Y-fitting instead of T-fitting?

[grandpatzer]

For my second watercooling PC I want to not have a reservoir.

I know the common thing is use T-fitting but aquatuning does not have T connector for my 11.1mm ID tubing, they actually have PVC 10mm that should work with hose clamps or zip ties but I'm worried risk of leaks.

I did find metal Brass Nickel Y-fitting 13mm so once warming the tube it will fit nice and with zip tie will be really well sealed.

Question: Is there any reason to not use a Y fitting 13mm Brass isntead of a T-fitting which I don't find?

I am in the US so I deal in inches instead of cm and mm, but from what I have seen 11.1 is 7/16" tubing if I am correct. Taking that into consideration, I would go with something like...

7/16" hosing fits nice and tight on 1/2" fittings without the need of clamps. Just use boiling hot water to heat up the end of the hose if you can't get it on. Hope that helps.

the answer is:

a T-fitting is for splitting one source into two flows

a Y-fitting is for merging two sources into one flow

Yes the ID of tubing is 7/16", I was not entirely sure about that Primochill 1/2" fitting because is also is made of PVC?

So can I use the Y-fitting for replacing res?

I already made order for the Y-fitting 13mm and T-fitting 10mm hopefuly one of them works

The 10mm fitting says 10mm tubing without additional fixation and 11mm tubing with additional fixation.

remember: by splitting a flow's source, the pressure/flow-rate decreases (and vice-versa)

I used 7/16 tubing with a 1/2" pvc reducer on a build, when I was taking the bits out to change the loop, the hose held so well on the fitting it was easier to cut the hose to get it off than trying to pull it off. And didn't leak/split in the system for a year before they wanted new bits installed. So yes it works well with them.

Then I wish I would have ordered the 1/2" instead then hehe.

I think I will choose the 13mm(1/2") Brass Y-fitting I don't think there is big difference vs T-fitting.

I also ordered the T-fitting 10mm but I'm worried install that because my tubing is 11.1mm, although the link states 11mm ID is good with additional fixation:

Edit--> So I have ordered T-fitting 10mm and Y-fitting 13mm, looks like I'm going for the 13mm Y-fitting to make less leakage risks.

He isnt aiming to split the flow just to use the 2nd line in place of a RES so if it needs some more fluid it just draws a little more in from that line,

@OP just make sure the line your using as the res is the higher of the 2 and any air bubbles should get passed into that one rather than going into what ever you have before your pump.

I think I will have one of the "arms" to radiator, the other will be the filling tube that is sealed when system is bled.

the "1leg" will go to pump.

Orange is rad, red is pump, green is tubing and the brown dot is where it is sealed with fillport plug on tube.

I'm no expert so don't take my word for it but, I'm thinking you should get a splitter that has an off switch or cut flow to one side because wouldn't the pump be sucking all the water out of the fill port tube as you continually fill your loop to get a flow but then there is no consistent flow going for the fill port so the pump would suck it dry and then squeeze the tubing flat since it is empty. I'm not sure how this works really since I've never liquid cooled but by my logic you would need a Y at the fill port area one connected to the out in the cpu so to complete your diagram starting from the fill port in top it would be...

In fillport - pump - out pump to rad in - out rad - cpu in - cpu outlet - Y on fill port

Basically you wouldn't need a Y on the pump at all with this system if you can follow it, try to draw it with your finger if you're confused also in my head this is a much cleaner loop than anything you could've had going with the current setup but didn't provide a complete diagram. And I'm assuming you're not doing a VGA in this loop either

That makes no sense... once the loop is filled fully how would it pull the spare liquid out of the fill port tube as there wouldnt be any space in the loop left to fill with water...

@OP have you thought about a res top for the pump? they take up little space and can look pretty nice.

I already made my order and read in past that those integrated reservoirs are a bit noisy

Ah fair enough, GL with your loop anyways.
