Koolance 1/2ID - 3/4OD compression which tubing?

post #1 of 7
Thread Starter 
Hi all,

Im about to order a whole bunch of koolance compressions like these:

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90

After reading this thread:

http://forums.overclockers.com.au/showthread.php?t=978555

Which states that the XSPC tubing came off quit easy with the koolance compressions granted these where the older silver fittings from koolance.

I already have Primochill Primoflex advanced LRT (1/2ID - 3/4OD) clear tubing...

So can anyone of you confirm whether the primochill tubing fits tightly on the koolance compressions i wanna order?
If not il go with bitspower compression....Since i got Bitspower 1/2ID - 3/4OD black matt i can confirm that the advanced LRT 1/2ID - 3/4OD tubing is a very tight fit i can not pull it out except maybe with extreme force. Which is a BIG plus!

It got me hesitating ordering these Koolance fittings even tho i like the looks very much....unless users can confirm its good from own experiences.

Thanks in advance.

Not many replies...

So i went ahead and ordered some of my components reservoir, cables and only ONE koolance 1/2ID - 3/4OD compression fitting i should receive them in 2 or 3 days. That way i can personally check if the Primoflex Advanced LRT 1/2ID - 3/4OD tubing is a good match with the koolance fitting.

Il report back with my findings for those who are interested as well, its a good thing i have also bitspower black 1/2ID - 3/4OD compression for a good comparison.

Yeh I didn't want to reply and take it off the unanswered list. I have had problems with certain tubing on certain fittings. Xspc has different lines of tubing and I can say that the 3/8 x 5/8 high end Xspc tubing works with bits power extremely well but won't come off monsoon even when you try. The compression ring gets stuck and you have to cut the tubing off then use channel locks and a huge screw driver to get the rest of it out which scratches up the fittings really bad.

So I can confirm some fittings don't work well with some tubing.

The soft Xspc tubing seems to be thicker than the cheaper harder Xspc tubing.

I have had no issues with primo chill 1/2 any of my fittings but again the company makes several different products so you can't be certain they are all the same.


It is a good thing you are double checking.

Thanks for the reply,

Yeah one needs to double check infact i did have 3/8ID - 5/8OD primoflex advanced + both Bitspower (black) and koolance (black) 3/8ID - 5/8OD compressions i can CONFIRM they both do well in regards of tightness its hard to pull out the tubing and its even almost impossible to pull it out from the Koolance compression which to me is a big plus. Back then i also ordered Tygon R6012 Norprene and....well it came of pretty easy on both the Bitspower and Koolance in comparison with advanced lrt tubing....its a difference between night and day so to speak....

I have no clue whether the 1/2ID - 3/4OD Advanced LRT will be a tight fit also on the Koolance compression hence i ordered one single Koolance compression. As stated before with a Bitspower 1/2ID - 3/4OD it really is a tight fit on the 1/2ID - 3/4OD advanced LRT tubing, so if the Koolance is not of my liking il switch to Bitspower and i will report here of my findings.

Update:

I finally received my Koolance 1/2ID - 3/4OD black compresion fitting.

First of all i also have Koolance 3/8ID - 5/8OD black compression AND Bitspower 3/8ID - 5/8OD black compression
As well as Primochill Advanced LRT 3/8ID - 5/8OD

Both the koolance and bitspower work very well with the primochill advanced tubing they both have a tight seal, putting the tubing on the koolance and bitspower barb was hard had to heat the tubing with hot water. It was very hard to pull out the tubing from the bitspower fitting and even harder or "impossible" from the koolance fitting. So they are in my book BOTH a good match with the primochill tubing. Its obvious no one EVER going to pull a tube from a fitting with the force i used lol but it does give me an idea how well it all seals...

I also tried Tygon R6012 Norprene 3/8ID - 5/8OD on both the bitspower and koolance and i could PULL OUT THE TUBING fairly EASY not much force was needed!

Next on to the 1/2ID - 3/4OD

I have:
Bitspower 1/2ID - 3/4OD black compression
Koolance 1/2ID - 3/4OD black compression
Primochill Advanced LRT 1/2ID - 3/4OD clear tubing.

With the bitspower putting the tubing on the barb was "with a bit of effort" next tightening the nut which was as expected not able to screw all the way down.
Next i tried pulling the tubing with force then even applied more force....nothing could not pull it out.
Next i unscrew the nut to see if the tubing did moved and it did....with extreme force i was able to move it 0.5mm - 1mm lol in other words the bitspower has great sealing and gripping.

The Koolance fitting:

Putting the tubing onto the bard was a bit more easy compared to the bitspower fitting...
Screwing the nut which i could do practically all the way down which i felt as more sealing ie i could feel the sealing better and better.
Next trying to pull the tubing with the same force as the bitspower i could not pull it out.
I unscrewed the nut to see if the tubing had moved its the same as the bitspower maybe 0.5mm - 1mm i tried a couple of times for both the koolance and bitspower some times both didnt moved the tubing one bit while the other attempt increasing pulling force did very slightly moved the tubing.

So according to my opinion they are BOTH very good in regards of sealing its obvious they both have their own "blueprint" but they work thats what matters.
It depends on ones taste.

I hope this help those who plan to buy Koolance 1/2ID - 3/4OD compression with Primochill Advanced LRT 1/2ID - 3/4OD tubing. ive tested it and its great.

The tygon pulling out is scary. Just goes to show you almost need to do what you did...

Even different batches could possibly be different.

Thanks for the report.

Thanks,

I wasnt the only one who confirmed the issue with Tygon norprene R6012 please note this was with 3/8ID - 5/8OD here is a link to a german forum (dont worry my post and all replies where in english)
A very helpfull guy made some tests with various 5/8OD fittings from different brands with the Norprene tubing have a look:

http://www.hardwareluxx.de/community/f137/any-one-tygon-norprene-compression-fittings-963610.html

He confirms it CAN BE pulled out rather EASY...
And by easy i mean a difference between night and day...that tells a lot.
Im not even going to try Norprene 1/2ID - 3/4OD which if im not mistaken has a thiner wall tube imo its best used with clamps.
