Help with angle fittings >.<

I've been sorting out my loop layout for my project here: http://forums.overclockers.co.uk/showthread.php?t=18467916

In order to make it work I'll need a right angled fitting, I've got two from a previous build but they leaked so I ordered a bitspower one and it seems like it's going to do exactly the same thing which makes my believe they just aren't compatible with my EK barbs.

The problem seems to be that no matter how tight I try to make them the o ring remains uncompressed...

If I was to add a second o ring would that create a tight enough seal? or is there another way to remedy this?

Thanks

Replace the oring on the barb if it's leaking at the join between the angle fitting and barb.

Even with a replacement o ring it won't seal with one

reiyushin · 16 Jan 2013 at 14:12

It's the same will all 3 fittings, it won't seal but two o rings seems to make a good seal

Anyone done this?

Strange, defective fitting perhaps? Could be an uneven cast causing the problem.

If it was me I would just put some PTFE tape round the thread, problem solved.

Sorry - can you clarify what fitting it is you are using and WHERE it is leaking?

I presume you are using the type which has a compression fitting at one end, and a 1/4 bsp fitting the other.

What are you connecting into? A raditiator? Reservoir? It almost sounds like the thread has been stripped off the vessel you're tapped into...

I'm using this angle fitting: http://www.overclockers.co.uk/showproduct.php?prodid=WC-181-BP&groupid=962&catid=1529&subcat=1852
(I also have tried these: http://www.overclockers.co.uk/showproduct.php?prodid=WC-136-EK&groupid=962&catid=1529&subcat=1852)

with these barbs: http://www.overclockers.co.uk/showproduct.php?prodid=WC-075-EK&groupid=962&catid=1529&subcat=1826

It just seems like there's too much thread on the barb to compress the o ring.

Doubleing up shouldn't cause a prob assuming they compress well, forming a seal, and don't part with side pressure. I do this on my mcw60 gpu block. Always leak test first to make sure ofcourse.

Yea, it's airtight to "as hard as I can blow" standards so it seems fine

It's good good compression now

Hopefully I'll get the loop built this weekend

Use some of these if your worried Linky

I've had a similar issue with some waterblocks - I think my RIIE chipset thread was too shallow too. I ended up switching a barb for one with REALLY short thread on it called a stubby fitting.

See:

Either that or dremel some of the threaded barrel off the fitting you already have...
