enjoy :D
I love my CPC 1/2'' quick disconnects. have you got any of those laying around to test?
sadly nope...wish i had some...to test..and if they're really good.i'll keep em:up:
I'm going to be solely using these as a drain-fillport.
Glad I kept those out of my loop. Was planning on using them at first but once I looked at it closely I put them in a box and kept them there. Could be useful as drain and fill ports but too much of a flow killer for anything else.
Please excuse my ignorance but... What's the unit of measure?
GPM on the left, l/min on the right.
Nice quick test there :) Mirrors my findings too, which makes me feel good :p:
Should be GPM.
I have the Koolance VL3, the CPC for 3/8" ID (APC series?) and the 1/2" CPC NS6 series lying here. The Koolance are noticeably better than the 3/8" CPCs, but the 1/2" CPCs have a completely different construction, and I haven't tested those yet.
I'm gonna publish results flow for all of them once I get my proper rotameter, I currently have a Digmesa FHKUC but I noticed that the absolute value is not correct, and I'm not sure whether the relative values are correct either.
gooood to know:up:...it works ok with two pumps;)Quote:

Let's see how's first, you or Nickel020. :D
Thanks :)Quote:

0.25 GPM per pair it's a hell of a drop though... blimey!
i don't drive fast nor race, i cruise:DQuote:

So do I, and I won't be rushed :p:Quote:

I don't trust the FHKUC fully though, I did some manual testing with a stopwatch and I found that while it showed a flowrate of about 178l/h I actually was getting more than 200 l/h (different pump and loop setup for this test). That's why I ordered a rotameter (swiss made :) ) and when I get that and find some time I'll do a 1/2" tubing comparison with thebig NS6 CPCs.
Those are the 3/8" ID right?
Yes, they're a little more restrictive than 3/8" tubing though of course due to the shutoff mechanism.
Also, nothing beats the CPC NS6 1/2" shutoff mechanism, no water coming out at all when you open them :)
I have a ton and you could borrow whatever you needed for testing.Quote:

I have 6 unused right here.
Also keep in mind... if you'rel ooking for ultimate flowrate then these are the "mid-range"
Here's a list of all our shut-off valves and their flow-through ID
Dean i really wish you guys would make the VL4 with G1/4 threads so i can retire my VL3's.
QFT :up:. I think I remember hearing that they were being made, but I guess you would know better than I do.Quote:

I vote for G1/4 female-threaded QDs (VL4) as well. :cool:
VL4s in 3/8 ID 5/8 OD would be nice as well ;)
