Hi all

Been using some rotary fittings on my Heatkiller CPU Block for a while now and keep having persistent bad luck with them - they leak if pressure is put on them in the wrong way, which makes any pc maintenance a very risky/lengthy job as i need to leak test if i move them at all.

Yeah, i know that this is a problem most rotary fittings have but these leak ALOT. They're just cheap things. If i had known rotary fittings were this unreliable i'd have never bought these.

Anyway, so instead of buying more of these dodgey fittings again, i figured i'd get something more reputable. Bitspower is a bit too expensive for my liking (plus, i'm skint) but fortunately i found these:

Are these EK PSC fittings reliable?

Thanks all.

What brand are your rotaries that leak?
There is an oring inside so they should not!

They're unbranded. It's these specifically:

http://specialtech.co.uk/spshop/customer/14-Thread-45-Degree-Rotary-Adapter-with-14-Inner-Thread--Black-pid-11566.html

They don't always leak, but they can (And do) leak if i say, unmount the cpu block or rotate them. They leak from the rotary joint itself, and yeah, it's definitely enough to cause damage. any mild uneven pressure from the hose will cause a few drops to appear.

I bought two more to replace them, they too had the same issue. I assume they're just not manufactured well at all.

Then oring is out of place and does not seal.

Yeah, i think the internal o-ring isn't very thick as there's also alot of "play" on the fittings themselves. they also turn surprisingly easily which has never been reassuring.

They're just crap, really.

Here's a picture of them in my system:

They're cheap, but not the cheapest out there, those EK fittings are only £1 extra.

(found the products official page:
http://www.ekwaterblocks.com/shop/accessories/fittings/adaptor-fittings/ek-psc-adapter-45-g1-4-nickel.html)

Anyone have any experience with these? I'm very tempted to give them a shot but again, as money is tight i really don't wanna waste my cash.

I have them. My first whole set of compressions. I did use barbs previously, but then bought BP's for a new build---- which are painted with black marker and leave stains all over fingers. So I ditched them and got ek for half a price and so far so good. Mainly these fittings are all made on same principle.

here's a tip for rotary fitting, they will leak if you put any kind of tension on them, since they aren't made to take any weight tube length is a big issue when using rotary fittings
even hydraulic rotaty fittings will leak if you use them other than how they are designed to be used. . .

just a heads up, since you might not even need new fitting just a different length tube to that fitting

The TFC ones are the only ones I've used that don't leak with sideways pressure on them. The 45ºC rotary 3/8" compressions they used to make leaked like a sieve but for some reason the seals in these work extremely well.
