Rotary Fitting leaking!! Suggestions needed.

[Fatfool]

So yes, A rotary has started leaking. Didn't notice till I opened the case to take a look and found the liquid level really low. I panicked and wiped off the dry dye surrounding the leak so it doesn't seem as bad as it was. Thankfully, it's leaking on the outer side of the fitting instead of the side facing the card.









Those are Feser 9017s aka 8mm ID, 11m OD 90 degree rotaries (1/4" Thread Rotary Right Angle Compression Fitting for 8mm ID - 11mm OD Tubing 4 Pack : Feser)
http://www.feser-one.com/site/produc...roducts_id=320



Apparently, it's leaking from both the G1/4 thread area and the rotary portion. Ironically, this is a fitting I would least expect to leak as it's in a rather 'slack' part of the loop.


(yes, I use multiple tubing types with Feser one black. Not recommended but no coagulation though )




Solutions solutions. I definitely cannot use a straight 1/4" barb there.
There simply isn't enough space.


So, do I get another pack of Feser 9017s? (aftr all, the 7 out of 8 fittings still work fine.)

or do I get another 90 degree rotary? The enzotech ones?

It's not a compression though. but it looks less likely to develop the same problem?

Also, I can't get any of these here so I'll need to ship it from the US or UK again. Will need to get more 1/4" tubing as well at the same time. Tygon B-44-4X sounds good? Soft enough unlike the damned silver tubing?

Thanks

(P.S I'm running an OCed QX6700 and OCed 5870 on a single 120mm feser rad!!!!)












Just joking. Its actually 2 X 120mm. the other is outside

From what i've heard from others, rotaries might leak when they get skewed by force with eg improperly bended tubing/or some component weighting on tubing attached to that rotary. No skewing/bending of rotary = usually no leaks.

[SoulsCollective]

Given the way the tubing is routed there you'd be much better off with a 45-deg elbow fitting rather than a 90-deg elbow. I've also had several bad experiences with leaking compressions from manufacturers other than Bitspower - BP rotaries are the only ones I'll use now, and I've not had a problem yet in about six loop builds for client PCs. They are expensive, yes, but for peace of mind I'm prepared to pay extra.

yes. That is indeed true. but in this case, it's pretty slack and yet has leaked. I presume that once it leaks, it's a goner?

and 45 degrees might work. though with the fan directly over the fittings, it could be real tight. but I haven't seen any 45 degree 1/4" rotaries around.

as for bitspower, hasn't there been cases where it's leaked as well? (complaints about loosening of the rotary and then leaks)

Warranties aren't gonna work here as they'll be shipped overseas. besides, I must say that 12 USD is REALLY high for a simple fitting that's made in china. Those fesers cost bout 11 pounds a pack of 4. I'm not sure how much a meal at macdonald's or subway costs in the US but I'm pretty sure it costs less than a single feser rotary. The high price may simply be... a lack of competition?

Personally, I've never had problems with compressions. Even those low end innovatek ones which were more of 10/8mm instead of 11/8mm worked pretty well. More of rotaries being the problem. caught a couple of them leaking at the start but they were fixed with proper placement of tubing.

yep. caught a couple of them when I started my loop. but I fixed them with proper placement of tubing. but that particular one was fine till now. (it looks pretty slack isn't it?)

Thats not a rotary. Thats a 90 deg compression fitting. Rotaries have an extra twist spot in the middle. Anyhoo, look at the BP rotaries or just the BP filttings like the one you have.

[Vinas]

I've had BP fittings leak personally when there was tension on the line. That said, they are pretty solid when there isn't a lot of force on them. Currently I'm using enzo 45 rotaries and they are rock solid also... On your gpu block can you switch the plug to the other side and use regular compressions.

it says rotary on the page. unless I made such a serious mistake as to buy a 90 degree fitting that wasn't a rotary, Install it in my loop and proceeded to twist it like a rotary thus causing the metal to break and the coolant to seep out.
I've seen the BP ones. The price puts me off. Could get like 3 meals at macdonalds here for the price of one

ah. Well, i didn't put much force on mine too and it still seeped out. what a bummer.

