Let me refer u to http://www.xtremesystems.org/forums/...3&postcount=84

FYI,
I created this little set of comparison photos, but this time I used my smaller/brighter light tent for hopefully better pictures.

Koolance has come with some now Compression fittings. Dont know that the diffrens is form the old. Someone do?

[Utnorris]

I like my compression fittings from Koolance. If I had to say anything negative it would be the color, but that's not a biggie to me. I get plenty of flow from mine and they are 3/8" compressions.

looks like the plating is coming off, on another note ive noticed that my BP fittings oxides pretty quickly

Pics please...

will do

[NaeKuh]

I ran across this picture of some Koolance fittings, is this rust or galvanic corrosion ?????

WTF?

R3 i cut open one of those compressions with a lock cutter. Its brass though the core.

Since most likely your never gonna use it, Can you cut that up for me. If they did a swap on you, OMG im gona unleash hell.
Expecially since i was the one that recomended it.

EDIT: oh its not yours, and theres no way to tell if those are the ones koolance says that are brass. Guys MAKE SURE IT SAYS BRASS, otherwise OOPS on you.

I wouldn't call it abrupt myself, that are actually nice tapered transitions compared to some other fittings like 1/2" NPT plastic barbs that have a 90 degree sharp transition in ID sizes

It looks like a fairly nice 45-60 degree taper to me on both ends which is good...the chamfer on the threaded side is also going to help with restriction. Granted it is a 9.0mm ID, it's the transitions that are more important than the ID itself when it comes to restriction. The Koolance fitting has better transitions at the barb entry and threaded end (smaller wall to impact)

I plan to do some pressure drop testing to confirm, but I wouldn't at all be surprised if the smaller ID Koolance fittings have lower restriction overall because of the better tapered ends.

OMG NO MARTIN!

R3 running around going Koolance FTW! is something I DO NOT WANT TO SEE!

LOL! It's all moot when you start considering how small of a restriction we're talking about, but it's something to have fun with.

I've got a crap load of fittings sitting here waiting for some sort of review. I'm thinking a pressure drop and holding strength type of test is a MUST!!...

I've also got a bunch of quick disconnects and other goodies to test...

[Martinm210]

IMO, my RD30 will mow through any restriction due to not having a supposed "nicely tapered" end....

Then why are you worried about your "10.0mm straight through" preference?..

Just think of the .00001GPM you're just "GIVING" away...

[Boogerlad]

the feser one looks like a copy of the bitspower one.

[luxbel]

So do the DDs. You know there is something called OEM'ing?

[Boogerlad]

the dd ones are bought from bitspower. But the feser one... It looks like a bp but put in a cast, and then cloned. It doesn't look as sharp. I'm not saying feser stole the design, but it looks suspicious...

Careful now, that's a whole 'nother kettle of fish...

Feser steal their designs, Koolance aren't capable of making anything decent and if it is it's got to be alu, man people drop the fanboism :/

[NaeKuh]

excuse me..

I have a couple of things from koolance, which:

1. has better machining quality then EK. [I even got R3 convinced now, which is why he doesnt say a counter arguement besides EK is sexier]
2. can not be replaced even by bitspower in what they do
3. Isnt made of alu.

and yes you should drop the fanboism and give the good koolance products a chance.

Which is good? ASK US.

i read the description and it say it was made with nickle plated brass.so is it safe to use them?

if your reading that off koolance's website then yes.

They did a oops on the steel plugs, appologized publically on the forum, and offered an RMA to brass plugs free. You didnt even need to send in your old plugs.

They also said, for future references, write down brass plugs in notes, and they would work hard at making that request.

If it doesnt have plugs, then yes id say its safe. I have a few doubts on the quick connects as i think the spring inside is a form of SS. I dont think there are such things as brass springs are there?

i have 2 plug that came from new koolance DDC acrylic top, is it made from steel as well?,

Dean said the newer stuff was going to use brass, however, you should put a magnet next to it, and see if it attracts.

I like my Koolance compression fittings because they work and they a decent price. $9 a pair they are pretty close to regular barbs in price. That isn't fanboism, that is fact. Just because people recommend a product for an application does not make them fans, even some Thermochill people recommend Swiftech's as an alternative based on price. Doesn't make them Swiftech fans, they just recognize there are always more than one choice.

[Boyu]

i just noticed that my koolance 3/8 id comp fitting has steel part on the locking mechanism for the tubing, is it the same for 3/4 od?, i tested with magnet
is it ok to use?,coz i think this part will not make any contact with the coolant right?,

this is the part that made from steel

[NaeKuh]

ROFLMAO..

That isnt even wetted, so why does that matter?

The only time you need to worry about mixing metals is if your water is touching it. That is a clamp that goes outside of your compression barbs to clamp it. It never touches water, so you dont need to be worry about it.
