Pipe bending 101 - Page 92

post #911 of 2160
I've noticed no flow or performance degradation switching to these fittings, so I see no need to remove the hex area so far. It's been around five days so far with no leaking, so the fittings are definitely water cooling safe.

Whether or not it's worth it is up to you of course. Bottom one is stock fitting. picture (Click to show)

I'm confused. Why does it have the hex on the inside? Does the outside not tighten it to block or whatever?

Yeah, that's just the way some industrial type fittings are made.

Hey im trying to figure out which tubing to get, and was wonder if the aquatuning black nickel fittings will work with acrylic tubing? I tried to see if someone posted that these will work, but i couldn't find anything. My first wc loop just want to do it right.

They will work just fine with acrylic.

Awesome read, thanks. thumb.gif took me a while but I finally read all the posts. I've been planning on a copper loop and now I'm thinking about going acrylic. Either way this thread is great. Lots of useful info.

I beleive if you use a fitting like this one, with an interior hex, you can tighten it using a hex key and then pop in your tube. Then you'll have a super clean look or if your in a tight spot and can't get a wrench in there. My 2 cent, wait make that a nickle, we just got rid of our pennies! This is SMC btw, i just googled it. The trick is finding the right size with the right colour.

But today McMaster just replied to my order saying they will not ship to Canada.

I have no problems ordering from McMaster-Carr and I live outside of Ottawa, Canada. Then again I order for the company I work for so maybe because it's a business.

I am in no way affiliated with this company but I can vouch that they do good work. If you are in the Midwest and looking for a place that will chrome plate your copper tubing.. hit these guys up.

I can understand for a fitting like that one. But that other one, you can tighten from the outside. confused.gif

I think you're getting the function confused. "Tightening" is referring to screwing the fitting into the block. The pipe/tube is literally just pushed in.

I'm sure someone will correct if I'm wrong. But that's my understanding of it. Also, I'm pretty sure tightening it down isn't that big of a concern. Finger tight is all you really need on a PC loop. Like a regular compression fitting.

Maybe they're just giving one the option to tighten from the inside or outside. Not sure of the logic. But then again if your in a tight spot inside would help. I can see it restricting the flow a little because of it though. I would prefer a fitting with the largest inside diameter as possible.