45 degree enzos? Too bad they don't have 1/4" love. But i'd be willing to try the 90 degree enzos even though they're not compressions and they look silly. build quality looks decent. Do they wobble around when pushed? How's it secured? I mostly have experience with compressions only. DO you cable tie them?

as for switching it over, that's a no go. The fan sits directly above both fittings. tried the straight compression barb. No go. not even with 1/4" tubing. Seen any 45 degree 1/4" rotaries around?


btw, I must note that the most secure rotary in my loop happens to be my 1/2" ID, 3/4" OD one.

Bizarrely, It's an el cheapo no name, roughly finished, industrial looking one that does the job surprisingly well. That rotary is under a hella lot of stress yet doesn't budge at all. oh my..... they don't have the 1/4" version though darn... I'd get a handful of them.

[astrodanco]

Use Bitspower rotary compressions.

Such as this double rotary:



Or this triple rotary:



But in your tubing size.

I know, I know, you'd rather eat at McDonalds...

[H20Cooled]

I stick with teh BP's and have had zero issues with mine when no force is applied to them. I have only had one BP rotary leak and that was caused by me being a fool when messing around with a HD and snagging the line.

[Waterlogged]

It's funny how everyone recommends BP rotaries even though they were the first to start leaking and we still see topics about them leaking pop up from time to time. The only rotary fittings I don't recall seeing a "help, my rotaries are leaking" topic about are Koolance. I could be wrong on that but honestly, I really don't recall seeing any "leaking" topics about them. If I'm wrong, please link me.

[Aphellyon]

Yea, I remember seeing a bp rotary leak thread around here a few weeks ago. Anyways, I ordered a hand full of bp rotaries from ppcs a little while back for my upcoming build. If I have any leaky ones, would it be better to deal with ppcs or directly with bp to get replacement/s?

Sorry if this is a bit OT.

because if you make things shiny enough.. people are willing to forgive and forget.

[astrodanco]

I have seen pictures of horrible corrosion with Koolance fittings and also someone complaining about them possibly being steel instead of brass underneath. Strange stuff.

koolance fittings dont have threads becuase no one buys them

From how long ago? I know in my case, it was left over stock that was not returned to Koolance from P-PCs and Koolance was more than quick enough to swap out at no charge to me. I have no problem ordering any of Koolance's fittings without any reservations at all.

Just goes to show that the majority of water coolers are nothing more than a bunch of Lemmings when it comes to fittings.

hah everyone is lemmings with everything... look how many ipad sell..

I was also afraid about my 45ºC rotaries (TFC ones...) but fortunately for me, they don't leak. I think that you should try to buy new ones, you may get better luck...because Bitspower in Europe is ridiculously expensive.


PS: how the heck do you have all of that with only a 120mm rad?????????

You see 2 tubes goes out on back... prob rad back mounted

My apologies, I should have mentioned that I've only used the enzo compressions and 45 rotaries. Both have been top notch, I'd put them up against my BP's which is a pleasant surprise! I've pulled very hard on the enzo 45 to see if I could make it leak. No leaks so I'd recommend them to anyone -- if you can find enzos in the size you need. TO be completely honest, the BP style compressions have a better finish IMHO. You would have to be very picky (and I am) to notice. I've asked several people that have seen my rig and no one can tell the difference (but me).

I think this is because the BP's are silver plated whereas the enzo's are nickel? For the price difference, enzo are the best price performance ration I've used.

That 90 you showed looks like a koolance... Does it have a red o ring?

[rootz0r]

Have you tried contacting Feser? Maybe they can give you a replacement.

It's not a rotary. A rotary lets you swivle it AFTER you tighten the oring down. The BP's ones in the pic here have a seperate ring that allows it to rotate. The Feser doen't besides it a pure 90 degree, and the inside is much more restrictive than the BP ones.

Feser says rotary, but it's not in my book. Typical Feser.

Where it's leaking looks more like a hose size problem.

[lennox]

Thankfully, it's leaking on the outer side of the fitting instead of the side facing the card.

After you locate the problem with the leak, be sure to take that block off your video card and check for water just to be safe.

They are indeed rotaries, and that is why they leak, as when pressure is applied they lose balance and the o-ring (the one that allows to rotate it) stops working properly and there you go: a leak.
