EK blocks gasket rings

Tom B · 11 Apr 2019 at 20:03

I just bought the new Threadripper Velocity block and took it apart to see if I could flip the ports internally (you can't

)

I cannot for the life of me get it back together. There are two rubber O rings that have to be positioned exactly and I can't do either of them, I've spent an hour pressing the rings into the block and trying to force them into place. How the hell do you get these blocks back together?

Perhaps I shouldn't have taken it apart but at some point I would have had to have cleaned it!

Is there a trick to doing this? I've tried using a spudger to press the ring into the frame, it never stays, I've seen a few videos where the top plate is used to press it into place, I've tried that and cannot get the o-ring into the correct position.

At this point I'm tearing my hair out! I have no idea what else to try.

Got any pictures? I'm struggling to picture what you have

The tiny < 1mm in thickness O-ring needs to be placed in a tiny groove, then the razor looking metal block needs to pin it down. Then the big O-ring needs the same treatment with the larger block.

Very frustrating as I can't get either to sit no matter what I do.

I don’t accept any responsibility if this goes wrong for you

but, I’ve had a similar issue in the past where the o-ring groove wasn’t o-ring shaped. Just ended up using the smallest of small dabs of glue just to get it to sit in the right shape. Worked a treat.

Thanks for the suggestion but I really don't want to try that as if the glue gets stuck in the small gap where the ring should be the ring will never go back in, and it may also slowly get eaten away and swim around the loop.

It should go back in at least partially, you’ll need to push it in and work round the slot. Can be a bit fiddly but it should fit in, usually the annoying thing is it popping out...

You should get it with a little bit of water. Or a tiny smear of silicone grease/oil to hold it in place.

Bear in mind that silicone grease and oil will rot many rubbers over time, water is your friend here.

get some heat into them with some warm water to make them a bit more pliable, put a tiny bit of very low tack masking tape on any part of the o-ring to hold it in position then shape the rest of it into the groove. Put another tiny bit of tape on any parts that insist on popping out and then leave it for a bit so the o-ring rests in shape. Repeat for other o-ring.

Worked lovely for my Aquacomputer DDC top as I was endlessly replacing, fitting and modding the steel plate - them channels were really odd shapes.
