1/2" to 3/8" ID without a reducer...

[Ko7Ad]

Good Day Cudders,

Earlier this year I got my new Mobo, ROG Maximus V, after a lighting strike during the holidays. But before that I had my watercooling setup just cooling my CPU with 1/2" ID piping. The Mobo as far as I have gathered has 3/8" ID barbs. The Problem!

3/8" ID piping will have a 1/2" OD that I could fit into my existing piping and could maybe add some silicone between them or something. The 3/8" ID pipe will thus only be needed to cover the barbs so I can get my 1/2" ID piping over it that way I can keep my 1/2" ID pipe look without reducers and crappy skinny pipes that does not match the rest of the install.

What are your thoughts or experiences?

Thanks!

this is a tough one

I would have said (and this in personal opinion), if you took a piece of 3/8 1/2 as long as the barb and place it over it, then put your 1/2 ID tubing over that, as long as you make sure that you put on a nice clamp and maybe an added cable tie (out of sight), it could just work

the thing to worry about could be that when you put on the clamp/tie, when you tighten them/it, that it may cause the tubing to start to 'fold' and cause an opening

would have said do a test run of the setup if you had an extra 3/8 OD barb

also if you do choose to go with some silicone, make sure it is proper stuff (used some silicone the other day to close tubing for use with water and the silicone came off) <- not WC related but still water related

As OFC said above if a 'fold' occurs it could lead to gradual erosion of the silicon which would eventually lead to failure - so not sure if it is worth the risk.
Do you not want to use a reducer at all or do you just not have access to one at this time?
I've seen piping with a gradual reduction (not in PC related use) which might serve your purpose.
Or depending on the piping you are using it might be possible to chemically weld the two together - the weld would not be eroded by water but I cannot comment on what it would do to the integrity of the piping when piping is put under pressure.

Thanks for the replies.

I guess the only way to really know if it would work is to test it for a day or two. I was just hoping someone had some experiance trying this. I am not fond of being a Guinea pig.

I know silicone does not bond very well to other materials and hence why it popped out on you, so I could take some sand paper to both pipes before adding the silicone. If I can get a rigid glue to stick both pipes or as Damin said chemical welding, then I could try go clamp/tie-less so as not to cause "folding". It may be high risk but maybe better than trying to get the clamp or tie to seal two pipes.

Now for the challenge of getting 20cm Red or Clear 1/2" OD piping...

The reason not wanting to use a reducer is that I want to route piping as follows Pump>Cpu>Mobo>Rad>Res, this will force rather tight bends from the Cpu to Mobo due to proximity, adding a reducer in the mix will make it more diffucilt to achieve the bends without a 45deg Compression fitting on the Cpu block (i think) plus will be unsightly.

note, my clamp/tie is not meant for when you just want to put the one pipe into the other...

it is for when you put both pipes over the barb...

if pipe A and B fit snug into each other, the chances for a fold could be minimal, but there is always the chance...

why I say, try and put a piece of pipe A into pipe B and have a test run of it like that (talking outside your loop with just the tubing)...

if you make pipe A a bit longer and let a piece of it hang loose, you can try and close it with finger and see if something comes out from where it is inside pipe B...

they were stupid to make that a solid piece of pipe, but see in the VI it is different

Good idea on the testing! I did not think of that. But the rest we were on the same boat, I may not have come across correctly.

It was stupid of ASUS, but its now a good way to get all the Cudders to upgrade...

Once I get hold of some pipe to test I will update you all with what happened

Thanks again!
