Default Barb and Tubing Question!

Quick question. Sounds nooby, but meh better be safe then sorry.

I know people use 7/6"ID tubing with 1/2"OD barbs, but is it possible to do 3/8"ID tubing and 1/2"OD barbs?

I think you can if you heat up the end of the tubing in hot water before you put it on the barb. I don't think it would be that great though

I..... probably wouldn't do it. Are you just trying to avoid using clamps or ??

I really doubt it, and if it did work once the tubing settles on the barb it'll be stretched out really bad. It was hard enough getting 3/8id 5/8od tubing on a 3/8id 5/8od compression fitting.. unless you have a smaller od for your tubing, the wall wouldn't be as thick and it'll be easier to stretch and get on the barb but once again the tubing will still be stretched out pretty bad.

Well, I MIGHT do a watercooled pc one day. (I sorta know how.. Doesn't seem difficult to do. I've set up a pumping system and etc, for my aquarium)

I'm just trying to figure out what parts are good. It seems people try to stray away from Watercooling Kits?

Barbs and tubing just had me confused!

So, it's a better idea to do 7/16”ID tubing with 1/2”OD barbs?
Does it give a snug fit and etc? I'm not gonna cheap out on any of these tubes. I might go compression..

Personally I'd do 3/8" ID 5/8" OD tubing with compression fittings.

Watercooling kits like the swiftech and ek kits are perfectly fine but the rasa kit may limit you when it comes to expanding your loop. The bayres pump that is included with it is pretty weak compared to a mcp355 + top so you might run into trouble when you add more blocks if you want adequate flow.

The Swiftech H20 kits come with enough raddage and an mcp35x pump so you don't need to worry much about flow or cooling capacity unless you add an insane amount of gpus, ram blocks, mobo blocks etc haha. Same goes with the EK kits since the pump included with it should be on par with an mcp355.

For fittings you should decide on your decision between barbs or compressions. You wouldn't want to buy barbs and regret not getting all those shiny sleek looking compression fittings down the road If you go with 7/16id tubing on 1/2 barbs you still want to get some form of clamps as the tubing will still have a chance to slide off down the road no matter how tight it seems to be.

+1 to the 3/8 5/8 compressions though, that tubing size has insane bend radius.

the answer is yes! you need boiling hot water to heat up the tubing connection side. The great thing about using this size of tubing on a 1/2 barb is that the connection ends up being really secure.
the downside, difficulty in installation and because its so secure, removing it requires cutting the tube.

Or you could say that they may be less secure since the tubing has been stretched so tight it may want to pop off.

I never saw the point of streching tubing over larger barbs personally.
