how do T-Fittings work?

post #1 of 8
Thread Starter 
Wouldnt a T-fitting drastically degrade your loop flow by splitting it in two, as well creating two different flows? how do people use these?
post #2 of 8
I wouldn't use them to separate the flow to separate blocks... I have one in my rig but in mine the split leads to a drain port.

Most people will use T-Fittings in conjunction with a valve as a drain port. Others will use them as an extra port for things like temperature probes and silver bullets.

You are correct, T-Fittings will dramatically reduce the pressure of your loop if used to split water cooling loops.

Does it work like this? redface.gif

Sorry for my awesome paint skills, but I think you get the idea xD

MS Paint Pro!

It doesn't work like that. Where the T-Line splits you suddenly have 1.5GPM of flow when you started with 1GPM of flow. Before and after the T-Line you will have the same flow rate, it just depends what restrictions you have on each side. For instance if you have a GPU block on the left side of that picture, the right side of the T-Line split will have greater flow rate than the left side, but you should end up with 1GPM at the end.

I think you may be confusing pressure with flow rate. With a line split (like the one you just drew) pressure in the entire system will drop.

Alright, well im not planning on doing it, just wondering rolleyes.gif

wow +1 rep for all the answers! even the paint pro guy lol

okay so yea splitting your loop with them is bad, and I would even go as far to say that using it as a drain port doesnt it congest the flow? all be it not by much but still not that efficient. I was looking for some way to use one but definitely staying away now!

No a T-Fitting won't make a noticeable difference in loop performance if it's being used as a drain port. 

 

If I were you, I'd use fill and drain ports. In my years of watercooling, the things I've found most helpful are fill and drain ports. If you set them up in your loop you'll be glad you did when you go to drain it! Unfortunately I don't have the guts to cut into a $500 case, so I don't run them currently.
