Restrictive bits power fittings

[astrodanco]

I've found that in my very simple CPU only loop one single Bits power "Q" fitting reduces my flow by 0.65 LPM more than does one single Koolance 5-way fitting. That's a lot of extra restriction for one single fitting.

The Bits power fitting is of course much sexier (understatement). For now I'm going with the extra flow over the extra sexiness.

BTW, the Koolance 5-way fittings do have a wider bore diameter inside once you get past the G-1/4 fitting bore. But they're also twice as long inside. Interesting to see the difference. I'm now going to order a Koolance four way which is more comparable to the Bits power "Q" length wise.

It doesn't show well in the above pictures, but the inside of the Koolance 5-way is considerably more roomy than the inside of the Bits power "Q". Why that should make any difference considering that the water has to go through the G-1/4 threads on each end which are the same size on both, I do not know. I put my drain line on the bottom and my temperature probe on the top. Maybe the extra room inside the 5-way gives the water more room to get around the probe tip.

.65LPM on a SINGLE Q fitting? Thats insane!

It doesn't surpirse me. Those Q fittings didn't seem to be designed with flow in mind. They are basically just a big mixing pot.

the q fitting is high flow...how did you get 0.67lpm drop?

Just noting my FM-17 (via TMS-200) flow meter reading. Sure, it's probably plus or minus some on accuracy and none too certain on precision. However, the only difference between before and after flow readings was switching out the 5-way for the Q and vice versa after I screamed bloody murder.

are these what you are talking about?

My perfect 90. :rofl:

2 way to the res, 1 straight down, and with a silver stopper on one end, and temp probe on the other.

that still goes through one barb...the bp 90 rotary should eat that big 90...

NaeKuh-

You could almost call that your turbo flow manifold..

"When one port just won't do...that's when you need turbo manifold!"

lol :D

it inlet at 1...

then outlets to 2 at a 90 to lessen restiction and also increase the flow though the res with the t-probe.

if i had a dual inlet, that would get messy, but my pump has a dual inlet.

No, please see revised OP. Thanks.

I wonder if the problem is the water flow going up into one of the blocked outlet ports, before finally heading out the correct outlet? Most plugs don't have much thread, so they won't actually occupy the entire outlet they're plugging. A good 90 will try to incorporate at least a small curve on the outside of the bend.
