GPU waterblock plug keeps leaking.

[DarthSmartt]

On my ek fluidgaming a240g waterblock one of the plugs on the gpu block keeps leaking. I took it out, dried it, dried the o ring, dried where it connects, and leak tested for 12 hours. It was fine during that 12 hours but now it is leaking again. I am tired of dealing with leaks and it is only my second day of doing any kind of watercooling.

Get a new plug or new waterblock. Try testing both to make sure you're replacing the correct part. You can always get a refund if it doesn't need replacing.

sounds like you have a few problems surrounding your build....

 

could you provide the following photos?

 

1. picture of the leak itself

 

2. picture of the threads and o-ring of the stop plug

 

3. picture of the threads inside the you block.

 

Usually a leak is either a loose stop plug or an overtightened one that has stripped the threads.

It sounds like the O-ring or the threads itself are damaged and not able to apply enough pressure to seal it. As said if you can take a photo of the leak and all the components separately that will help greatly.

as a temp fix you can use the plumbers tape(white really thin) thats used to seal screw joints on pipes, chances are its the o-ring that needs replacing or the threads are damaged. Its called PTFE tape here in uk

I think I’ll call up ek to see if I can get a new block and plug since the plug looks fine. I’ll use the Teflon tape method for now.

That is exactly what I’ll do. Thanks! Also in the US it is called Teflon tape.

You sure you didn’t damage it? A lot of people having issues with the kit lately. Being a cheap introduction to water cooling, seeing slot of mistakes along the way. 

 

Ended up cracking one of my cpu blocked. Used some tape to seal it up. Don’t use the tape any more since I swapped fittings and the leak hasn’t came back.

I dont think I broke it. There are no obvious signs of cracking or stripped threads. I did the teflon tape thing and it seems to be sealing it so far. Fingers crossed.

Did you manage to resolve this? I have the same issue. The plugs keep leaking.

Replace the o-ring.  A lot of waterblock mfg's will include orings that are basically one-time-use because they're very thin diameter cross section that gets compressed once and then it's permanently deformed and poor-sealing.

 

The *first* thing I do with every fitting is replace the o-ring with one of my own.
