View Full Version : 1/2" Thermochill Barbs

I got these barbs today with my PA 120.3. On the baggies they came in from NCIX they say "Thermochill 1/2IN Chrom Plated Barb Fitting G3/8 Threads." They looked a little small, when compared to the 1/2" D Tek barbs I bought. The D Tek fit nice, and snug on the barbs, well the Thermochill ones are anything but snug. I bet this has been asked about a billion times, but did I get shipped 3/8" barbs rather then 1/2" barbs, or am I dumb?

You're not dumb, and those are what were shipped to us as 1/2" barbs. You're not the first person I've seen complain about the Thermochill barbs being too loose.....
I usually crank a few zip ties onto them or worm drive clamps to get a good seal, but imo they're more like 7/16" barbs...

Oh well that sucks. Why would Thermochill do this? They make good radiators, but it seems like they are just lazy.

I've never seen anything made by Thermochill that is not of the highest quality.
Honestly though I use plastic barbs on my T. Chill rads at home.... :(

Oh that sucks. I guess I will have to go hit up my local plumbing store for some real 1/2" G3/8 barbs.

Feel free to return those ones if you'd like. Email me at Linus@ncix.com and I'll see what I can do for you.

Or do like me and find a G3/8" to G1/4" adapter (like McMaster 4860K657) then get some good G1/4" barbs like the D-Tek high flow ones. With the adapter, it open up the horizon with the bigger selection of barbs and fittings.

I noticed the same thing about commercial 1/2" brass barbs. When measuring the OD they area actually about .475", not .5. Dtek barbs are even more oversized than most 1/2" barbs where the extremem barb OD is .570".
Anyhow, the smaller size is standard in terms of what commercial brass hosebarbs fittings go by. I think it's just water cooling where we demand a slightly oversized barb because of the "Leak" concerns we have..:D

Ya was wondering why these barbs I bought at Canadian Tire once were only 7/16". I thought being Canadian Tire they just could not measure anything.
EDIT: Anyone know any good sites that I could nab some larger barbs threaded for this rad, that also ship to Canada?

I thought they looked a bit small :P
Do you think they'll still seal ok with 7/16" tubing?

it would be nice if thermochill made there rads G1/4" threaded or if D Tek could make some nice Highflow barbs that fit the current thermochill 3/8" threads

Well I put in the rad tonight. Ya the barbs are too small for 1/2". I have 3 zip ties per barb. It doesn't leak unless a move the tubes. The plumbing store failed to have any G3/8" barbs, and I can't find a G3/8" die anywhere around. Maybe someone wants to make me a barb or two? :D

The larger G 3/8" is probably a fair part of the reason the Thermochill rads flow as well as they do. I noticed going to 5/8" barbs on my old MCR320s (Old version ran 3/8" NPT) gave me a better curve than swiftech's posted curve....
So the larger ID of the barbs probabably help some.
Anyhow, Petra's appears to be Out of Stock of theirs:

My lathe doesn't have threading capability, so I'd have to buy a 3/8" BSPP die before I could make any either, though there's probably a decent demand for a higher flow barb with all the PA's running around. McMaster-Carr sells both G1/4 and G3/8" dies, but they're $38 a piece...
Someone with access to a swiss screw machine ought to crank out a couple of hundred...they'd probably sell really well. Where's Iandh, he could do it...

Ouch 38 bucks is a little high for me. According to Linux AquaXtreme made my 1/2" barbs, and well they are not very 1/2". Maybe someone at Petra could confirm that they fit snuggly over 1/2" tubing?

Yeah I don't know. The link says those are 13.5mm at the widest point which is actually larger than these G1/4 barbs:
http://www.petrastechshop.com/dadenpesefig.html
. Measuring my 9/16"-18 High flow barbs are about 14.0mm, so that would be a little thinner.
My D-Tek barbs are 14.5mm at the widest point, which is oversized.
Not sure what sized barbs you have, but it seems like the oversized ones like D-Tek makes are preferable for 1/2" ID tubing.

or if D Tek could make some nice Highflow barbs that fit the current thermochill 3/8" threads
...we're still badgering them about that... hopefully something will come of it sometime soon :rolleyes:

You and me both.... Maybe someday Danny will get sick of listening to us gripe and make some sexy G3/8 barbs :)

where would one get the adapter that Xilikon was talking about? http://www.mcmaster.com/ PART # 4860K657 It goes into the rad, and then your barb screws into that.

Actually the Thermochill barbs were made by AquaXtreme, who (afaik) have basically gone under at this point, so I'm not sure who is producing them now....So what's the real story on AquaXtreme?
how about 5/8 barb for 1/2 tubing?

AquaXtreme's barbs were never particularly available in the UK... we've never got them from them. We TRIED to order a few thousand, but it never went thru. We also tried to go with D-Tek, but things weren't happening particularly quickly, so we now source them within the UK.

Should be available from most good plumbing / hydraulic components stores in Europe / UK.

Anyone know of a source for AquaXtreme High-Flow Fitting (G 3/8" Thread, 1/2" OD) threads? Petra's is still out and I can't find them anywhere else. Haven't found them in any local HW stores either. Not having them is holding up a major new build...:mad:

I just got the adapters in today from Mcmaster and they are very nice. They are chrome and have a rubber ring inside of a metal washer. I have a pair of EK barbs I plan on pairing with them and then chunking those cheap plastic ones that came with it from DD out.
Does anybody know how well the thermochill barbs will work with 7/16" id tubing and worm drive hose clamps? This should work well, correct?

The trouble is that AqX has pretty well folded as a company, due to things that I won't go into, and the result is that the barbs aren't available any more. A slightly longer, more involved explanation would include things like us [possibly] still being able to get the barbs if we were willing to charge $5+ per barb and wait for them to have them made... not taking into account that they screwed us on the last large batch, which caused us to sell them all at a loss because we were unwilling to pass the costs of their actions off on you guys.
Hopefully D-Tek will come through for us...
I would be (well, would have. already ordered the thermochill ones) willing to pay for the barbs. In the grand scheme of water cooling, it's not that much.

I really don't get what exactly is so objectionable about the DD plastic G-3/8 barbs. They work perfectly well for me.
Actually, if you don't mind brass, wouldn't this work? Need to add some o-rings though.

I'm not sure those will work isn't the PA120 series BSPP threading those fittings are NPTF.
NPTF (Dryseal) threads are compatible with NPT threads.* Rotates 360° for easy installation.¤ End has NPSM (National Pipe Straight Mechanical) threads, which are compatible with male NPT threads that have a beveled end.

Here's the adapters 3/8 to 1/4 bspp. I plan on using these then either T pipes fittings (if i put temp sensor on in and out of rad) or barbs.
