Leaking mcw-6000 64

[Stoneyman]

The only brightside to this post is the block started leaking during a leak test outside the case :p
But i'm really dissapointed considering all the hoops i jumped through to use this block. I had to hunt down a amd speced metal back plate to use on my DFI nf4 ultra-d mobo.
Now the block leaks a little around the bottom of the barbs. I do have the worm type hose clamps installed. and yes they are tight. I must have some pin hole leak arourd where they brazed the barbs on. :shrug:
Looks like it's time to RMA this to swiftech. :rolleyes:

Isn't brazing pretty easy to do? I thought you could use a propane torch.. maybe not though

Brazing would be a option but, i'd rather send this back to swiftech and let em know their block leaked right out of the box new. Maybe they have a design flaw in the manufacturing or something. I have a TDX in standby and she's ready to go. :cool:

have them give you a new one if you can. it's totally not worth it to braze the thing.

make sure that clamps are tight, I got swiftech as well but the clamps that came with the block were useless. It didn't matter how much I tighten the clamps it still leaked, good thing it leaked only a little, bad thing everything was installed

YOu could put a little dye or food coloring in a couple of tubes attached to help you see exactly where it is leaking from. I sure would hate to go through all of the trouble to RMA and it turn out to be something stupid instead.

there blocks have no barbs per say i would try a new quality metal hose clamp and then see

I've seen a few post about people rebrazing the barbs on the block. Either due to a loose barb or what they thought was a bad brazing job.

use alot of plumbing tape on the barbs, i wrapped mine about ten times and the leaks went away

They have no threads, to my knowladge. they are entirly brazed in.

So what did you do and what type of clamps did you use?
i think it's either a pin hole in the braze or a bad design on those barbs?

I doubt that. I have 4 with no problems.

This is also the first 600X block that I have heard of leaking.

Are you use that its the barb on the block, and not the hose-barb connection.

Swiftec presure tests their blocks before shipping, so I can't really see it being the barb-block connnection, but anything is possible.

[bobmanfoo]

its not the barb leaking, its the tube
They have no threads, to my knowladge. they are entirly brazed in.
yes i know they are not threaded, just a straight barb that is eactly 3/8", it was made for the quick connect plugs, since the barb is straight it doesn't make the hose stretch over it at all causing it to leak, if you get plumbing tape and wrap it tight alot of times you will increase the diameter and make the tube stretch stopping the leaking, you could also use that tape to make ridges or peaks by twisting the tape like a string and wrapping it around the barb to make 'rings' then cover it with the plumbing tape

The hose clamp that came with my Swiftech MCW6002-A seem too big.. When I tighten them down they don't touch the hose all the way around.

run to the local department store and but some screw type hose clamps.

I am using those screw type hose clamps. But thanks to everyone for offering advice and ideas on this. You would think these hose clamps would do the trick. I might try the pipe tape idea. Can't hurt to try right?

well the teflon tape (plumbing tape) worked like a charm! Just have to be careful when putting the tubes over it, as it has a tendency to slide down. Thanks for everyones help on this!

if it is sliding down you are not wrapping it tight enough, the should stretch the tape firmly with out tearing it, if you do it right the tape adheres to the barb, try stetching tape out width-wise a little when you are wrapping

[Stoneyman]

Will do! thanks for the tip bobmanfoo.
Hope this helps others out there too. :)
