That is EXACTLY the pack these problem connectors came from. There are the 4x 45 degree g1/4 anti twist packs and the 4x 45 degree with compression on the end. Both have leaked for me.

I used Thermochill's EC6 (clear) in the loop. If it has leaked on the graphics card then I have been using it with the liquid on there before without any (obvious) issues. Obviously I don't like liquid on my electronics anyway.

Did you manage to fix the leaky fittings somehow? I'm filling my loop later this evening and I'd like to use my TFC 45 degree adapters (compression fittings) in the build. So, I'll try to lube the o rings and maybe use some teflon tape? Would it be advisable to tape/epoxy them at the rotary junction if they start to leak?

I replaced the leaky TFC fittings with Bitspower ones. I still have some TFC ones in the loop (of both types of 45 degree) and I'm not replacing those, yet. I've found a lot of threads around the same timeperiod (sept 2010 until now) which has people reporting these rotaries are leaking. But, I'm willing to do an experiment to see if it is TFC using low grade materials or just unlucky on my part.

I also removed a lot of connectors/extenders which I was using for a 120 rad at the bottom. I removed the rad entirely in an effort to redesign the thermal path - I didn't pipe that directly before because of the angles.

I recommend you dunk the fittings (as recommended in this thread) in the liquid you'll be using to fill up your loop just to lube them a little bit. Unfortunatelty no amount of teflon tape would help here as it was NOT leaking on the screwthread. It is the oring inside the anti twist/rotary part which you cannot see which leaks. I guess you might be able to teflon around the outside of the rotary part so that it seals the leak inside the gap - but I'm unsure if this would work. I had a similar thought using duck tape (lol).

Either way I've remained under water and no damage appears to have been caused. That leak I suspected above the GPU doesnt seem to be there. I let this thing go through a full 2 day of leak check and air removal.

I hope my new BP 90's don't leak...only 2, but it would make me a sad panda.

I have a BP 90 with the compression end in my loop. I have another BP 45 with compression too. So far so good. I have somewhat more hope for BP to not leak based on a huge number of people using BP and recommending them for their quality. TFC however was mostly unknown for their fittings (only known for their radiators) when I used them. Now TFC have proven to be unreliable.

Well that's a bummer. Do you know if they can be disassembled so the rotary oring inside can be replaced?

I assume they can be disassembled, but whether this is easy and will not do any damage is not something I know.

You might be fine with the TFC 45s. I could just be very unlucky and have a crap batch with substandard materials.

Well, I filled my loop last night using all 4 of my angled fittings, and none of them have leaked so far. Some of them were really hard to turn at first, though.
