G1/4 1/2 Barbs Question?

[scaramonga]

A bit of advice required again peeps

In process of my i7 build and have a little problem with barb fittings.

Using 7/16 tubing on G1/4 1/2 tails.

I ordered these EK barbs and they fit, but do not seal as O Ring does not compress when tightened down on the following components:

XSPC Full Cover Razor GTX280 - Acetal

Swiftech MCR320-QP

Would these be better or even these?

Any help appreciated

I have just had a quick check of the barbs we have in stock and the length of the thread on all of them is pretty much the same.

you could try these as they are whats the XSPC block is designed to be used with.

Umm... RTFM????

If you are using G1/4” barbs/fittings with a long
thread you will need to use the supplied rings to
avoid blocking the flow.

That is not the problem, the threads on the EK barbs are fine, as in short, so no spacer is needed.

The O Rings seem to sit too deep into the thread housing, thus when tightened, there is no seal, the head just sits flat on the RAD & GPU block.

For the swiftech rad I think you can use something like this: http://www.performance-pcs.com/catal...ducts_id=23836

I think some people were able to fit the DD/Bitspower fatboys or Dtek fittings and it sealed just fine, but I'm not entirely sure.

That's strange. I'm looking at my (unused) EK fittings and EK stubs right now, both have the oring protruding ~1mm beyond the recess grove.

The EK fittings should fit you radiator as well. I have EK everywhere in my rig besides the FuZion block.

Thx buddy, but the RAD is the new G1/4 type already. Maybe these EK fittings are duds? I ordered 4 at same time and 2 fitted to my Delta 3 block OK. The O Rings do look kinda thin though?

This is holding up my build lol

These do RAD also? how quick can u get them to me

Post some pictures of your EK fittings so that I can compare with the ones I have.

[scaramonga]

OK, sorry for crap quality, but only got my phone camera and wanted to get close, but you can just see O Ring is flush with barb head, it actually sits inside and does not protrude much at all?

[Utnorris]

If you want, go to the local hardware store and get some new ones, thats what I did.

[Zehnsucht]

There is something wrong somewhere, he bought high-end fittings. He shouldn't need to go to a random hardware store.

Here's what they look at EK's site:


I'll take some photos at work today.

(Remember I use these fittings on my radiator).

A "useful" pic of the fittings on the rad and/or on the XSPC would be much more helpful.

Here are some high-res pics of my EK and EK Stub:

You sure you've tightened them properly on the radiator? I had to tighten them quite hard on my MCR.

Thx for the pics

I can see your fittings are exactly like mine, except your O Ring sits up from the head quite clearly. Tightening down on mine results in it can go no further, as in the metal is touching the metal, you can feel that there is no compression whatsoever. (Exactly what you get when there is no O Ring fitted)

I'm gonna order another variety today, many thanks for all your help.

Yeah, I have several different styles of EK barbs. The lips on them used to be more pronounced, and the o-ring was not recessed. Now they are recessed, which I think is the true G1/4 standard. This works good on blocks and rads that are flat around where you screw in the barb as it prevents the o-ring from slipping and possibly causing a leak. On swiftech stuff, there is always a recess for their barbs. As far as I know, their rads are still NPSM.

I'm sure you could get new ones if you complain from where you ordered them from. We have an EK representative on this forum, he might also be interested in why your particular fittings don't work.

I am using the Bitspower fittings with my MCR rads with no adapters, and they work just fine. I really like these fittings since they have the slot to keep the o-rings from stretching when tightened.

Got them from Watercooling.co.uk, and have just requested an RMA for sending them back
