solid vs flexible tubing

[SolarNova]

Glass is better in almost every way when it comes to hard tubing. it looks better, is clearer, doesn't stain,works will all coolants, and doesn't scratch as easily.

 

its a tad harder to work with though being that u need to buy a couple extra tools to work with it, a proper cutter/scorer for the glass so u can cut/snap it, and a sander/grinder to smooth out the cuts and ideally you would also chamfer the ends.

 

That being said, hard tubing regardless of what type, is more prone to leaks than soft tubing simply due to the way the seals work, you rely solely on the fit of the tubing and the o-ring(s) of the fittings, compared with soft tubing where the tubing itself makes the seal and you can tighten down with compression fittings making them near impossible to remove.

 

Using fittings for bends is going to increase cost greatly.

 

An alternative is to use soft tubing and design it so your tubing runs are as straight as possible to give the illusion of hard tubing, its cheaper, somewhat easier, and less prone to leaks.

Incorrect, List of plastizier free tubing I have used.

1. Primochill LRT
2. Mayhems Ultra clear
3. Tygon e1000

Apparently alot more manufacturers are now producing tubing that doesn't contain plastizier, so sorry.... you're wrong.

 

"plasticisers" is a very large list of elastomer compounds. Primochill lists two of them that are not present in their product. Well that's great. Good for them. Do they want a cookie? They have to use SOMETHING to make it flexible.

Fittings have an o-ring on hardline that clamps against the tube and then fitting, the top of the fitting then compresses the o-ring making it impossible to leak unless the following has happened.

1. The oring is damaged
2. the tube is the incorrect size for the fitting
3. the tube doesnt sit in the bottom of the fitting correctly
4. the tube has been cut or bent in a way that exerts pressure to deform the oring

If you're taking this personally, I will ask you to stop now and leave the thread, you're not helping anyone. I've used those tubing listed and nothing has gunked up my blocks other than algae growth from not using a biocide. If your ego is getting in the way of helping the OP then I recommend leaving.

 

Things you have incorectly listed:

1. PETG is hard and brittle
2. All soft tubing has plastizier in it, I can actually confirm this is incorrect.

Do you have a plan on how to cut the glass to length?

i've watched some videos and the recommended way seems to be by scoring a point in the glass and then breaking it apart with your hands

Spoiler

 

I'm not arguing with you about the PETG and Acrylic difference. I mixed that up, i stated as such, and for you to keep bringing it up just to pound me down more while simultaneously telling me not to take it personally is incredibly infuriating. Not sure WHY you chose to do that, maybe you do it often and can't help it, but perhaps you can understand why anyone would become angered by it.

 

Secondly, anything plastic (which is a term used to describe a property, not a thing) contains a plasticizer (which describes a thing giving a plastic property). You can break that word down to its elements to understand it better: Plastic and -izer. If you still need some reference material, look up the words "plasticizer" and "plasticity" in the dictionary. You can also try using it with other words, such as energizer.

I donno if that was worth it or not. OP, good luck on the glass. It certainly is the best solution to use for long term aesthetic and maintenance reasons IMO. certainly not the easiest to work with, but the reward is worth the effort. One last bit of advice: chamfer the edges slightly so that you don't leave a cutting edge that may damage the O-Ring in the fitting when you press them together.

If you feel I'm attacking you, you;re wrong again, I'm just pointing out where you're going wrong. Teachers and such do this all the time, they're not personally attacking you, they're trying to teach you. This information will be read by many people over a substantial amount of time. 

If i mix something up and someone points it out then its fair game, I honestly don't mind, what i do mind is when someone gives someone incorrect data or information then argues the point when i've put time and effort into researching it, think scientists vs facebook medical experts for example. You told this user to go to a hardware store and buy generic off the shelf tubing with no idea what is in it or how it will affect his system, I said use proven products, I didn't personally attack you, i just gave better advice.

I'll leave it there as the thread is turning into one person being upset and the other just trying to spread good information, feel free to pm me if you want to continue.

chamfing seems to be really important since even ek has a warning on their site

I use some 90° bend glass tubes in my build and used this tool: https://www.amazon.de/Schneidewerkzeug-Schlaeuche-Rohrschneider-Schneiden-Durchmesser/dp/B01EHQ34IW/ref=sr_1_4?__mk_de_DE=ÅMÅŽÕÑ&keywords=glasrohrschneider&qid=1555438248&s=gateway&sr=8-4

and some diamond cutt off wheels for the dremel to cut them to size.

I did never regret using glass tubes.

Yes it works pretty well, but you don't have to use a drill, just turn the tubes a couple times by hand. For deburring or small length corrections are the diamond dremel wheels very useful
