early adopters of acrylic tubing back before you could buy proper fittings for it even.

@@bittech1 so you would be willing to pay for broken components if one of your viewers takes your advice and cools it with water for someone building their 1st loop?

What a ridiculous statement to make. I suggest you just take a break, you’re obviously proud of building your first loop but there’s no reason to try and bring others down.

Small corrections, but nothing large

I’ve been using this method since 2013 and across many, many rigs, I can confirm that it does not cause stress fractures in the tubes.

дурачок тут только ты, потому что он умышленно это сделал дабы показать что акрил хрупкий в отличие от petg. Что вы такие дурачки то, что не можете даже в базовые знания английского.

I just noticed you did not say a temperature for the Acrylic heating, hope to hear that if possible.

Naah, I think it's fine if you just rinse it.
