Just so everybody is clear here (including myself.... :) ).

The barbs are 7/16 which would be OD, while the ID (inner diameter) of the hose is 1/2 (8/16).

Doesn't that mean that the tubing will be too large for those barbs and possibly leak?

That was why I was wondering if the heat would shrink the tubing - perhaps when it cooled. I have some danger den clamps and lots of zip ties (I read somewhere in my H20 search that a zip tie works well as a clamp) so I hope i should be good.

I don't know for sure but I think he was referring to since the swiftech tubing is actually 7/16 and all the barbs are 1/2 it is much easier to soften the tubing with hot water before trying to attach it. I had to do it with my swiftech setup and it makes it a lot easier

I think that's where the confusion is setting in.........

The tubing he's looking at is actually 1/2 ID, while the swiftech tubing is 7/16.

According to this..... http://www.ncix.com/products/index.p...cture=Swiftech the pump has 1/2 barbs so it should be a good match for the tubing he has picked.

lol... well whatever was or wasn't miscommunicated = during my research I've read that there is actually an advantage to using 7/16" tube with 1/2" barbs because while you might have to fight to get the tubing on initially it results in a much tighter seal for the long run - I'm actually thinking about using 7/16" tube for this reason :)

Ok. Let me all clear this mess up.

First the pump says 1/2" barbs, but they are 7/16" OD in reality. The edge of the fitting (where the boss is) is 1/2" OD.

The tubing that comes with the Ultra and Ultra+ kits is 7/16" ID, where resides the difficulty in installing that tubing on that pump.

7/16" OD barb and 7/16" ID tubing. That's why I wrote to heat the ends of the tubing (for expansion) prior to installing it - once cooled, it will shrink back to 7/16", thus making a very tight fit.

Now the Tygon is a true 1/2" ID tubing. With 7/16" OD barbs on the pump and 1/2" OD barbs everywhere else, it will be a breeze to install all that tubing - just make sure to properly secure the tubing using the clamps.

Now for that single reason, I strongly suggest to use 7/16" ID tubing - I only use that. It's a b*tch to install, but it's so tight that clamps are not necessary (but I still install them). But it is mandatory to heat up the ends (for expansion) for easier installation. Just be extra careful not to have any water drops on the components...

Cool! Thanks 3.0charlie.

I'll check out the 7/16" tube. As I posted above I've also read about the long term advantage of a tight seal at the price of a little more sweat for the inital setup.

7/16" OD tube on 1/2" ID barbs is tight. Very tight - but feasible. Heat the ends, and be ready to put some weight to properly make the connection. Once started, don't stop pushing until the tube reaches the end of the barb fitting. Then install the clamp.

And don't forget to check the barbs before installing the tubes - once the tube is installed, it's too late to torque the barb again if it leaks.

ORDER PLACED! :)

I changed a couple things:
I got Swiftech 7/16" tubing instead of the Tygon
I got a Black Ice Xtreme II instead of the Magicool Rad

OK... Why hasn't it shipped yet ?!?
:p
