PETG Tubing VS Acrylic Tubing Pros + Cons - Page 33

post #321 of 380
I use the EK HDC fittings so EK compression fittings for hard tubing.. As everything in my system related to watercooling is from EK I also went with those fittings and have absolutely nothing to complain about...
post #322 of 380
this may be a stupid question but is there any easier way to cut petg or acrylic and getting a "cleaner" edge then with either a dremmal or hack-saw.....

reason why i ask was just searchin through the internet for a heated wire cutter.... would this work or would it be to hot??

It's not stupid question at all.

First of all for acrylic tubing there is no easy way, at least not at home. Laser cutter is nice... but hardly viable option. biggrin.gif

PETG is different animal entirely. Look no further than couple post above your question. There is no need for heated wire cutter. It may rupture PETG structure if too much heat is applied and tube will just look like burned inside.

Get composite tube cutter. You will get extremely clean cuts (except when you need to cut like 0.5 cm then it get dicey). My recent major refit took me less than a week to go through entire overhaul of tubing from classic ZMT to PETG and I was doing that first time in my life. With hack-saw it would be probably a month of work - tried it few test times, what a mess with no tangible gains. And then I had to accommodate sas expander into the loop. With flushing, bending, measuring, redoing 3 segments of the loop and stuff + filling the system back I was done inside one day and half of work. No sanding, hacking, white powder mess, splinters. Just measure, cut, bend, screw fitting, repeat. Plan is the most important.

Right now in my loop there is exactly 20 HDC 16/12 EK fittings (counted twice wink.gif ). I had only 1 oring causality at the beginning when I was trying to force the issue when fitting was dry. My beginner error.

Granted. When edges of the tube are sanded, tube slide in very easily, but IMHO to easily sometimes. I will take one or two damaged fittings and solid contact by tubing inside the fitting than no casualties, easy slide and potential leakage point any day of the week.

This is always a very interesting but opinionated topic.There are some interesting views here if one takes the time to research and read in the forum here,people are most helpful.

Is there any biting fittings for PETG? or is Copper my only option if I want a bite fitting (IE one that wont pull out easily) I am building a bench rig and want something for the lower loop that will not come out. The top will have passthroughs QDCs and soft tube, so no worries there just the bottom which will be permanent always filled loop.

like these? http://www.performance-pcs.com/xspc-g1-4-to-14-10mm-petg-triple-seal-fitting-chrome.html
I just put 10 of these in my loop last week and I think they're great. They hold on to the tubing very well when tightened down and they are not easy to pull out. It's possible, but probably a good 15lbs or more of force would be required. I could comfortably hang my coat on a tube suspended by one of these.

ONLY thing is I did have one g 1/4" o-ring blow out on me right when I tightened it down, I can't say it is their fault, but I feel like I should put it out there.

No, I want something like with spikes inside so it bites into the tube. I have a bunch of PC revolvers and do to someone saying they could I hooked a 420 rad from one and was able to carry it smile.gif.

My concern is more of movement and such, so the bench is aluminium and while it is pretty rigid it does bend a tad when picked up im sure, so the fittings will get moved around quite frequently, like flexed. I am worried that over time this will cause them to come out.

There will not however be any bends in the tubing, it will all be straight with bends taken care of by fittings.

I like the monsoons for my idea how ever I do not want silver in my loop so that's out.

hmm, I haven't seen anything with "spikes" that would dig into the tubing but I feel like this would be a bad thing for hard tubing like petg. Can you link to the ones you would use for copper? I feel like I could attach tubing to a large rad with my fittings and carry it around all day long too, only difference is mine wont mutilate the tubing once you pull it out one time like spikes digging into the tubing would cause. Perhaps I got confused somewhere worriedsmiley.gif
